title: Ripe Ora-pro-nobis (Pereskia aculeata miller) fruits express high contents of bioactive compounds and antioxidant capacity

description: Abstract Pereskia aculeata Miller is a native cactaceae found from the Northeast to the South of Brazil. This plant is recognized by the high nutritional value of their leaves, which are the most used in cooking and folk medicine. However, studies on the chemical characteristics and antioxidant capacity of the ora-pro-nobis fruits are scarce. Therefore, the aim of this study was to determine the best harvest point of the ora-pro-nobis fruits to optimize the content of bioactive compounds and their antioxidant capacity. The fruits were manually harvested, defined by their peel colors in three maturity stages: unripe (green), intermediate (yellowish green), and ripe (yellow) stages. The following attributes were evaluated: soluble solids (SS), titratable acidity (TA), SS/TA ratio, pH, and content of bioactive compounds, such as total chlorophylls, carotenoids, yellow flavonoids, total phenolic compounds, and antioxidant capacity. There was a decrease in the content of chlorophyll followed by an increase in the of total carotenoids and yellow flavonoids, due to the maturity stage. For the total phenolic compounds, it was not observed significant difference between the stages. The antioxidant capacity was quantified by the ORAC method in lyophilized pulp in the unripe (1.95 mmol 100 g-1 trolox) and ripe (3.85 mmol 100 g-1 trolox) stages. The lowest contents were observed in the intermediate (0.80 mmol 100 g-1 trolox in lyophilized pulp) stage. The maturity stage significantly influenced the bioactive compounds of ora-pro-nobis, which presented higher values of total carotenoids, yellow flavonoids, and antioxidant capacity in ripe fruits.

title: Modelling the respiration of mango (mangifera indica l.) using the closed system method at different temperatures

description: Abstract Measuring the respiration rate of fresh products is essential to design correct of packaging systems. For such effect, rates of consumption of O2 and production of CO2, usually are taken are initial data of system comportment. The aim of this work, was modelling the respiration of whole mango (Mangifera indica L.), variety Tommy Atkins using a closed system (CS) at three temperatures (4, 25 and 35°C) and 90 h in storage. Initially, was fitted a mathematic model to predict behavior the concentration of gases as a time function. With this information, two models were fitted to predict the respiration rates. A model based on Michaelis-Menten’s enzymatic kinetics (MM) and a model based on regression model. Also, an equation type Arrhenius was used to evaluate the temperature effect on respiration rate and a semi-empirical model which predict simultaneously the effect of time and temperature. The results showed that the Arrhenius and MM models obtained the best fits. In this system, the respiration rate of whole mango depends of temperature and of gases concentration, in which the respiration rate is inhibited by CO2 and is favored by increased O2.

title: Matrix management interfers in yield and quality of cocoa seedlings

description: Abstract The influence of two managements on yield and quality of plagiotropic mini-cuttings of four cacao clones was evaluated. The design was completely randomized in a 4 x 2 factorial scheme with 4 clones x 2 mother plant management (apical pruning and bending), with 10 replicates and one plant as experimental unit. Seedlings used were propagated by rooting of semi-woody cuttings of plagiotropic branches and at seven months of age, two seedlings of each clone were transplanted to 12 L pots filled with organomineral substrate. After transplantation, the apex of one of the plants was cut based on the count of the first six leaves from the apex. For bending, stems were folded and horizontally fixed. The first collection of mini-cuttings was performed 30 days after transplantation and the others during the following seven months. The yield of mini-cuttings was estimated during collections and part was used for rooting and quality evaluation of seedlings. After 90 days, 10 mini-cuttings of each clone were evaluated for quality using the Dickson quality index (DQI). Another 10 rooted mini-cuttings were transplanted to 1.5 L polyethylene bags and kept in greenhouse for another 120 days until final quality evaluation at 210 days. Data were submitted to analysis of variance and Tukey test at 5% probability. Shapiro-Wilk normality test and Pearson correlation analysis were performed. bending was more efficient in the average production of mini-cuttings especially for BN 34 clone. The Dickson quality index was correlated with root dry mass, at both 90 and 210 days, and the bending technique was responsible for the best DQI. Variable height was not adequate to estimate the quality of cocoa seedlings.

