description: ’Excursion to a story told with pictures’’. This title is indicative of the subject approached in this paper. As part of an educational initiative that on the one hand aims at highlighting the field of cinema literacy and on the other sets the people in the center, the adults who participate in it, will have the ability, through studying the film Excursion, to also follow a path — metaphorically speaking — that ends with a contact with the way of writing a script. The educational initiative presented in this paper, is designed for Thessaloniki’s Cinema Museum
Improved control of water loss from micropropagated grapevines (Vitis vinifera cv. Nebbiolo)

description: Micropropagated plantlets are generally susceptible to rapid desiccation when exposed to reduced relative humidity and require a costly acclimatization procedure. Detached leaves of micropropagated Vitis vinifera, cv. Nebbiolo, plantlets were used to evaluate the relative contribution of leaf cuticle and stomata to water loss. Water loss occurred mainly from the abaxial surface of detached leaves; moreover, a large majority of stomata was still open 3 h after exposure to 63 % RH. An indirect estimation of epicuticular wax suggested a lower wax deposition for micropropagated plantlets compared to acclimatized and field-grown plants of the same clone. A previously developed method to produce hardened micropropagated plants was adopted: 1 mg(.)l(-1) paclobutrazol (PBZ) was added to the medium and culture vessels with reduced relative humidity (rRH) were used during the last stage of micropropagation. Under our experimental conditions, rRH was more effective to reduce transpiration than PBZ; a combination of both treatments improved plant survival during acclimatization.

description: The effects of early and late water deficits on pericarp cell division and enlargement of Syrah berries (Vitis vinifera L.) was determined by DNA extraction and quantification. Different periods and different levels of water deficit were applied between anthesis and maturity to grapevines growing under controlled water supply in two consecutive years. DNA extraction profiles showed that water deficit did not affect cell division. Reduction of berry size and berry weight was caused exclusively by a decrease of pericarp volume, independent of the intensity of the water deficit or the stage of berry development. Decreased cell volume as a result of an early water deficit from flowering to veraison was irreversible. These results support the hypothesis that early water deficits modify the structural properties of the cell components and consequently cell wall extensibility, thereby limiting the subsequent enlargement of pericarp cells.

description: A PCR-specific marker, SCP18, was developed from a RAPD marker linked to a major locus involved in seedlessness, sdI. A preliminary study of the usefulness of SCP18 and SCC8 (a marker linked to sdI previously developed by LAHOGUE et al. 1998) for the marker assisted selection of seedless varieties was realized using various strategies: a posteriori test in seedless x seedless and seeded x seeded progenies and test of their allelic diversity in a set of 81 seedless and seeded varieties. In contrast to SCP18, SSC8 was found to be a useful marker at least in the seedless x seedless progenies and to show a good linkage disequilibrium with seedlessness in our set of varieties.

description: Genetic relationships in a set of important grape genotypes in India, comprising cultivated varieties, rootstocks and wild species were analysed using RAPD markers. A total of 250 bands were obtained by 19 informative primers, most of which could clearly distinguish between the wild and cultivated genotypes. Wild species and rootstocks showed a maximum number of bands (205) and the highest polymorphism (94 %), followed by cultivars belonging to Vitis vinifera (165 bands, 90 %), while cultivars from V. labrusca showed only 75 bands of which almost all were monomorphic. Cluster analysis resulted in the formation of three main clusters. Wild species and rootstocks separated early from cultivated genotypes. Cultivated types formed two separate clusters one consisting mainly of the labrusca and the other of the vinifera types. In the cluster of vinifera genotypes, seeded and seedless varieties were further separated into different subgroups. High bootstrap values at most of the nodes supported the stability of the dendrogram. The grouping of most varieties agreed well with previous reports based on morphological characters as well as parentage, emphasizing the suitability of RAPD analysis for such studies. The present report is the first attempt to determine the genetic relationships in important grape genotypes in India using molecular markers.

