主 题：Taxus chinensis var.mairei Piriformospora indica water stress respiration
摘 要：Seedlings of Taxus chinensis *** were used as experimental materials to study the adaptation of Piriformospora indica to this plant under water *** materials were divided into two groups,namely,with or without inoculation with *** group was subjected to four different levels of water *** and physiological and biochemical indexes of the roots of *** *** were regularly *** water stress,*** *** had significantly decreased root vitality;root vitality was higher in inoculated roots than in uninoculated *** intense water stress,the inoculated roots had a higher soluble sugar content than the uninoculated *** water stress,*** *** experienced decreased activity of aerobic respiratory metabolic *** activity of anaerobic respiratory metabolic enzymes and alcohol dehydrogenase initially increased and then decreased,whereas that of lactate dehydrogenase *** inoculated roots had a higher activity of respiratory metabolic enzymes than the uninoculated *** water stress was further intensified,the roots had significantly decreased activity of aerobic respiratory metabolic enzymes and significantly increased activity of anaerobic respiratory metabolic *** activity of respiratory metabolic enzymes decreased faster in the uninoculated roots than in the inoculated *** study demonstrated that Piriformospora indica plays a positive role in enhancing the antihypoxic ability of *** ***,thereby alleviating plant damage due to water stress.
