AV. Vassil, Zelkova serrata(ibinb.) Makino and Magnolia kobus DC. in the Kasuya Research Forest, Kyushu University.We analyzed the patterns of foliation and defoliation using the image pictures taken from the ground.the foliation of Z. serrate and the defoliation of a Q, serrate tree were later than the other trees.the temperature dependence of foliation was larger than that of defoliation for all trees.the defoliation was affected by strong winds other than temperature. C. x yedoensis and M. kobus showed larger temperature dependence of the foliation comparing with Q, serrata and Z. serrata. Keywords : cumulative temperature, defoliation, foliation, logistic curve, temperature dependence 1.
