在板栗（Castanea sativa Mill.）CV. Santa Restituta，在完全开花后10天，对完全暴露于阳光下的环带和未环带的枝条进行落叶以得到2/1、4/1、7/1、10/1和14/1的叶壳比。结果表明，果实的同化物容易转移，每果壳需有10片左右的叶片（每果约5片叶片）才能保证果实的正常发育。果实是一个比芽储备组织更强的库。在高叶壳比光合作用的反馈抑制建议。# 2000 Elsevier Science B. V.保留所有权利。
In Castanea sativa Mill. cv. Santa Restituta, 10 days after full bloom, defoliation to give leaf-tohusk ratios of 2/1, 4/1, 7/1, 10/1 and 14/1 was performed on both girdled and ungirdled shoots fully exposed to the sun. The results showed that assimilates can be easily translocated and it is necessary to have about 10 leaves well exposed to light per husk (about ®ve leaves per fruit) to ensure normal fruit development. Fruit is a stronger sink than shoot reserve tissues. A feedback inhibition of photosynthesis at high leaf-to-husk ratios is suggested. # 2000 Elsevier Science B.V. All rights reserved.