description: A set of 73 types of 18 wild grape species native to China, one interspecific hybrid, 7 Vitis vinifera cultivars, the rootstock cultivar SO 4 and one V. riparia accession were investigated using the RAPD technique. The screening of 280 decamer oligonucleotides allowed the selection of 20 primers used for the analysis. RAPD fingerprints of 83 grape samples were obtained. 191 bands, intense and easy to score, were chosen as markers. On average 5.7 bands per primer were amplified with an average of 68.7 % polymorphism. The size of amplified bands ranged from 100 to 3000 bp. Discrimination of 83 samples was obtained with one of two primers (OPQ04, OPJ07) combined with one of 5 primers (OPJ01, OPH19, OPP02, OPA15, OPU16). The average number of bands for each sample per primer was 5.7. This revealed a high level of polymorphism among the wild grapes native to China. RAPD markers proved to be useful for identification as they are quick and easy to use.

description: The present Diploma Thesis deals with the Conceptual Exhibition Planning and Design of a proposed temporary exhibition entitled "The Universe of Greek music discography // songs and people", located in the building of Warehouse 7, at the Port of Thessaloniki. In this proposal, the Exhibition Planning is examined at a simple level, through the exploration of the possibilities of the temporary exhibition, generated by the reference to the characteristics of the Collection, the Project Owner, the Space, the Public and the Cultural environment. Subsequently, the Conceptual Exhibition Design, which reflects a completely structured museum narration, is constructed based on this Planning. The conceptual approach of the exhibition focuses on displaying the milestones in Greek discography, achieving this through the prism of songs and people, as seen from the perspective of record companies and social contexts. Thus, the different record aspects considered as landmarks of each era, form the "Universe of Greek music discography" in its entirety, mingling the visitors of the present with the people of the past

description: Στο βιβλίο τού Cesare Brandi «Θεωρία της Συντήρησης» (1963), όπου προτείνεται ένα ολοκληρωμένο μεθοδολογικό εργαλείο για την πράξη της συντήρησης εν γένει, ορίζεται για πρώτη φορά η έννοια του κενού (lacuna) και η ερμηνεία του, βασισμένη στις αρχές της Gestaltpsychologie : «το κενό είναι μια αδικαιολόγητη, βίαιη διακοπή στον εικαστικό ιστό τού έργου, την οποία αντιλαμβανόμαστε ως οδυνηρή. Το πιο επώδυνο και σοβαρό ζήτημα δε σχετίζεται με το “απών” αλλά με το άτοπα και αυθαίρετα εισαγόμενο, συνεπεία της εγγενούς ανάγκης “αποκατάστασης” της ενότητας, που υπαγορεύεται από την αντιληπτική όραση και τις αρχές της οπτικής μνήμης». Καθώς, στη διαχρονία της, η Ιστορία της Συντήρησης δεν ταυτίζεται με τις υψηλές θεωρητικές απαιτήσεις του πεδίου “συντήρηση της Kεραμικής”, παραγκωνισμένου για ποικίλους λόγους από τους κώδικες δεοντολογίας των επεμβάσεων (ενδεικτικά: απουσία αιτήματος επανάχρησης, υψηλές μηχανικές αντοχές ψημμένου πηλού, όψιμη αναγνώριση του αυθύπαρκτου ρόλου της κεραμικής στην έρευνα, εμφατική παρουσία της Αρχιτεκτονικής στο πεδίο της Αποκατάστασης), η παρούσα μελέτη αποδεικνύεται ιδιαίτερα επίκαιρη. Βασική επιδίωξή της είναι να προβάλει τη συνθετότητα της προβληματικής που διέπει την αποκατάσταση αγγείων και την αναγκαιότητα υιοθέτησης εξειδικευμένου μεθοδολογικού εργαλείου επεμβάσεων, που θα παγιώνει τη στοιχειώδη νομιμότητα (code of ethics), κατακτημένη ήδη για άλλες κατηγορίες μνημείων
description: In “Teoria del Restauro” (1963), Cesare Brandi, initially formulated the definition of lacuna, based on the principles of Gestaltpsychologie; “lacuna is an unjustified, violent interruption in the pictorial fibre of the work of art, conceived as a very unpleasant experience”. However, the most painful and serious problem about lacuna isn’t related to what is adsent but to what is arbitrarily inserted, in consequence of an innate property of human nature; the need for reintegration of a unity, connected to visual perception and the Psychology of the Creative Eye (Rudolf Arnheim). Given the fact that in its duration the History of Conservation-Restoration does not coincide with the theoritical aspect of the “Restoration of Ceramics” (as the specific field -for a variety of reasons- has been neglected by research), this Thesis will contribute to critical questions of “ethics” and their basic principles. Nevertheless, its basic pursuit is to emphasize the need for an adoption of a scientific methodological tool, via which an elemantary legitimacy for the Ceramics’ Restoration will be established in a clear way

