The objective of this work was to evaluate the phenological patterns, vegetative growth, and yield characteristics of fig (Ficus carica)varieties in Southeastern Brazil. The 'Roxo de Valinhos', White Genova, PI-189, and Troyano varieties were distributed in a randomized complete block design and evaluated in the field. The following characteristics were assessed: number of days between pruning and the beginning of sprouting; leaf chlorophyll content; number of shoots on each branch; length, diameter, and number of internodes on each branch; number of leaves per plant; leaf area; number of fruit per plant; mass, length, and diameter of fruit; production and yield; and duration (days) of each phenological stage, such as thermal requirement models. 'Roxo de Valinhos' and White Genova sprouted the fastest and showed the largest number of shoots. Troyano obtained the greatest branch length and diameter, as well as the greatest number of fruit per plant, which had the shortest diameter and length and the lowest mass of fruit. Furthermore, Troyano showed the latest harvest, besides the thermal requirement of 4,577.31 degree-days. 'Roxo de Valinhos' and White Genova produced fruit with the greatest average mass and diameter and the longest length. Troyano shows better vegetative growth and produces more fruit per plant than 'Roxo de Valinhos', but both genotypes show similar yields.

Abstract:The current study aimed to evaluate the effect of indole butyric acid (IBA) and boric acid to induce rooting on atemoya "Thompson" cuttings. A randomized block design with 10 treatments and four blocks was laid out. The treatments consisted in the use of different levels of IBA (i.e., 0, 500, 1,000, 2,000 and 4,000 mg/L) with or without boric acid at 150 mg/L. The cuttings were placed to root in expanded polystyrene (EPS) trays with 72 cells and kept in a greenhouse under misting. At 120 d after planting, leaf dry and fresh masses (g), root dry and fresh masses (g), percentage of rooting, live cuttings (LC), live cuttings with callus (LCC), number of roots per cuttings and number of emitted leaves (NEL) were evaluated. Data were submitted to analysis of variance and comparison of means by Tukey test at 5% probability. Results indicated no statistically significant differences in both application methods (separate or associated with boric acid) for all evaluated variables, except for LC, in which boric acid provided higher survival rates. It could be concluded that the propagation method using either separate IBA application or associated with boric acid is unsuitable to induce rooting on atemoya "Thompson" cuttings.

The carbohydrate storage is necessary to support the plant growth in periods of stress, during the dormancy, in the beginning of the vegetative development and during the fruiting time. In this context, this work intended to evaluate the carbohydrate concentrations of the peach (Prunus persica (L.) Batsch) tree 'BRS Rubimel', cultivated under subtropical conditions. The experiment was performed at the experimental farm Lageado, of the Faculty of Agricultural Sciences of UNESP at Botucatu/SP. The evaluated peach trees were two years old and were cultivated in the spacing of 6.0 x 4.0 m. The adopted experimental delineation was in randomized blocks, making use of four plants per parcel with four repetitions. The treatments corresponded to the period of the collection of leaves and branches, during the annual cycle, corresponding to January to May and July to December 2012. The sample collection of the roots was performed in January, April, August, November and December 2012. Four fruits per plant were collected. The Gonçalves et al.; BJAST, 9(5): 419-426, 2015; Article no.BJAST.2015.281 420 concentration of starch in the roots of the peach tree were superior to the ones from the branches, from August to December. The carbohydrate with the higher storage level in the peach tree 'BRS Rubimel' was starch. Original Research Article
