Abstract:
The effect of NaCl stress on the characteristic of growth of 48 Medicago stiva L. germplasms were studied in the green house during the seedling stage. And the 4 growth indexes,such as survival rate,plant height,aboveground biomass and underground biomass,were measured and analyzed. The salt tolerance of different Medicago stiva L. germplasms were comprehensive evaluated by cluster analysis. The result showed that survival rate,plant height,biomass were significant decreased(P < 0. 05) with the increased of salt concentration,and 15 strong salt tolerance germplasms were screened out through comprehensive evaluation,such as ZXY05P-776,ZXY05P-1026,ZXY05P-1091,ZXY05P-1104,ZXY05P-1040,ZXY05P-785,ZXY05P-809,ZXY05P-857,ZXY05P-820,ZXY05P-1115,ZXY05P-1140,ZXY05P-1232,ZXY05P-1215,ZXY07P-3537.
