摘　　要：研究返青成活期、瘤茎膨大始期和盛期茎瘤芥叶片受损对其主要经济性状的影响,结果表明:在试验范围内,叶面损伤对茎瘤芥瘤茎形状、茎瘤芥产量、植株大小等有影响且规律性明显;叶片受损程度越大,受损时间越迟,影响越大。完全展开的叶片受损后对茎瘤芥主要经济性状的影响要低于未完全展开的叶片,完全展开叶全部受损后,未完全展开叶再受损影响更大,而且随着叶片受损程度的加重和时间的推迟影响增大。Effects of extent of damaged leaves to main economical characters of tumorous stem mustard during regreen period, early period and flourishing period of development of expand of tumorous stem were studied at Fuling. The results show that foliar loss affect tumorous stem shape and the yield of tumorous stem mustard, plant size and so on with obviously regularity. The larger and later that leaves were damaged, the influence bigger. Effects of fully expanded leaves damage to main economical characters of tumorous stem mustard was below that of incomplete expanded leaves damage. If incomplete expanded leaves were damaged again after fully expanded leaves damage, the effects were bigger, moreover, increased with the increase of damage degree and time.
