Abstract: The history of the Japanese persimmon (Diospyros kaki Thunb.) industry in China is reviewed based on ancient literatures. Persimmon (Diospyros L.) and its distribution in China are surveyed according to specimens and their collecting sites, which were preserved in Herbarium affiliated with the Chinese Academy of Sciences. The cultivar evolution of Japanese persimmon and the characteristics of main commercial cultivars in China are described in brief. In addition, traditional utilizations of genetic resources of persimmon in China, including fresh fruits, dried persimmon, timber, pharmacy and ornamental plants are summarized. Cultural activity related to persimmon is introduced in this paper. 1. Introduction Japanese persimmon (Diospyros kaki Thunb.) is one of the ancient fruit trees in China (Table 1). The Chinese name of persimmon (Diospyros L.) first appeared in Li Ji·Nei Ze (around 450 BC , written by Kong Ji, grandson of Confucius), where it was considered a precious food during the Warring States Period (475-221 BC). In another famous work, Shang Lin Fu (written by Sima Xiangru about 120-118 BC), the author, observed that Japanese persimmon was one of the fruit crops planted in Shanglin Garden, a royal garden of the West Han Dynasty (206 BC - 23 At that time it was regarded as a fantastic plant enjoyed by the few (Xin, 1983). Until the South and North Dynasty time (386-589 AD ), Japanese persimmon was popularized due to the technical developments of graft and removing astringency. It was cultivated on a large scale since Tang and Song Dynasty (618-1279 AD), when some cultivars also appeared (Fig. 1). It was then utilized widely, as a woody grain plant in the Yuan, Ming and Qing Dynasties and the early stages of the Peoples Republic of China (1271-1963 AD).

Nowadays, as a seasonal fruit crop, Japanese persimmon has developed from the odd scattered planting to scaled and standardized production, with the technical innovation of cultivation and processing (Fig. 1). According to FAO statistics (2006), Japanese persimmon acreage and production were 653,200 ha and 1,987,000 tons respectively on the China mainland. This represents 3% of Chinese fruit harvesting area and yield (rankings 9th) and accounts for 89.6 and 66.8% global acreage and production of Japanese persimmon, respectively (ranking 1st in the world). 2. Persimmon (Diospyros L.) and its distribution in China According to Flora of China (the 60th volume first fascicule, 1987) records, there are 57 species, six varieties and one form of persimmon distributed from tropical to subtropical regions of the southwest and southern China, but few in temperate zones. The English edition of Flora of China (the 15th volume, 1996) lists the number of persimmon species as up to 60. At present, specimens of a total of 64 species are preserved in Herbariums affiliated with the Chinese Academy of Science. Information on their collecting locations is collected and listed in Table 2. 3. Cultivar formation of Japanese persimmon and the characteristics of main commercial cultivars Persimmon was classified in the jujube group before the Han and Jin Dynasty; date plum (D. lotus L.) is still being termed as soft jujube (Sun, 1983; Xin, 1983). Japanese persimmon was planted scarcely in the Han and Jin Dynasty (206 BC - 420 AD), thus there was no concept of cultivar at that time. In the North and 240 South Dynasty (386-589 AD), accompanied by the application of graft technique, excellent individuals were conserved and further spread through asexual propagation. Consequently, to distinguish different populations, cultivars were named initially based on some prominent characters: i.e. Dashi (Big fruit persimmon), Xiaoshi (small fruit persimmon), Hongshi (red fruit persimmon) and Huangshi (yellow fruit persimmon). Colonies were widely cultivated after the Tang and Song Dynasty (618-1279 AD), and at that phase landraces began to be denominated according to their most notable characters in the different regions, and this was also when veritable cultivars emerged. In terms of an incomplete statistic, 74 Japanese persimmon cultivars were recorded in ancient Chinese literatures (Wang et al., unpublished). A total of 1,072 Japanese persimmon names, including synonyms, homonyms and some extinct cultivars have been found according to investigation by Wang (unpublished). Currently, 560 persimmon accessions are preserved in the National Fruits Germplasm Repository for Persimmon. Most Japanese persimmon cultivars in China belong to pollination constant astringent (PCA) types. Wang (1983) first reported PCNA (pollination constant non-astringent) type ‘Luotian-tianshi’ existing in the Dabieshan region surrounding Luotian county and Macheng city of Hubei province. In recent years, apart from ‘Luotian-tianshi’ persimmon, a series of new PCNA types were believed present in the same area where ‘Luotian-tianshi’ was found (Yonemori et al., 2005) and a new pollination constant non-astringent (PCNA) cultivars was released by Yi et al. (2004) (Fig. 2). Usually, traditional cultivars are utilized for drying persimmon or fresh fruits, some of the principal cultivars include: ‘Fuping-jianshi’ (Fuping county, Shaanxi province), ‘Binxian-dingjianshi’ (Binxian county, Shaanxi province), ‘Ganmaokui’ (Dabashan region located at the cross zone of Hubei, Shaanxi, Sichuan, Gansu provinces), ‘Gongcheng-shuishi’ (Gongcheng county, Northeast Guangxi Chuang Autonomous Region) and ‘Jumishi’(Southeast Shanxi province) can cover more than 6,667 ha; ‘Boai-bayuehuang’ (Boai county, Henan province), ‘Xingyang-shuishi’ (Xingyang county, Henan province), ‘Heze-jingmianshi’ (Heze city, Shandong province), ‘Xiaoezi’ (Weifang city, Shandong province), and ‘Anxi-youshi’ (Anxi county, Fujian province) cover an area of about 3,333 ha; also ‘Mopanshi’ (PCA), centralized in Fangshan district of Beijing city and Mancheng county of Hebei province. In the last decade, some cultivars with better economic value have extended quickly, such as ‘Jirou’, ‘Fuyuu’ and ‘Youhou’ (PCNA), and ‘Mopanshi’, ‘Gongcheng-shuishi’, ‘Fuping-jianshi’, ‘Yongdinghongshi’, ‘Hai’an-xiaofangshi’ and ‘Tailihong’ (PCA). Characteristics of the main commercial cultivars are shown in Table 3.

