Abstract

This study was conducted to investigate the effect of meteorological elements on the changes of inorganic nutrient contents in leaves of 'ruyu' and 'Nishimurawase' sweet persimmon during the growing season. The contents of N, P, K and Cu decreased in leaves of 'Fuyu' and 'Nishimurawase' sweet persimmon during vegetative growth, while Ca, Mg and Mn increased. The K content was higher in leaves of 'Fuyu' than in 'Nishimurawase' sweet persimmon. The P and Ca content was higher in 'Nishimurawase' leaves than in 'Fuyu' sweet persimmon. Mean temperature was positively correlated with content of P in leaves. Rainfall was positively correlated with the content of Ca in leaves, whereas it was negatively correlated with content of N and Cu in leaves. The duration of sunshine was positively correlated with N and Cu in leaves but negatively correlated with that of Ca, Mg, and Mn content.

본 연구는 동일 포장 내 부유와 서촌조생 품종의 잎 내 무기성분의 시기별 함량 변화와 기상요인을 조사하였다. '부유'와 '서초조생' 잎의 N, P, K, 및 Cu 함량은 후기로 갈수록 감소되었으나, Ca, Mg, 및 Mn 함량은 증가되었다. 그리고 '부유' 잎의 K함량은 서촌조생' 보다 높았으나, '서촌조생' 잎의 P와 Ca 함량은 '부유' 보다 높았다. 평균기온과 K 함량은 정의 상관이 인정되었다. 강우량은 Ca 함량과는 정의 상관이, N과 Cu 함량과는 부의 상관이 인정되었다. 그리고 일조량은 N과 Cu 함량과는 정의 상관이, Ca, Mg 및 Mn과는 부의 상관이 인정되었다.
