title: STARCH AND SODIUM HIPOCHLORITE ON IN VITRO ROOTING OF PINEAPPLE ‘GOLD’ AND ITS EFFECTS ON ACCLIMATIZATION

description: This study aimed to evaluate the total or partial replacement of agar by corn starch and cassava starch and physical sterilization in autoclave for chemical sterilization with sodium hypochlorite (NaClO) in development of pineapple ‘Gold’ plantlets. The gelling agents used were: M1: agar (6.0 g L-1); M2: corn starch (60.0 g L-1); M3: agar (3.0 g L-1) + corn starch (30.0 g L-1) and M4: agar (3.0 g L-1) + cassava starch (30.0 g L-1). The sterilizations were made by autoclaving at 121°C or by using the solutions of NaClO at the concentrations of 0,003% to rinse the glassware and 0,0003% for addition to the culture medium. After one month of in vitro cultivation, it was observed no negative influence of NaClO and gelling agents in the rooting in vitro of shoots for most parameters evaluated. The plantlets derived from in vitro phase were taken to acclimatization in greenhouse for 90 days. During the acclimatization, the plantlets derived from treatments with chemical sterilization did not differ from the ones derived of autoclaved media to any parameter evaluated, whereas the combination agar + corn starch provided inferior results among gelling agents.

title: MORPHOANATOMY LEAF OF CUPUASSU PLANT ESTABLISHED FOR DIFERENT METHODS OF SPREAD AND SHADOWING

description: ABSTRACT The objective of this study was to evaluate the effect of shadowing and propagation methods in morphoanatomy and establishing cupuassu. The field experiment was conducted in a randomized complete block design with four replications of 10 plants each. For growth analysis was used to plot sub - divided (five times - plot, three levels of shading - subplot and four methods of propagation - sub - subplots). For evaluation of biometrics plant was used scheme subdivides plot with shading in the plot and subplots propagation methods; and the analysis morphoanatomic considered the randomization in blocks of shading. Analyses of growth were performed every 90 days and morphoanatomical at 15 months after planting. The thickness of the spongy parenchyma was higher in shaded leaves by 50 % screen; other features morphoanatomic suffered no significant influence of shading levels. Seedlings with initial development in nurseries reached higher relative growth rate and absolute. The highest relative growth rates and absolute were obtained in culture under 50 % screen, followed by the consortium (45 %). The worst performers in all traits were observed in plants grown in full sun.

title: GROWTH AND NUTRITION OF CACAO SEEDLINGS INFLUENCED BY ZINC APLICATION IN SOIL

description: ABSTRACT Levels of Zn in tropical soils profoundly influences growth and nutrition of tree crops. Research was undertaken to assess the effect of soil Zn on growth and nutrition of clonal cacao tree seedlings of PH 16. Three acidic Oxisol soils differing in texture were used with nine doses of Zn (0, 1, 2, 4, 8, 16, 32, 48, and 64 mg dm-3). Rooted clonal seedlings were grown in plastic pot with 11 dm-3 of the soils at varying Zn levels for 240 days. At harvest growth (dry matter mass of leaves, stems, shoots, roots, and total) and nutrient concentrations were determined. The clonal cacao seedlings showed differences for production of dry matter mass and foliar nutrient concentrations for P, K, Ca, Mg, Mn, Fe, Zn, and Cu. There was Zn toxicity in all soils.

title: MOLECULAR CHARACTERIZATION OF Colletotrichum spp. ISOLATES ASSOCIATED WITH POST-BLOOM FRUIT DROP

description: ABSTRACT Postbloom fruit drop of citrus (PFD) is a serious disease of this crop, accounting for high yield losses. Usually, this disease shows to be limiting when there are prolonged rainy periods during plant flowering or when there is intense leaf wetness. Two Colletotrichum species are associated with the disease: C. acutatum and C. gloeosporioides. However, recently, it has been found that, even under not so favorable conditions, the disease has occurred with some frequency; one suspects the involvement of other Colletotrichum species or new adaptation conditions of the described species. This study aimed to determine whether there is another Colletotrichum species associated with PFD and the viability of using molecular markers ISSR for taxonomic characterization of Colletotrichum spp. isolates associated with PFD symptoms in flowers, as well as of leaf tissues and asymptomatic citrus fruits. For this purpose, we used a combination of specific primers, taking into account the ITS region and ISSR molecular markers. ISSR markers have proven to be effective for taxonomic characterization of the Colletotrichum isolates analyzed. The population assessed consisted only of C. acutatum and C. gloeosporioides, discarding the involvement of an additional species. We found high genetic diversity among the isolates analyzed, which is also shown as converging to the phenotypic differences observed under field conditions. However, no relation was found regarding the origin and associated Colletotrichum spp. species. In an unprecedented way, although asymptomatically, we detected the presence of a C. acutatum isolate associated with citrus fruits.

