Effect of NaCl stress on the physiological characteristics of Puccinellia tenuiflora cv.Tongde

ZHOU Xue-li1,ZHOU Qing-ping2,YAN Hong-bo2,LU Su-jin1(1.Qinhai University,Xining 810016,China;2.Qinghai Academy of Animal Science and Veterinary Medicine,Xining 810016,China)  
The salt tolerance of Puccinellia tenuiflora cv.Tongde seedling under different NaCl treatments(0,0.2%,0.4%,0.6%,0.8%,1.0%,1.2% and 1.4%) was identified by determining the physiological indices.The results showed that the contents of RWS and MDA decreased with NaCl concentration increasing,and the difference of RWS or MDA contents was significant among treatments.The contents of chlorophyll,soluble protein and proline increased with the increasing of salt concentration and the difference between the lower NaCl treatments and CK was not significant,however,tit was significant between the higher NaCl treatments and CK.This suggested that P.tenuiflora cv.Tongde was salt-tolerant and could be extended in salinity soil.
