title: Cocoa propagation, technologies for production of seedlings

description: Abstract The vegetative propagation in cacao has been used in Central America since the beginning of the last century. However, only from the end of the century this technique has been intensified in the state of Bahia, where vegetative propagation changes have increased the yield of cocoa growing areas, especially those using other technologies associated with clonal seedlings. The use of clonal garden to collect stems in nursery can reduce by 80% the space required for maintenance of stock plants. On the other hand, the buds obtained from orthotropic and plagiotropic shoots are used to improve the performance protocols and reduce production costs of seedlings. Among the current and future challenges in the production of cocoa seedlings emphasizes the somatic embryogenesis and rootstock with disease resistance. These technologies to increase the productivity of the crop and permit Brazil return to the exporter condition of cocoa beans, which does not occur for more than two decades.

title: Bioactive compounds and antioxidant activity three fruit species from the Brazilian Cerrado

description: Abstract The aim of this study was to determine the content of bioactive compounds and antioxidant activity present in three fruit species from the Brazilian Cerrado: carnauba (Copernicia prunifera (Mill.) H.E. Moore), murici (Byrsonima crassifolia L. Rich)and oiti (Licania tomentosa (Benth) Fritsch). Among analyzed fruits, oiti showed the highest total phenolic content (1236.42 ± 34.06 mg GAE 100 g-1) followed by murici (468.90 ± 27.30 mg GAE 100 g-1) and carnauba (314.44 ± 9.50 mg GAE 100 g-1). Regarding the antioxidant activity, murici showed 4350.31 ± 1.85 µmol TEAC.100 g-1 and oiti showed 14721.69 ± 0.85 µmol TEAC.100 g-1. In addition, high content of anthocyanins was verified in carnauba (9.35 ± 0.00 mg-cy-3-glu.100 g-1), as well as carotenoids (20.0 ± 1.23 mg-ß-carot.100 g-1) and vitamin C (58.60 ± 1.32 mg.100 g-1) in murici. In conclusion, data obtained add valuable information to the current knowledge on the nutritional and functional features of fruits from the Brazilian Cerrado that have been scarcely explored, such as those analyzed, which showed high content of bioactive compounds and antioxidant activity.

title: Physicochemical and microbiological dynamics of the fermentation of the ccn51 cocoa material in three maturity stages

description: Abstract The physicochemical and microbiological dynamics during the fermentation phase of the CCN51 cocoa material was evaluated in three maturity stages (stage 2: 130-152 days after anthesis (DAA), stage 3: 153-174 DAA, and stage 4: 175-196 DAA). Through the microfermentation technique, the physicochemical variables (pH, titratable acidity, total soluble solids, and fermentation index) were monitored every 24 hours. The microbiological dynamics were evaluated by counting the colony forming units (CFU) in a plaque, quantifying three types of microorganisms (Bacillus, acetic acid bacteria and yeasts). In the three maturity stages assessed, a decrease in the pH of the beans was observed as the fermentation progressed; between 72 and 96 hours after fermentation, the pH of stage 4 beans was different from stages 2 and 3. Simultaneously, an increase in the pH of the pulp was observed without differences between the stages. Brix degrees did not show statistical differences between stages, however, the values of total soluble solids showed that the microorganisms present in stage 3 were more effective in metabolizing these in comparison with those of stages 2 and 4. Regarding the fermentation index, stage 4 reached the maximum value (1.35 ± 0.16) at 120 hours, meanwhile stages 2 and 3 reached it at the end of the fermentation (1.35 ± 0.01 and 1.55 ± 0.29, respectively) at 168 hours. The microbiological dynamics in the three cocoa fruit maturity stages evidenced the absence of lactic acid bacteria and the presence of mesophilic aerobic bacilli. Yeasts were present throughout the fermentation in the three maturity stages, being more favored by stage 2, meanwhile, acetic acid bacteria were favored by stage 3. Outstanding microorganism species were characterized molecularly as Pichia kudriavzevii,Bacillus subtilisBacillus megaterium, and Bacillus tequilensis. Stage 3 showed the best characteristics to obtain good quality cocoa.