title: SUNBURN PROTECTANT DECREASES THE INCIDENCE OF BULL'S EYE AND WHITE ROTS IN ‘FUJI STANDARD’ AND ‘PINK LADY’ APPLES

description: ABSTRACT Bull's eye rot (Cryptosporiosis perennans) and white rot () are aBotryosphaeria dothideamong the major apple summer diseases in Brazil. The aim of this study was to evaluate the effect of a protective film consisting of carnauba wax and clay (Raynox®) at doses of 2.5% and 5.0% in infection of C. perennans and B. dothidea in ‘Fuji Standard’ and ‘Pink Lady’ apple cultivars. Apple trees were sprayed five times from December 2007 to March 2008, as predicting of adequate conditions for the occurrence of fruit damage and growth. At harvest, the apples were inoculated with both pathogens and evaluated for incidence of decay. Indifferent to dose, the use of Raynox® reduced the incidence of white rot and bull's eye rot in 67% and 42% in ‘Fuji Standard’, and 43% and 42% in ‘Pink Lady’, respectively. Increasing the dose increased the efficiency of the product for the control of bull's eye rot. At dose of 2.5%, control of bull's eye rot was 19% and 20%, respectively, of ‘Fuji Standard’ and ‘Pink Lady’ apples, while for the same cultivars, but with dose of 5.0%, these values were 65% and 63%. More studies are needed to adjust the dose and application criteria for the sunburn protectant could be recommended.

title: PHENOTYPIC VARIABILITY IN FEIJOA FRUITS [Acca sellowiana (O. Berg.) Burret] ON INDIGENOUS LANDS,QUILOMBOLAS COMMUNITIES AND PROTECTED AREAS IN THE SOUTH OF BRAZIL

description: ABSTRACT Phenotypic studies with native fruits are important sources of information for understanding the status of conservation of plant species, especially populations in protected areas (PAs). Fruits of 18 populations of feijoa [Acca sellowiana (O. Berg.) Burret] present in three kind of PAs, Quilombolas Communities (QLs), Indigenous Lands (ILs) and Conservation Units (CUs) were evaluated with the aim to characterize the phenotypic variability. Fruits were harvested at maturity and eight morphological descriptors were measured: diameter, length, total weight, pericarp weight, pulp weight, pericarp thickness, pulp yield and solid soluble contents (°Brix). The results revealed the existence of large morphological variability for all traits, with significant differences among all populations and among those populations grouped in QLs, TIs and UCs, particularly to the total weight and peel thickness. There was a clear formation of five major clusters of genetic dissimilarity. In addition, two Uruguayan type populations and 16 Brazilian type populations showed contrast means for most of the evaluated traits. The lower variability on fruit characters found in plants collected in areas of traditional people but not in CUs suggests the existence of selection processes of feijoa genotypes on those areas.

title: ANTIOXIDANT CAPACITY OF PEQUI (Caryocar brasiliense Camb.) PULP IS PRESERVED BY FREEZE-DRYING AND LIGHT-RESISTANT PACKAGING

description: ABSTRACT Pequi (Caryocar brasiliense Camb.) pulp is rich in bioactive compounds. However, seasonality and perishability limit its availability in the market. This work aimed to determine the physicochemical characteristics, including phenolic compounds and carotenoid concentrations, as well as the antioxidant capacity of lyophilized pequi pulp during storage in various packaging materials for 180 days. Pequi fruits were pulped, ground, freeze-dried and then vacuum packaged in transparent polyethylene (TP), polyethylene coated by aluminum foil (PA) and laminated foil (LA), respectively. The samples were stored under controlled temperature, humidity and luminosity. Proximate composition, phenolic compounds and carotenoids concentrations, and antioxidant capacity (DPPH• assay) were determined at the beginning of the study and the end of each month, during 180 days. Lyophilized pequi pulp had 48.87, 6.17, and 4.20 g.100 g-1 lipids, proteins, and total dietary fiber, respectively, and 556.79 kcal.100 g-1 energy. PA and LA had similar effects against light-induced carotenoid oxidation. Negative correlations between the phenolic compound concentration and storage period, and antioxidant capacity and storage period; and a positive correlation between antioxidant capacity and phenolic compound content were observed. Light-resistant packaging decreased the carotenoid loss. Among the packaging, LA preserved the phenolic compounds and antioxidant capacity most effectively.