title: Mycorrhizal dependence of citrus rootstock

description: Abstract Plant growth promoting microorganisms, such as mycorrhizal fungi, have been widely used in agriculture because they help plants in the absorption of nutrients and water, influencing their growth. The objective of this work was to verify the effect of the mycorrhizal association of Glomus clarum and Glomus etunicatum on the initial growth of the rootstocks Rangpur lime, Swingle citrumelo and Sunki mandarin. The experimental design was completely randomized with a 3 x 4 factorial arrangement, with five replications, corresponding to three rootstocks, four managements: mineral fertilization, inoculation with G. clarum (IGC), inoculation with G. etunicatum (IGE) and Control. The seedlings were produced in greenhouse, using as substrate the vermicompost earthworm, distributed in polyethylene bags, depositing three seeds of each rootstock / bag. The inoculation with mycorrhizal fungi was carried out at the time of sowing (45 spores of each species / bag). The mineral fertilization was divided into two phases: phosphorus application before sowing (40g of single superphosphate / bag); nitrogen application (1.7 g dissolved in 40 ml of water), divided in eight applications of 5 ml of the solution, via irrigation water, manually and weekly; and micronutrients (B, Cu, Fe, Mn and Zn), sprayed manually every two weeks. The following parameters were evaluated: height, stem diameter, number of leaves, shoot dry mass, colonization and mycorrhizal dependence. There was a significant interaction between the rootstocks and treatments applied in this study for most of the evaluated variables. Rangpur lime and Swingle citrumelo obtained higher height and the management that conferred higher height to the rootstocks was the mineral fertilization and IGE. The largest diameter of the stem was reached by Swingle citrumelo and the management that provided the largest diameter was the inoculation with G. etunicatum. Rangpur lime presented moderate mycorrhizal dependence for G. clarum and marginal for G. etunicatum. Mycorrhizal colonization did not show a significant interaction between rootstocks and the management with inoculation. The mycorrhizal association of G. clarum and G. etunicatum was not presented as the best management for the growth of Rangpur lime, Swingle citrumelo and Sunki mandarin, when compared to the mineral fertilization. However, the inoculation of mycorrhizal fungi provided a positive effect on the uptake of some nutrients by the rootstocks, especially K, Mg, N and P.

title: Morpho-genetic profiling and phylogenetic relationship of guava (Psidium guajava l.) as genetic resources in Pakistan

description: Abstract Guava (Psidium guajava L.) is an open-pollinated crop having 25-40% dissimilarity index which promotes heterozygosity and adds new cultivars. Morpho-genetic characterization of 37 guava accessions was carried out for genetic variability and structure of guava germplasm located in Punjab province, Pakistan. Principal Component analysis (PCA) was subjected to analyze the morphological diversity and for genetic analysis we applied cluster analysis, using the PyElph software. PCA distributed thirty one traits into six components and first two components accounted 39.5% of total variation. A dendrogram constructed on the basis of morphological traits which showed 34% dissimilarity index among thirty seven guava accessions and divided them into 6 groups. For genetic characterization 18 microsatellites were used, the size of reproducible and scorable bands ranged from 150 to 320 bp. The 18 primer pairs amplified 85 alleles with an average number of 4.7 alleles per locus and no more than two displayed bands (nuclear SSR loci). The phylogenetic tree based on molecular analysis showed 50% dissimilarity index among selected guava accessions and separated them into 4 groups.

title: Mango dehydration: influence of osmotic pre-treatmentAnd addition of calcium chloride

description: Abstract Mango (Mangifera indica L.) can be characterized as a greatly accepted fruit due to its sensory attributes of flavor and aroma. However, it has a large production during the harvest season and requires preservation through processing. Osmotic pretreatment, followed by drying, provides products with higher quality and stability. The present study explored the effects of osmotic pretreatment with and without addition of calcium chloride in the nutritional characteristics and sensorial acceptance of dehydrated mango. Four different osmotic treatments were applied in mango slices followed by drying. Drying without osmotic treatment was considered control. Dried samples pre-treated with calcium had lower sugar content and higher retention of acids in the fruit. The increase of sucrose and glucose content during osmotic treatment contributed to maintaining nutritional quality and color of the product when compared with control treatment. Products dehydrated with osmotic pre-treatment were the most preferred, presenting higher purchase intention. The combination of osmotic pretreatment with convective drying provided higher acceptance of dehydrated mango due to its higher quality.

title: Nutrient absorption and accumulation in ‘Paulista’ and ‘Sabará’ jabuticaba cultivars

description: Abstract The amount of nutrients accumulated and distributed in young jabuticaba trees are not yet well known. The aim of this work was to verify biomass production, nutrient accumulation and distribution in ‘Paulista’ and ‘Sabará’ jabuticaba seedlings. The experiment was conducted in greenhouse and seedlings were propagated by seeds and transplanted after 150 days into pots containing perlite and cultivated for 450 days in nutrient solution. Nutrient accumulation and distribution in the different plant organs (root, stem and leaves) were evaluated every 90 days. The mean total nutrient accumulation of ‘Paulista’ and ‘Sabará’ seedlings at 450 days were: N (706 and 611), P (81 and 62), K (541 and 409), Ca (488 and 424), Mg (66 and 54) and S (93 and 92) in mg plant-1 and Cu (1578 and 1635), Fe (20887 and 19652), Mn (13975 and 13434), Zn (4921 and 4048) and B (642 and 764) in µg plant-1, respectively. ‘Paulista’ and ‘Sabará’ jabuticaba seedlings presented the following tendency of nutrient accumulation and distribution among organs: leaf &gt; stem &gt; root. Thus, this work can be a useful reference for studies on the fertilization management in jabuticaba seedlings.