title: Physiological potential of seeds and morphological characterization of Campomanesia adamantium seedlings

description: Abstract The cultivation of native fruit species depends on the existence of consistent technical and scientific information on the germination and vigor of seeds for efficient management by seedling producers. The evaluation of the physiological potential of seeds is performed through germination and vigor tests, which must be standardized to ensure the generation of accurate information. For Campomanesia adamantium, information on parameters for conducting physiological tests is scarce. The aims of this work were (i) to evaluate the effect of temperature and seed positioning on the substrate for seed germination and vigor, and (ii) to characterize and describe the essential structures and main types of seedling abnormality. After harvest, fruits were pulped and, after seed extraction, germination tests were carried out for 42 days at three temperatures (20, 25 and 30 °C), with seeds positioned in the germination substrate in two ways (between paper and on paper). Seed vigor was evaluated by means of the first germination count (performed on the 20th day) and the germination rate index. The temperature and substrate interaction did not influence variables under study. The position of seeds on the substrate did not influence the physiological potential results. No differences were observed between seed germination temperatures; however, seeds submitted to germination at 25 °C showed higher vigor compared to the other temperatures. Germination and vigor tests, based on seedling performance, should be performed at constant temperature of 25 °C and seed positioning between paper and on paper may be used. Germination in C. adamantium was characterized as epigeal.

title: Impact and management of diseases in the propagation of fruit plants

description: Abstract Well-formed and healthy propagative material is essential for economic success in fruit growing. The health of the seedlings must be ensured during production to prevent the death of plants and spread of pathogens to new areas, which cause an increase in production costs and reduction in yield, with some pathogens making production unviable in the areas where they are introduced. The most viable strategy for disease control in propagative material is the use of resistant cultivars. However, for many fruit cultivars sources of resistance have not yet been identified and in some cases the resistance is “broken” by the emergence of new races of the pathogen. Other measures are also important and recommended in plant propagation, such as the use of integrated disease management, the use of cultural and biological methods, substrate preparation, irrigation management, grafting, balanced nutrition and use of organic matter, eliminating the initial inoculum, and reducing the disease rate. Among the various procedures in nurseries for ensuring the health of seedlings are the use of pathogen-free seeds and cuttings, handling of substrates in clean facilities, disinfection of hands, tools and containers, maintenance of water quality for irrigation, and the elimination of invasive plants. It is important to clean the nurseries and have a suitable place for the disposal of seedlings, substrates and crop residues. A record and history of the operations in the production of seedlings should be a routine, as well as security and control in access to greenhouses or nurseries. The application of knowledge and the best strategies of integrated disease management for the production of healthy seedlings, guarantees the quality of the productive material and the success of the crop.

title: Foliar gas exchange, fruit quality and water use efficiency of cape Gooseberry under different irrigation depths and mulching at greenhouse conditions

description: Abstract The current study aimed at evaluating gas exchanges, yield, water use efficiency and fruit quality of cape gooseberry in response to different irrigation depths with or without mulching of oat residues on pots at greenhouse conditions. Four irrigation depths were tested: 50%, 100%, 125% e 150% of reference evapotranspiration (ETo). Leaf gas exchanges were evaluated by an infrared gas analyzer at different stages of the crop. Throughout the harvest, yield per plant and yield components were assessed in conjunction with water-use efficiency (WUE) and fruit quality responses. Stomata conductance at the flowering and fructification stages showed a smaller limitation under the treatments 125 and 150%ETo. It should be noticed that the aforementioned treatments increased in 83% fresh fruit mass per plant in comparison to 50%ETo. We found a higher instantaneous water-use efficiency throughout flowering under 150%ETo, as well as at the fructification under 125%ETo treatments. Nevertheless, under 125%ETo conditions without mulching the greatest WUE was found, whereas the lowest WUE was obtained under the 50%ETo treatment with no mulching. The treatment 125%ETo resulted in the highest SS and pH, whilst the treatment 150%ETo with mulching evidenced the highest Ratio along with the lowest total acidity observed.

title: Physical and chemical variability of Camu-camu fruits in cultivated and uncultivated areas of the Colombian Amazon

description: Abstract Camu-camu (Myrciaria dubia, Myrtaceae) has the highest reported vitamin C concentrations of any native Amazonian fruit tree species, with increasing demand in domestic and international markets. With the goal of aiding management and conservation programs, we studied the diversity of camu-camu in cultivated and uncultivated areas, based on physicochemical characterization of the fruits. We evaluated 2,250 fruits from 87 plants from six localities of the Tarapacá district (Amazonas, Colombia) and from the Amazonian fruit germplasm bank of Agrosavia (Meta, Colombia). We found high physicochemical variability within and among localities, and superior fruits in the localities where non-cultivated plants were sampled, especially Pechiboy. Using correlations and principal component analyses, we identified the variables Brix value, ascorbic acid content, fruit weight and pulp yield as the most useful for intraspecific selection of plants. The most promising plants presented Brix values of 8.2 ± 0.88 (maximum 10.9), fruit mass of 14.4 ± 1.2 g (max. 18.4 g) and pulp yields of 0.82 ± 0.02 (max. 0.87). These plants can be considered as possible sources for future breeding work. We conclude that there are plants in Tarapacá with relevant characteristics for commercialization and improvement of the species.
