| Abstract: | 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... |
