“…The pomelo cultivar produced 13 t.ha -1 in Anápolis. Despite the productivity being within the range of growth parameters, this value was lower than the recorded by other authors (Peche, 2016;Ojima et al, 1985). Note that the plants of the Anápolis Experimental Station are in adulthood and in full production (12 years).…”

The Brazilian production of persimmon expanded in recent years, mainly due to the high productivity of the culture. The persimmon fruit is originally from subtropical climate. However, new cultivation areas in tropical regions seem promising, especially altitude regions in the Brazilian savannah. In this context, the objective of this study was to assess production, productivity and fruit quality components of three cultivars of persimmon cultivated in tropical regions. The persimmon cultivars Pomelo, Guiombo and Rama Forte were evaluated in regards to the physical and chemical characteristics of fruits and productivity in two harvest seasons (190 days after pruning and 220 days after pruning). Fruits were obtained from twelve-year-old trees cultivated at the Rural Experimental Station of Anápolis -GO, planted at a spacing of 7 m x 5 m and grafted on common persimmon (Diospyros kaki L.) trees. The cultivars showed reliable levels of productivity, especially Pomelo and Giombo. The cultivar Giombo was the most productive in the region with an average yield of 545 fruits per plant. However, the Giombo fruit had reduced mass (127 g), and were smaller compared to the other evaluated cultivars. Pomelo fruits have higher average fresh mass (224 g), even without standing out with maximum yield. The highest yields were obtained for Giombo and Pomelo cultivars (13.25 and 19.27 ton/ha, respectively). Harvest time influences fruit parameters. The fruit harvested 190 days after pruning exhibited higher SS contents and lower acidity when compared with the other fruit harvested 220 days after pruning, regardless of the cultivar. The fruits on the plant darken over time. The Pomelo cultivar tended to yellowing with the reduction of soluble solids. Rama Forte and Giombo tended to reddening with increasing SS. The fruits of the Giombo cultivar had a higher SS/TA ratio, thus demonstrating that they are tastier compared to the other cultivars. The cultivars Giombo and Pomelo should be prioritized when choosing based on plant production, without worrying about shape and fruit color characteristics.

“…Peche (2016) obtained an average yield with Pomelo persimmon in the Mantiqueira Mountains of 1380 fruits per plant in 2014 and 3 fruits per plant in 2015. There is an alternating production in this cultivar as a natural trait (Ojima et al, 1985;Peche, 2016). In Anápolis a production of 228 fruit per plant was obtained.…”

“…The negative correlation between the number of fruits per plant and the average weight of the fruit ( Figure 2) suggests the possibility of increasing the average weight of the fruits destined to natural consumption through the practice of thinning in the years of high production. This practice has been used successfully in species such as apple (HEHNEN et al, 2012), mandarin (El-ZEFTAWI, 1976) and persimmon fruit (OJIMA et al, 1985).…”

The rejuvenation pruning or plant prune is a practice used in fruits species such mango tree, whose plants can exceed ten meters heigh, compromising the implementation of practices such as spraying and harvesting. This study aimed to evaluate the resumption of production of adult ‘Ubá’ mango trees, previously pruned and subjected to fertilization with increasing levels of nitrogen over five seasons. The experiment was conducted in Visconde do Rio Branco, MG. Nineteen years old mango trees were pruned and reduced to the primary branches, about 1.5 m above the ground. Excess shoots were removed, remaining five to six branches per tree. In the year in which the plants were pruned, the nitrogen fertilization was initiated with different doses, divided into three equal fractions, between October of one year and February of the following year. Annually were applied per plant, 160 g of P2O5 in the form of simple superphosphate, 350 g of K2O in the form of potassium chloride, according to the results of the soil analysis, and 0, 175, 350, 525 and 700 g of N in the form of urea. Two years after pruning the plants returned to production, and in the first five crops, we quantified the production in kg per plant and the number of fruits per plant. The production of the mango trees was already stable in the fifth crop or seven years after pruning. The dose of nitrogen resulting in the maximum yield was 238.9 g/plant.

“…The flower biology of nine persimmon cultivars ("Costata", "Fuyu", "Kaoru", "Mikado", "Okira", "Pomelo", "Rama Forte", "Regina" and "Taubaté") was studied, and among them only "Pomelo" and "Mikado" presented flowers producing pollen (Campos et al, 2015). A breeding program developed by the Brazilian company Instituto Agronômico de Campinas (IAC, Brazil) aiming to undemanding varieties to cold proved the "Pomelo" cultivar to be good male flower producers, ensuring self-pollination (Ojima et al, 1985). The possibility of self-pollination could ensure a higher fruit fixation index rating for "Pomelo" cultivars; however, an average rating of approximately 55% could be noticed.…”

The aim of this study is to evaluate the phenology, yield and fruit physicochemical characteristics of four persimmon cultivars (Diospyros kaki L.) in São Paulo's Midwest countryside, Brazil. The persimmon cultivars studied were 'Pomelo', 'Rama Forte', 'Fuyu' and 'Rubi'. The main phenological phases of persimmons trees were evaluated. Despite significant differences between cultivars in the early and intermediate stages of the plants development such as branch development, full blossom and fruiting's onset, the time required between the fruit's pruning and harvesting was similar among the cultivars. It could be observed that only 'Pomelo' persimmon trees presented male flowers. However on 'Rubi', 'Fuyu' and 'Rama Forte' persimmons trees were found the largest number of female flowers, fruits fixation index and number of fruits per branch. Nevertheless, there were no differences among the cultivars regarding productivity, which could be due to the persimmon fruits physical characteristics. The fruits' diameter growth behavior was evaluated and it was observed that all cases were defined as double sigmoidal, defined by three single phases. Regarding the chemical characteristics, there were no differences among the cultivars' pH and soluble solids content; however, in general, the 'Pomelo' persimmon fruit presented less titratable acidity and a higher maturation index rating.
