Effects of Exogenous Tryptophan on C/N Balance and Senescence Characteristics of Sorghum Seedlings Under Low Nitrogen Stress

[Objective]The purpose of this study was to investigate the effects of exogenous tryptophan on senescence of sorghum(Sorghum bicolor L.)seedling leaves under low nitrogen stress,and to explore the relationship between C/N balance and senescence of sorghum seedlings leaves,so as to provide effective regulation means for sorghum resistance to low nitrogen stress.[Method]In a hydroponic culture experiment,the low nitrogen tolerance sorghum line(398B)and the low…查看全部>>
