Abstract
Japanese persimmon ( ) is a delicious fruit tree. It is grown relatively warm areas (<1500 m asl) of Gilgit Baltistan. Around four million tons are produced globally. China, being major producer contributes almost 80% followed by Korea and Japan (0.4 and 0.2 million tons) respectively. Asian countries collectively produce 95% of the total worldwide production. There is no record of persimmon production is available from Pakistan. However, Gilgit-Baltistan has the highest production followed by Swat. Study conducted in district Gilgit revealed that it has least contribution into local economy. Fruit is harvested in October to December. Mature plant produces an average of 151.8kg (Std. Dev.103.58749) annually. Sixty-four percent is sold for a mean price of 13.2 (Std. Dev.6.62) Pak rupees per kilogram. Mean household consumption was 25.65kg (Std. Dev.25.52). Mean DBH of 78.59cm (Std. Dev. 54.5136) and 20 ft high. Average life span estimate was 59.3-year (Std. Dev. 27.57198). Contrary to several medicinal uses in the world, people (>98%) in the area never use it as medicine except some rare use for skin fairness and improving blood circulation (<2%). About 80% trees flower as early as in April, fruiting starts in May (82%) and 84% harvested in November. Majority population (78%) is disease free. Around 78% farmers believe that it requires low water and fertilization. Mean leaf size was 257.52cm 2 (length 11.57cm, width 22.2cm). Ten leaves have a mean weight of 0.82g. Mean fruit height recorded was 4.2cm, diameter 6.0cm and weight 121.4g. Three varieties exist in the area. Dendrogram constructed using Hierarchical clustering showed that use of leave and fruit quantitative morphological characters cannot be used towards any discrimination and taxonomic classification. There is no selective breeding nor any value chain development programmes to improve depreciating gene pool in changing climatic conditions. Besides, its promotional efforts, detailed investigations are required to document biochemical, molecular and morphological markers.