description: Στην παρούσα εργασία μελετάται η σημειωτική ανάλυση της κινηματογραφικής ταινίας Η ζωή μπροστά σου (1977), του σκηνοθέτη Moshé Mizrahi μέσω της αφηγηματολογίας και των κινηματογραφικών κωδίκων. Σκοπός της σημειωτικής ανάλυσης είναι να διαφανούν τα βαθύτερα νοήματα της ταινίας μέσω της μελέτης της γενετικής διαδρομής του Algirdas J. Greimas, καθώς και μέσω της ανάλυσης των κινηματογραφικών κωδίκων όπως αυτά παρουσιάζονται σε συγκεκριμένα στιγμιότυπα της ταινίας. Η ταινία στο πρώτο σημασιολογικό της επίπεδο περιγράφει την άδολη αγάπη μεταξύ μιας μεσήλικης εβραίας πρώην ιερόδουλης, επιζήσασα του Άουσβιτς, της Μαντάμ Ρόζας και ενός εγκαταλειμμένου, μουσουλμάνου έφηβου αγοριού από την Αλγερία, του Μωάμεθ (Μόμο). Τα συμπεράσματα της σημειωτικής μελέτης δείχνουν ότι ο θεατής προσλαμβάνει τα βαθύτερα νοήματα από τις καταδηλώσεις και τις συμπαραδηλώσεις του νοήματος μέσω της κινηματογραφικής γλώσσας και των κινηματογραφικών κωδίκων αλλά και μέσω της αφηγηματολογίας, της παραδειγματικής ανάλυσης των ισοτοπιών του Greimas και των σχέσεων που αναπτύσσονται μεταξύ τους. Αναδύονται τα πραγματικά θέματα που πραγματεύεται η ταινία, η ιδεολογία του σκηνοθέτη, καθώς και τα βαθύτερα νοήματα στην θεμελιώδη σημασιολογία της ταινίας
description: In the present work we study the semiotic analysis of the film The Life Before You (1977), directed by Moshé Mizrahi through narrative and cinematic codes. The purpose of the semantic analysis is to reveal the deeper meanings of the film through the study of Algirdas J. Greimas's genetic path, as well as through the analysis of the cinematic codes as they are presented in specific snapshots of the film. The film at its first semantic level describes the unconditional love between a middle-aged Jewish ex-prostitute, Auschwitz survivor Madame Rosa, and an abandoned Muslim teenager from Algeria, Mohammed (Momo). The conclusions of the semiotic study show that the viewer receives the deeper meanings from the manifestations and co-declarations of the meaning through the cinematic language cinematic codes but also through the narrative, the exemplary analysis of the Greimas isotopes and the relations that develop between them. The real issues of the film, the director's ideology, as well as the deeper meanings in the fundamental semantics of the film emerge

description: The achievement of some business goals requires more than individual capabilities and knowledge. Hence, it is necessary for different organisations to work together in order to achieve the goals. In this paper, an innovative agentbased architecture is developed to model ontology mapping and integration in a distributed and dynamic business environment where interactions among organisations may take place at unpredictable times, for unpredictable reasons, and between unpredictable organisations. Functionalities and implementation of involved agents are discussed. In addition, a three-layer user ontologies are introduced. Finally, demonstrations of ontology mapping and integration are presented.
Downward shoot positioning affects water transport in field-grown grapevines

Year: 2015

description: Grape canopies (cv. Nebbiolo) were manipulated to obtain vines with alternatively upward and downward shoots on the same fruit-cane. Downward orientation reduced length and total leaf area of the shoot and water flow through the shoot, but did not modify shoot water potential. Shoot hydraulic conductivity, either evaluated on growing plants or on cut shoot portions, was lower in downward than in upward oriented shoots at all positions along the cane. This supports the hypothesis that downward shoot orientation causes a reduction of the hydraulic conductivity, which in turn reduces the availability of water and nutrients for the leaves growing downstream of the point of conductivity reduction. A mechanism which reduces growth in downward oriented shoots is proposed and practical consequences for viticulture, related to reduced water conductivity in downward-trained shoots, are discussed.

