摘 要 ：在温室条件下研究了甘蓝蚜取食对结球甘蓝生长及叶球产量的影响。当甘蓝在莲座后期至结球初期被大量吸食后,绝大部分外叶卷曲变形,到结球中期外叶加外茎的重量及叶面积显著下降,但叶球的鲜重、干重及大小均未受到影响。蚜虫大量取食使甘蓝的叶球占全株的相对比重显著增加,同时也使叶球含水量略有上升。

Abstract:The influence of feeding by the cabbage aphid, Brevicoryne brassicae, on the growth and yield of the common cabbage was studied in a glasshouse experiment. When the plants were heavily infested by the aphid in precupping to early head formation stage, mos
