细黄链霉菌与氮磷钾肥配施对桔梗幼苗的影响
Effect of the Streptomyces microflavus and NPK Fertilizer on Platycodon grandiflorus Seedlings
摘要
Abstract
Platycodon grandiflorus seeds were used as materials. The physiological indexes of P. grandiflorus seedlings and correlations were analyzed with different concentrations of Streptomyces microflavus and NPK fertilizer. Results showed that the CAT activities, POD activities and soluble protein contents of P. grandiflo-rus were increased with different concentrations of Streptomyces microflavus and NPK fertilizer (the optimum concentration of S. microflavus was 50 times.),while the contents of MDA were reduced (the optimal concen-tration of S. microflavus was 20 times.). By correlation analysis, POD activities had positive correlation with protein contents and CAT activities,and their differences were highly significant (P＜0.001). Protein con-tents had positive correlation with CAT activities, and their differences were extremely significant (P＜0.01) .关键词