Explicit expressions for the mean, the standard deviation and the generating function of the distribution of the access delay are obtained. By applying numerical inversion on the generating function, we are able to compute values of the distribution. We show that our analytical model is accurate through comparison with simulation.

description: The optimal rate of irrigation of the three wine grapes Sauvignon blanc, Merlot, and Cabernet Sauvignon, grown in a semi-arid environment in Israel, was investigated during 1992 - 1998, The drip irrigation I ate was gradually raised after bud break up to a level of either 0.3, 0.4 or 0.5 Pan A coefficient, and then these coefficients vi ere maintained throughout the rest of the growing season. In an additional experiment the effects of secondary purified recycled effluent and fresh water irrigation was compared in Merlot and Cabernet Sauvignon, irrigated by surface and sub-surface drippers. The nutritional status of the vineyard was followed by leaf petiole and leaf blade analyses carried out at flowering and at harvest. Leaf petiole and blade analyses indicated that the nitrogen status of the vines was adequate. The tissue potassium level in the young vineyard was luxurious (ca, 2-3 % in petiole at harvest), reflecting an abundant supply of It by the soil, while the tissue concentration of P was at a deficient level (ca, 0.1 % and less in blades at harvest). Potassium levels declined as the vines matured, probably as a result of K depletion from the limited soil volume explored by the root system under drip irrigation. Low rates of annual phosphate fertigation (5.6-13.7 kg ha-1 P) raised tissue-P proportionally to the rate of fertigation, Irrigation according to a Pan A coefficient of 0.3, as compared to coefficients of 0.4 and 0.5, significantly reduced tissue-K levels. Irrigation with recycled water (high in NPK) raised tissue-P significantly, The relative depletion of K and P in leaf petioles and blades, from flowering to harvest, was found to be a good indicator of the nutritional status of these two elements. At flowering petiole-P was polynomially and linearly correlated with petiole- and blade-P at harvest, respectively, under a wide range of P nutritional intensities. Leaf blades at flowering and harvest had higher priority for P under low intensity of P nutrition. Suboptimal P nutrition could be diagnosed best by petiole-P concentration at harvest. The inflection petiole concentration associated with optimum P nutrition was 0.413 % P at flowering, which corresponded to 0.133 % P in petiole and blade at harvest time.

description: Ampelographic investigations supported by molecular marker analysis were used to reevaluate the progenitors of the grapevine cv. Muller-Thurgau. From these studies we conclude Muller-Thurgau to be a descent of the offspring of a Riesling and Madeleine Royale (syn. Konigliche Magdalenentraube) hybridisation. The results reveal the importance of true to typeness of the grapevine varieties used for genotyping, parentage analyses, etc.

description: Cell-associated lipopolysaccharides (LPS) were extracted by the phenol-chloroform-petroleum ether extraction method (PCP) from a nopaline strain of Agrobacterium vitis, purified by treatment with DNase/RNase, proteinase K and dialysis, characterized by polyacrylamide gel electrophoresis (SDS-PAGE), and bioassayed on grapevine shoot nodal segments. LPS preparation used for the experiments in planta was a mixture of rough-type LPS, obtained from precipitation with water after PCP-extraction, and some smooth- and rough-type LPS from the remaining phenol phase. Infiltration of an aqueous dispersion of the mixture in concentrations of 25-1000 µ g.ml-1 did not cause grapevine tissue necrosis, and callus formed within one month. When the LPS dispersions were infiltrated in the grapevine nodal segments, 24 h before challenge inoculation with A. vitis (5x102 cells per 5 µ l droplet), they prevented tumorgenesis and tissue necrosis; but, when the pathogen was inoculated at a higher concentration (5x105 cells per 5 CII droplet), these LS applications were active in protecting plant tissue from necrosis and did not prevent tumor induction. The potential role of LPS as candidate molecules in the protection of grapevine from A. vitis infection is discussed.

