Zur Morphologie der Ölkörper der Lebermoose
Authors: Müller‐Stoll Wolfgang R. , Ahrens Gerhard 
Published: August 2010

AbstractDie Ölkörper der Lebermoose sind in Anzahl und Größe bei den einzelnen Arten weitgehend konstant; auch ihre Gestalt ist bei jeder Art typisch. Es werden die Ölkörper der Blätter, der Amphigastrien, der Perichätial‐Blätter usw. bis hin zur Eizelle und den Rhizoiden verfolgt. Aus den Randzellen der Blätter mancher Lebermoose bilden sich Brutkörper, deren Ölkörper in Anzahl und Form stark abweichen. In alten Blättern entstehen Adventiv‐Ölkörper in größerer Anzahl neben den ursprünglichen Ölkörpern. Im Innern der Stämmchen und in den Rhizoiden finden sich keine oder sehr kleine Ölkörper in wechselnder Anzahl.

Das Verhältnis zwischen Artenanzahl und Aufnahmefläche in der Phytozönologie
Authors: Toman Miloslav 
Published: August 2010

AbstractIn der Arbeit wird die Frage der Modelldarstellung des Verhältnisses zwischen der Fläche der phytozönologischen Aufnahme und der Artenanzahl untersucht. Man kann aussagen, daß die Darstellung als Gerade im doppeltlogarithmischen Netz den empirischen wie auch den theoretischen Voraussetzungen sehr gut entspricht. Weiterhin wurde festgestellt, daß beide Werte, bei der graphischen Darstellung eingetragen auf die Koordinaten (Artenanzahl und Flächengröße) sowohl bei den einfach‐ oder doppeltlogarithmischen als auch bei den linearen („Artarealkurven”︁) diagrammen nicht miteinander vergleichbar sind. Daher sind die „Artarealkurven”︁ für die Festlegung der minimalen Aufnahmefläche nicht verwendbar, die kleinste Aufnahmefläche ist von den Anforderungen an die zönologische Analyse abhängig.Um die Verhältnisse im konkreten Bestand zu ermitteln, ist die durchschnittliche Artenanzahl auf zwei Flächeneinheiten ausreichend. Es wird ein allgemeines Gesetz der Abhängigkeit formuliert.

Der Aufbau der Lebermoos‐Ölkörper
Authors: Müller‐Stoll Wolfgang R. , Ahrens Gerhard 
Published: August 2010

AbstractDie Ölkörper der Lebermoose verhalten sich ähnlich wie Vakuolen, d. h. sie ziehen sich bei Plasmolyse in vivo unter Faltenbildung zusammen. In Anwesenheit von quellungsfördernden Ionen wird der Wasserentzug deutlich verstärkt. Das Zentrifugieren der Lebermoose verlagert die Ölkörper in verschiedene Richtungen; vorwiegend werden sie zentrifugal verlagert und zwar zumeist hinter den Plastiden. Es gibt aber auch Fälle, bei denen sie in entgegengesetzter Richtung zu den Plastiden, somit zentripetal bewegt werden. In plasmolysiertem Zustand werden die Ölkörper fast immer zentripetal verlagert. Im polarisierten Licht und im Phasenkontrast ist die Hüllenschicht wenigstens bei großen Ölkörpern deutlich zu sehen. Auch bei der Desorganisation der Ölkörper, wenn sich das Öl in ihrem Inneren zu einer großen Kugel zusammenzieht und schließlich durch Platzen der Umhüllung austritt, ist die Hüllschicht gut zu erkennen. Sobald die ätherischen Öle mit dem Protoplasma in Berührung kommen, wird dieses sofort zerstört. Die Existenz einer besonderen Hüllschicht muß als gesichert gelten.Müller‐Stoll und Ahrens (1990a, b) haben zwei weitere Arbeiten über die Ölkörper der Lebermoose veröffentlicht.

