Response of Dry Matter Accumulation and Chlorophyll Fluorescence Parameters of Haloxylon ammodendron Seedlings to NaCl Stress
梭梭幼苗干物质积累和叶绿素荧光对NaCl胁迫的响应

In this paper,the response of chlorophyll fluorescence parameters and dry matter weight of H.ammodendron,a typical species distributed in arid desert of northwestern China,to NaCl stress was investigated.In 30 days after NaCl stress,the dry matter weight of stems,leaves and roots,and the leaf number all decreased along with increase of salt concentration;in 50 days after NaCl stress,the dry matter weight and the leaf number showed no decrease trend along with increase of salt concentration,and the dry matte...