description: Dans ce travail, nous avons étudié lincidence de quelques paramètres de conservation des vins issus des cépages blancs grecs, Batiki et Rhoditis, sur leur teneur en composés soufrés volatils. Il est demontré que le stade du sulfitage des vins nouveaux joue un rôle important sur la formation de ces substances, ainsi que laération qui entraîne leur diminution. De plus, la conservation des vins en barrique ou en cuve, avec les lies ou non, influence dune manière différente la teneur des vins en substances soufrées volatiles. Influence of white wine conservation conditions on the levels of volatile sulphur compounds In the present study, the effects of various parameters of white wine conservation on the level of volatile sulphur compounds were examined. Wines from the Greek white cvs Batiki and Rhoditis were fermented. H2S was analysed colorimetrically, the more volatile sulphur compounds by headspace-gas chromatography (GC) coupled with flame photometry detection (FPD) and the less volatile sulphur compounds by liquid extraction-GC/MS. The best time to sulphurize a young wine is 5-6 d after the end of alcoholic fermentation in order to avoid the accumulation of sulphur substances, especially in wines intended to age on lees, Aeration of wine causes a notable decrease of the more volatile sulphur compounds, whereas the diminution is less important for the less volatile sulphur compounds. Furthermore, the amount of volatile sulphur compounds is affected by the conservation of wines in barriques or in stainless tanks, the duration of contact of wine with its lees, as well as the duration of conservation.

description: Effects of shoot vigor on the development of transmitting tissue (TT) and pollen tube growth in pistils of Pione grapevines (a hybrid of Vitis vinifera L. and V. labrusca L., tetraploid) were investigated anatomically. Shoot vigor was reduced by root zone restriction and pre-bloom shoot tipping, and was increased by severe winter pruning and application of high concentration fertilizer. The TT development in long and short shoots of the vines without root restriction was also compared. In cross sections of the upper and middle ovaries, a thicker TT and more pollen tubes were found in root zone-restricted vines compared to unrestricted vines. Also, thicker TT and more pollen tubes were observed in less vigorous, short shoots of unrestricted vines. Tipping did not improve the TT development. However, spur pruning and application of high concentration fertilizer to root zone-restricted vines did not inhibit the TT development and pollen tube growth, though shoots grew vigorously. From these results, we conclude that promoted TT development in less vigorous shoots of Pione grapevines allows for more pollen tubes to penetrate into the ovary, resulting in the production of acceptable clusters with a sufficient number of seeded berries.

description: A highly efficient, reproducible method for somatic embryogenesis induction, plant recovery and embryogenic culture preservation has been developed for cvs Chardonnay and Brachetto a grappolo lungo (Vitis vinifera), starting from immature anthers and ovaries. Embryogenic induction efficiency was 2 % and 17 % in anthers for Chardonnay and Brachetto g.l., respectively, and 14 % in ovaries for both cultivars. Embryogenic cultures of both genotypes are still propagating 3.5 years after the initial induction and are still morphogenic. Embryo conversion into plantlets occurred at suitable efficiencies during a 100 d culture for both Chardonnay (37 % and 15 %) and Brachetto g.l. (30 % and 29 %), in the two media tested. Organogenesis was also obtained from cotyledonary leaves of Chardonnay.

description: The effect of Bordeaux mixture on the physiology of leaves of Vitis vinifera L., cv. Touriga Nacional, growing under field conditions in the Douro Wine Region, was evaluated. Especially in late summer, this fungicide modifies the light microclimate and leaf physiological characteristics, namely stomatal aperture and photosynthesis. Leaves treated with Bordeaux mixture showed higher reflectance, whereas transmitted photon flux density and temperature were lower compared to control leaves. Photosynthetic rates of treated leaves increased due to a lowering of both, stomatal and non-stomatal limitation. In addition, transpiration rates were higher, but neither the intrinsic efficiency of water use nor leaf water potentials were affected. Delay of leaf senescence of grapevines sprayed with Bordeaux mixture inhibited scorching of clusters and, consequently, led to higher yields per plant.