Authors: Gill L. S. , Nyawuame H. G. K. 
Published: August 2010

AbstractEpidermal structure and ontogeny of stomata in 30 species of the family Convolvulaceae from West Africa are described. The epidermal cells are irregularly shaped with arched or sinuous anticlinal and periclinal walls in most of the taxa studied. The cells of Calycobolus parviflorus (Mangenot) Heine and Merremia pterygocaulos (Steud. ex Choisy) Hallier f. are striated. The trichomes are variable: peltate glandular and uniseriate eglandular types have been recorded. Septate and unbranched trichomes have been observed in Convolvulus aschersonii Engl.The leaves are amphistomatic in the majority of the taxa presently investigated. However, hypostomatic leaves are recorded in Evolvulus alsinoides L., Ipomoea leari Paxt., I. nil (L.) Roth, I. pyrophila A. Chev., I. setosa Ker‐Gawl. and Lepistemon owariense (P. Beauv.) Haller f. Anisocytic stomata in C. parviflorus are reported here for the first time.Stomatal abnormalities viz: contiguous stomata in Convolvulus aschersonii and Ipomoea heterotricha Didr., aborted stomata in I. hederacea Jacq. and single guard‐celled stomata in C. parviflorus are reported here for the first time.

Stomatal types in the Umbelliferae and their taxonomic value Tribe Apiaea, subtribe Foeniculinae
Authors: Ostroumova T. A. , Lavrova T. V. 
Published: August 2010

AbstractStomatal types of 65 species representing 32 genera of the subtribe Foeniculinae have been investigated, the material origined from the territory of the USSR and some other regions of Asia and Europe. Anomocytic, hemiparacytic, diacytic, paracytic and anisocytic types have been registered. Predominant types in many genera were anomocytic or anomocytic along with hemiparacytic, rarely a mixture of hemiparacytic and anisocytic; some genera had significant number (sometimes predominance) of diacytic and paracytic types. The genera Kadenia and Macrosciadium were found to be extremely variable as concerns stomatal types.
Structure and development of follicles of Nerium indicum Mill. (Apocynaceae)
Authors: Thomas V. , Dave Y. 
Published: August 2010

AbstractFruit of Nerium is an aggregate of two follicles, developing from a bicarpellary sub‐apocarpous pistil with numerous ovules on marginal placenta. Both the carpels are close to each other by their ventral sides from base to tip as a result of a post‐genital carpel fusion. Ovary wall is homogenous parenchymatous differentiated into outer epidermis, mesodermis and inner epidermis. Epicarp developing from the outer epidermis, is single layered in the early stages of development, but later it becomes multilayered towards maturity. Epicarp is highly folded, possessing stomata and hairs on its surface. Mesocarp is parenchymatous embedding, laticifers and vascular bundles with sclerefied bundle caps. Endocarp is multilayered and sclerenchymatous possessing druse crystals. Separation of the two ventrally fused follicles initiates first and afterwards each follicle dehisces marginicidally. Seeds are oval, cylindrical and covered all over the surface with small brown hairs, but long hairs are also present at one end.
Structure and ontogeny of stomata in vegetative and floral organs of some Apocynaceae
Authors: Inamdar J. A. , Patel R. C. , Mohan J. S. S. 
Published: August 2010

AbstractThe organs investigated are either hypo‐, amphi‐ or astomatic. The epidermal cells are polygonal, isodiametric or elongated with thick straight, arched, sinuous or articulated anticlinal walls. The epidermal cells are septate in the stem of Catharanthus pusillus. Cuticle is papillate or striated. Epidermal cells of the ovary of Thevetia peruviana have minimum length and breadth. Stomata are mostly distributed in between the veins either close to each other or widely separated from each other. The orientation of stomata may either in any direction or parallel to and in the direction of long axes of the organs. The mature stomata are paracytic, anomocytic, anisocytic or with a single subsidiary cell. In the foliar organs great majority of the stomata are paracytic while in the other organs, the percentage of anomocytic stomata is greater. The special features noticed are: arrested development, cytoplasmic connection between near‐ by stomata and contiguous stomata. The ontogeny of anomocytic stomata is haplocheilic or perigeneous, that of paracytic and with a single subsidiary cell syndetochelic or mesogenous while that of anisocytic haplo‐syndetocheilic or mesoperigenous.

