Compared with results from the conventional thinning method (CTM), the percentage of old leaves was lower and that of summer leaves was higher in the trees cultivated in the off-year with the IABS. The IABS leaf/fruit ratio was 14.8, statistically lower than that for the CTM (43.3). Compared with that of new leaves, the photosynthetic and transpiration rate of old leaves in IABS-cultivated trees was about 40% lower. There was no difference in photosynthetic and transpiration rate of new leaves among the treatments. The photosynthetic and transpiration rate of new leaves reached its maximum value in September of 2001 and July of 2003. Compared with those of the CTM, the leaves of trees cultivated with the IABS had deep greenness in the on-year and thin greenness in the offyear. The amount of fibrous roots increased after the year all fruit was thinned.}, pages = {99--107}, title = {樹別隔年交互結実栽培を行ったウンシュウミカン成木における光合成・蒸散速度と葉色の推移}, volume = {9}, year = {2010}, yomi = {タキシタ, フミタカ and ウチダ, マコト and ヒラオカ, キヨシ} }