description: A three-year-study (1996-1998) was carried out on field-grown Sangiovese grapevines under the temperate, humid climate of the Po Valley (northern Italy) to assess their degree of adaptation to minimal pruning (NIT) as compared to conventional pruning (CP). Evaluation included canopy growth, yield, berry ripening and grape rot incidence. In 1996 leaf function was determined as net assimilation (A); seasonal total canopy light interception and percentage of canopy gaps were also measured. As compared to CP, over the 3-year period MP showed typical features of a more rapid canopy development and earlier growth cessation, higher shoot number with shorter shoots and smaller leaves, higher yields with smaller and looser clusters less susceptible to bunch rot. Must sugar concentration was significantly lowered. Seasonal rates of A recorded on single leaves of the two pruning treatments at different shoot positions were overall similar except for higher A in young MT leaves having a chronological age of about 8-10 d. MP also showed the tendency of retarded leaf senescence. The seasonal total light interception trends indicated a linear increase with formation of leaf area in CP, whereas total fight interception in MT augmented until about 50 % of canopy filling and then remained constant with further leaf area development. This suggests that about half the leaf area produced in the MP vines contributed mostly to mutual shading rather than enhancing light interception capability, and, hence, photosynthetic capacity. The overall data indicate that a satisfactory balance in the minimally pruned Sangiovese grapevines can only be reached with further adjustments of crop level to be performed either as partial winter and/or summer pruning. Nevertheless, in MP vines the consistent feature of looser clusters which are much less susceptible to bunch rot is crucial in an area usually characterized by abundant rainfall at pre-harvest.

description:
Numerous investigations of bilirubin have been reported in the literature. Correlation among these investigations can not be made because of multiple behavioral changes characteristic of the solubilized pigment. This research was initiated to evaluate bilirubin and its associated isomers in identical chemical environments.

Two different solvent systems were experimentally selected to study chemical behavior of bilirubin and occurring photoisomers. A ternary solution consisting of 1:3:1 chloroform:methanol:water was used exclusively in visible spectrophotometric analyses. Also, a pH 10.00 buffer was utilized. This latter system has successfully been used in spectrophotometric and voltammetric work.

Four different photochemical processes have been detected spectrophotometrically, one of which has not been previously reported. In addition, voltammetric potentials of photobilirubin have been determined and compared with bilirubin and biliverdin. This was made possible by a novel extraction procedure permitting investigation of photobilirubin by itself.

description: Η Ελλάδα χαρακτηρίζεται ως χώρα με ιδιαίτερη βιοποικιλότητα. Ωστόσο λόγω της κλιματικής αλλαγής και ανθρωπογενών πιέσεων υποβαθμίζεται η φυτική ποικιλότητα των δασικών οικοσυστημάτων. Από καταγραφές σε περιαστικά δάση, προκύπτει ότι μπορεί να φιλοξενούν σημαντική βιοποικιλότητα, η οποία όμως απειλείται από τον κατακερματισμό των δασών, τη ρύπανση και τις δραστηριότητες των πολιτών. Προϋπόθεση για την εκτίμηση της υποβάθμισης των δασών, λόγω ανθρωπογενών διαταραχών, αποτελεί η εκτίμηση της χλωριδικής ποιότητάς τους. Στην παρούσα εργασία χρησιμοποιούνται οι δείκτες βιοποικιλότητας του Shannon, οι δείκτες «α» και «β» ποικιλότητας του Sørensen και καμπύλες αθροιστικής ποικιλότητας, με σκοπό την σύγκριση και αξιολόγηση έξι τύπων δασικών οικοσυστημάτων των περιαστικών δασών της Θεσσαλονίκης. Παράλληλα έγινε λεπτομερής καταγραφή των παρουσιαζόμενων διαταραχών σε κάθε οικοσύστημα. Τέλος αναλύθηκαν οι οικογένειες των φυτικών ειδών που καταγράφηκαν για την σύγκριση του ποσοστού εμφάνισης διαταραχόφιλων ειδών σε κάθε οικοσύστημα τα οποία υποδεικνύουν την παρουσία διαταραχών και ορίστηκαν τιμές C (δείκτες χλωριδικής ποιότητας) για όλα τα είδη.
description: Greece is characterized as a country with unique biodiversity. Nevertheless, due to climate change and human disturbances the floristic quality of the forest ecosystems gets degraded. From records in peri urban forests, it was found that they can host important biodiversity, which is threatened from forest fragmentation, pollution and human activities. Requisite for estimating the degradation of forests, due to anthropogenic disturbances, is to estimate their floristic quality. In the current paper Shannon’s biodiversity index, α and β diversity Sørensen indexes and accumulative species curves are being used, to compare and evaluate six types of forest ecosystems in the peri urban forests of Thessaloniki. At the same time, a detailed record of every occurring disturbance in every ecosystem was carried out. Finally, plant families from every recorded plant species were analyzed to compare the appearance of ruderal species in every ecosystem which indicate presence of disturbances and C values were defined (floristic quality indices) for all species.
