杉苗被矮化线虫侵染后,叶绿素含量、根活力、净光合速率等生理生化指标均比健康植株低,而呼吸速率、过氧化物酶活性、蛋白质含量、酶比活力等指标则比健康植株高。说明感病杉苗生长衰退、严重矮化与矮化线虫侵染根部后、直接或间接地干扰了体内一系列的生理代谢过程有密切的关系。 Phyllostachys nivalis infected by dwarfing nematode, the chlorophyll content, root vigor, net photosynthetic rate and other physiological and biochemical indicators than healthy plants, and respiration rate, peroxidase activity, protein content, enzyme activity than other indicators of health Plant height. The results showed that the growth of Sophorae blossoms declined, severely dwarfed and dwarfing nematodes invaded the roots, directly or indirectly interfere with a series of physiological metabolic processes in vivo are closely related.
