다국어 초록 (Multilingual Abstract)

This experiment was carried out to investigate the effects of foliar spray of liquid calcium fertilizer and CaCO3 during the growing season on mineral nutrients, fruit quality and physiological disorder of non-astringent persimmon. Calcium contents of leaf, fruit flesh and peel were increased by foliar spray of liquid calcium fertilizer manufactured from oyster shell, but CaCO3 foliar spray had no effect. In persimmon treated both chemicals, K contents of leaves were decreased and those of flesh were increased, but those of peel not changed. The contents of T-N, P, and Mg in all investigating parts were not affected with treatment. The fruit firmness of persimmons treated with liquid calcium fertilizer was higher than that of other fruits at harvest and after 56 days of storage at 25℃. The rates induced skin blackening and green spot fruits were decreased by foliar spray of liquid calcium fertilizer. The Ca contents in leaf and peel of persimmons induced green spot fruits were lower than those of normal persimmons, but the Mn contents were higher.
