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.
Effect of Different Regional Climates on Persimmon Quality
Persimmon (Diospyros kaki) is grown in wide climate conditions, which may affect fruit biochemical characteristics such as vitamins, soluble solids and antioxidants. Therefore, the aim of this research is to evaluate the biochemical responses of fruit to these climate variables. For this purpose 5 districts of Kashan, Shahrud, Yazd, Kiasar and Sari were chosen to collect fruits. On November 2012, based on a complete block design ripen fruits were collected and quality factors were measured. The results of this research showed that local climate condition significantly (P < 0.01) influenced fruit biochemical characteristics. Fruit collected from Kashan had the highest vitamin C (1.74 mg /100 ml) acidity (pH = 6.6), while the samples from Shahrud had the highest soluble solids (22.13) and titratable acidity (0.04 mg/100 ml). Fruits collected from Yazd showed significant differences in Chl-and carotenoids contents, 0.07 and 0.42 mg/g, respectively, relative to other sites. These results show that arid and semi-arid districts enhance fruit quality.
Persimmon Production and Commercialization in Brazil: An Overview
IV International Symposium on Persimmon, 2009
Persimmon was introduced into the Brazilian state of São Paulo in 1890 but only expanded its cultivation around 1920 with Japanese immigration. The persimmon growing area in Brazil is now around 8,309 ha, with a production of 164,849 t (FAO, 2006). São Paulo has the largest production areas followed by the state of Rio Grande do Sul. In recent years the persimmon area has increased approximately 10% and the trend is to continue crop expansion. The main cultivars are 'Fuyu', 'Rama Forte', 'Giombo' and 'Taubaté'. The market price for persimmon depends on the cultivar and can vary up to 60% with fruit size and up to 30% in fruit quality. In Brazil, most persimmon production is sold fresh in local markets, and in some growing regions persimmon is commercialized as dried fruit or vinegar. However, recently part of the production has been exported to Germany, Canada, Spain, The Netherlands and Portugal. The future challenges are to improve postharvest and storage techniques together with development of an adequate distribution system to meet the increased market demand. Although persimmon is highly perishable, the fruit can be stored for up to two months in regular air storage and three months in controlled atmosphere, but a rapid loss of fruit quality occurs during shelf life.
Genetic Diversity and Breeding of Persimmon

The genus Diospyros, which is distributed in tropical and subtropical regions of the world, contains hundreds of plant species. However, four species of them have commercial importance. D. kaki Thunb. is the most widely cultivated species of the Diospyros genus. Persimmon (D. kaki Thunb.) is grown in many parts of the world that display subtropical climate conditions. In recent years, the cultivation of persimmon has found renewed interest in various countries of the Mediterranean basin. In China (which is the origin of persimmon) and in Japan and Korea (where it is grown widely), persimmons were selected from some well-known old varieties. Recently in countries such as Italy, Spain, USA, Brazil, Turkey and Israel, persimmons were selected from new cultivars. Currently China, Japan and Korea have the big persimmon germplasm collections with a large number of varieties and other Diospyros species. Also, Italy, Spain, USA, Brazil, Turkey, Israel, Azerbaijan, Uzbekistan and Pakistan ha...

Persimmon cultivation has significantly grown in the Mediterranean Region in recent years. The production concentrates mainly in three astringent cultivars: Kaki Tipo in Italy, Triumph in Israel, and Rojo Brillante in Spain. Therefore, the varietal range expansion is one of the current challenges for persimmon producers in this area. Moreover, the introduction of nonastringent persimmon cultivars is particularly interesting because they can be commercialized immediately after harvest without applying deastringency treatment before commercialization. This study evaluated the harvest period and the postharvest response of six Japanese nonastringent cultivars (Kanshu, Shinshu, Soshu, Suruga, Youhou, Izu). During two seasons, fruit from each cultivar were harvested at two maturity stages. Fruit quality (external color, firmness, and total soluble solids) was evaluated after harvest and after different commercial scenarios (domestic market: 7 days at 20 °C, market to European Union (EU):...
Advancing harvest maturity and improving storability of ‘Triumph' persimmons
2012
Advancing persimmon ripening in South Africa has proved to be a worthwhile strategy to attain early fruit that realise higher returns in the European market. This is currently achieved through use of the growth retardant paclobutrazol (PBZ) applied at a standard rate of 1.5 g per plant. However, even at this standard rate, PBZ results in excessive reduction in vegetative growth and decline in the fruit storage quality. The effect of lower PBZ application rates on fruit maturity and keeping quality, return bloom and vegetative growth was investigated over two seasons in ‘Triumph’ persimmon orchards at Simondium in the Western Cape Province of South Africa. The following treatments were evaluated: untreated control, 1.5 ml PBZ drench on 14 December 2009, 0.75 ml PBZ drench on 14 December 2009 and 17 February 2010, 0.75 ml PBZ drench on 14 December 2009 and 0.375 ml PBZ drench on 14 December 2009. In the second season (2010-2011), trees were left untreated as per current industry pract...
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.
