摘　　要：番茄叶片被番茄刺皮瘿螨危害后,一些生理生化指标发生了变化。与对照相比叶绿素、可溶性糖含量下降,螨量大和危害时间长则下降速度快。少量瘿螨在短时间内危害导致可溶性蛋白质和游离氨基酸含量上升,且随着螨量增加和危害时间的延长含量增加,而危害时间过长,其含量则下降。对于游离脯氨酸,则是螨量大,危害时间长其含量增加快。危害期为6d,处理20头/叶与60头/叶的游离脯氨酸含量分别比对照增加31.7887%、82.0439%。Several physiological and biochemical indexes of tomato leaves injured by Aculops lycopersici were measured. Compared with the normal leaves, the content of chlorophyll, soluble sugar of tomato leaves damaged by Aculops lycopersici decreased as the time prolonging and the amount of mite increasing. Contents of soluble protein and free amino acid of the tomato leaves rose when they were injured by little mites in short time. And that, as the time prolonging and the amount of mite increasing both the contents increased. The content of free proline of treatment 20 amount per leaf and 60 amount per leaf increased rapidly respectively by 31. 7887% and 82. 0439% in six days compared with the normal leaves.
