Abstract

The salt-tolerant thresholds,germination percentages,germination time,photosynthetic rates and dry weights of Dekang961(DK961) and Lumai15(LU15) were examined under NaCl stress.The result showed that the salt-tolerant thresholds are 287 and 190 mmol/L NaCl for Dk961 and LU15 respectively,in certain scope and under different salt treatment.The photosynthetic rate of Dekang 961 is all higher than that of LU15.The germination percentages of both DK961 and LU15 decreased and germinative time was delayed,but the germination percentage and germinatrion time of LU15 were affected much more than that of DK 961 under same salt treatment.NaCl treatment caused a decrease in dry weight of wheat seedlings,and the degree of decrease was higher in LU15 than in DK961.