Fig. 2 - ‘Eshi 1’, a Chinese PCNA cultivar, newly found in Luotian county, Hubei province. 4. Utilization of persimmon and product development Historically, persimmon (eg. D. kaki, D. lotus, D. oleifera, D. glaucifolia, D. rhombifolia, D. discolor, D. ebenum, D. morrisiana) was employed as a fruit tree. At present, D. kaki and seedless date plum (D. lotus) are still important for their edible fruits, while D. kaki, D. lotus, D. oleifera and D. glaucifolia are used as rootstocks. D. hainanensis, D. morrisiana, D. glaucifolia, D. ebenumeriantha, D. ferrea, D. maritima, D. potingen sis, D. rubra, D. longibracteata and D. dumetorum are sources of timber. D. kaki, D. morrisiana, D. lotus, D. glaucifolia and D. maritima (used for fruits, medicine, fish anaesthetic) have medical value. D. oleifera, D. eriantha, D. potingensis, D. morri siana, D. lotus, D. glaucifolia, D. dumetorum, D. rhombifolia and D. susarticulata (cloth dye) are adopted for persimmon lacquer (kaki tannins) extraction. D. kaki, D. lotus, D. oleifera, D. rhombifolia, D. cathayensis and D. armata are wonderful ornamental plants (Fig. 3). Fig. 3 - Persimmon trees in Beijing street.

In recent years, a number of cultural events, such as persimmon festivals, have been celebrated in the main production area. The Gongcheng Yueshi (moon persimmon) Festival held by the Gongcheng Yao autonomous county, and the Mancheng Mopanshi Festival held in Mancheng county Hebei province are the most royal and are held annually attracting many tourists each year.

Cultural activities related to persimmon China is one of the origins of persimmon and has the longest cultivation history (Yu, 1979). Ever since ancient times, Japanese persimmon and Chinese people’s daily lives have been inseparable, as referred to some extent in all the previous dynasties writers’literature. There are many works of art related to Japanese persimmon, including poems, classical Chinese poems, songs, poetic essays, and legends (Wang, unpublished). At the same time, many place names are related to Japanese persimmon, such as Persimmon Forest County established in Shaanxi Province in the Yuan Dynasty. In addition, there are some works of art with Japanese persimmon as the theme. One example is a famous picture in which persimmons are described as jades (in Chinese, ‘persimmon’ and ‘thing’ are in uni- LATE WEI DYNASTY JIA SIXIE’s original work, MIAO QIYU emended and annotated, 1982 - Qi Min Yao Shu. - Agricultural Publishing House, Beijing, pp. 218-220.
