Peach trees are temperate climate fruit trees most planted in subtropical and tropical regions. This advance of the peach crop is mainly due to the introduction of less cold-demanding new cultivar varieties and which require using less specific techniques, such as plant growth regulators and pruning. Within this context, the objective of this work was to evaluate phenological aspects and the yield potential of the cultivars Granada, Aurora-1, Dourado-2, Douradao, Big-Aurora, Marli and Chiripá, grafted onto the “Okinawa” rootstock, planted in the region of Sao Manuel-SP, during two cultivation cycles. The experimental design used was a completely randomized design with 7 treatments and 5 replicates, with the experimental unit represented by two plants.”Granada” had early harvest in mid-September, and “Chiripá” in late November and early December, in which the former was the early-ripening cultivar and the latter was the late-ripening one. “Aurora-1” and “Dourado-2”, had the highest yield values, 18.95 and 16.57 t·ha-1 respectively, followed by “Big-Aurora” with yield values of 12.13 t·ha-1. For subtropical regions, such as São Manuel-SP, less cold-demanding cultivars are recommended, such as Aurora-1, Dourado-2 and Big-Aurora. The planting of early- and late-ripening varieties, such as Granada and Chiripá, respectively, is an interesting alternative for producers wanting to scale their production.

The evaluation of the new cultivars adaptation and yield potential of Mangifera indica L. provides tools to assist and improve the mango production in different climates conditions. This study aimed to evaluate the phenological and reproductive development of five mango cultivars (Bourbon, Haden, Palmer, Parwin and Tommy Atkins), on climate conditions in dry land and four production cycles (from 08/2007 to 01/2011), at S?o Manuel, S?o Paulo state, Brazil. The variables were total plant height, trunk height, stem diameter and the first insertion diameter, fruits physical characteristics, yield and harvest period, flowering seasonality and morphological characterization of the inflorescences. It was found that the four-year-old plants of Haden cv. reach 4.0 m high and 0.20 m of trunk diameter. Bourbon cultivar had the highest flowering period, from April to October. Tommy Atkins cv. had productivities of 14779.07 kg·ha-1 in the fourth cycle and the productivity of Bourbon, Haden and Palmer cultivars was alternated.

The carbohydrates translocation and consequently growth and production of fig tree (Ficuscarica L.) vary according to the different management on cultivation conditions. The aim of this study was to evaluate the changes in the levels and total carbohydrates accumulation together with growth and “Roxo de Valinhos” fig trees production onimplementation of orchards in initial phase, cultivated with and without irrigation. We adopted a factorial arrangement (2 x 7) with four repetitions distributed in installments (with and without irrigation) subdivided in time (collect time). Destructive analyzes were performed at 40, 80, 120, 160, 200, 240 and 280 days after pruning (DAP) and are measured: stem diameter and branch, stem length and branch, number of leaves, internodes and fruit. Subsequently, the plant parts were sectioned to obtain the leaf area, length and roots volume, fresh and dry matter weight. The number, weight and total productivity of fruits were evaluated. The media of all growth attributes and production characteristics were higher in treatments with water irrigation. The total carbohydrate content was higher at 120 and 160 DAP and the carbohydrates accumulation was increasing for most institutions over the plants development, except for the leaves that showed a decrease in the levels at 160 DAP. The fruits showed greater carbohydrates accumulation in relation to the other evaluated organs.

The abscisic acid (ABA) is related to the formation of certain polyphenols, such as anthocyanin, improving the nutritional and commercial quality of the red grapes. In this study, we verified whether the exogenous application of?S-ABA favors the accumulation of anthocyanin, the total phenolic compounds and the antioxidant activity of the?‘Rubi’?grape. The experiment was performed during the cycle 2014/2015 with the?‘Rubi’?vine (Vitis vinifera?L.) grafted in the rootstock 420-A. The experimental design was composed of randomized blocks, with four treatments and six blocks, in a total of 24 experimental parcels, constituted of one plant each. We used the?S-ABA isomer in different concentrations and times of application, 400 mg·L-1?S-ABA in the beginning of the ripening (BR);400 mg·L-1?at BR + 200 mg·L-1?at 25 days after first application (DAFA);400 mg·L-1at BR + 400 mg·L-1?at 25 DAFA;besides the control (0 mg·L-1). After 40 days of the first application, the samples were harvested and we verified that the?S-ABA induced the accumulation of anthocyanins and total phenolic compounds in the?‘Rubi’?grape. From these results we can recommend two applications of?S-ABA, 400 mg·L-1?at BR + 200 mg·L-1?at 25 DAFA.