Published: August 2010

AbstractChecklists are considered as useful tools for exploration work in plant genetic resources programmes. New information is presented for the checklist of Cuban cultivated plants (ESQUIVEL et al. 1989). 107 species were newly included. For a few other species additional data are given. This information is the result of two further collecting missions in Cuba. Fodder crops predominate, as a result of the cooperation with a specialist in this field. A computerized database was developed allowing not only to maintain the information but also to standardize nomenclatural abbreviations, e.g. authority and protologue.

Cuticular ornamentations in some genera of Euphorbiaceae
Authors: Kulshreshtha K. , Ahmad K. J. 
Published: August 2010

AbstractThe cuticular ornamentations of 33 species belonging to 25 genera of the family Euphorbiaceae have been studied by scanning electron microscopy. In this family seven main types of ornamentations, i.e. striate, reticulate, filigree, ridges, wrinkled, mixed and smooth types have been observed. The prominent type is striate. The present study does not elucidate a clear pattern of relationships between the sculpturings of the family and its taxonomic divisions at sub‐family level; however, the study indicates considerable diagnostic value of cuticular ornamentations at tribal and sub‐tribal level.

Chemotaxonomy of some Ipomoea L. (Convolvulaceae)
Authors: Rao S. R. Shanmukha , Leela M. 
Published: August 2010

AbstractThe leaves of fourteen species of Ipomoea have been analysed for amino acids. A total of 27 amino acids have been identified, including 14 protein 13 non‐protein ones. The dendrogram of cluster analysis indicates that Ipomoea is a heterogeneous taxon and shows eleven species‐clusters. The present data suggests that Merremia tuberosa is an integral constituent of Ipomoea and Quamoclit cannot be treated as a distinct genus. The treatment of Ipomoea batatas under a separate section is justified.

Published: August 2010

AbstractStomatal measurements, x̄L/x̄B, distribution, types and structural variations are discussed for six taxa of Ipomoea L. in Nigeria. Considerable overlaps are recorded in the stomatal quantitative measurements. The taxa investigated are amphistomatous but with higher frequency of stomata on the abaxial surface. The paracytic stomata are frequent and common to all the taxa studied. Nevertheless, the anisocytic, contiguous, amphianisocytic and hemiparacytic types are recorded for the first time in these Nigerian taxa of the genus.

Cuticular studies and their bearing on the taxonomy of some tropical Scrophulariaceae With 58 Figures and one Table
Authors: Nyawuame H. G. K. , Gill L. S. 
Published: August 2010

AbstractThe structure of the epidermis and the ontogeny of the stomatal complex of 26 tropical taxa of the family Scrophulariaceae are described. The epidermal cells depict variations with the cells being straight‐walled on both surfaces, straight‐walled on the upper surface only or sinuously walled on both surfaces. Trichomes are also variable. The different types of trichomes observed include unicellular eglandular, peltate glandular and multicellular eglandular. All the investigated species except Lindernia crustacea and Veronica abyssinica are hypostomatic. During the present study three types of stomata are recorded, viz: anomocytic, anisocytic and diacytic types. Anomocytic stomata follow agenous or hemiperigenous ontogenetic development whereas the ontogeny of anisocytic stomata is either hemiperigenous or hemimesogenous. Within limitations stomatal distribution and frequency could serve as reliable taxonomic characters in the tropical taxa of the family Scrophulariaceae.

Influence of irrigation on dormancy in two species of the Egyptian desert With 3 Figures and 2 Tables
Authors: Elhaak M. A. , El‐Shourbagy M. N. 
Published: August 2010

AbstractThe shrub species Thymelaea hirsuta and the subshrub species Echiochilon fruticosum were irrigated during their dormant period in their natural habitat in the northern desert of Egypt with 0, 70, 140 and 210 mm water levels. Irrigation decreased the transpiration rates of the two species, except with the 210 mm level which increased transpiration rate of E. fruticosum. Although relative water content (RWC) was increased it did not reach the value of the species during the rainy season. Irrigation activated dry matter accumulation, that exceeded the corresponding values during the active vegetative period, at the rainy season. Also, irrigation had broken dormancy of the two species: revegetation was observed and water use efficiency (WUE) was improved. Irrigation with 120 mm level could be more than the needs of E. fruticosum but not for T. hirsuta.
