Effect of Salt Stress on Rice Seedling Characteristics——Effect of Salt Stress on Root System at Seedling Stage of Rice

The reaction of root growth to salt was studied through a germination experiment conducted by soaking 123 rice seeds in pure water,100 mmol/L NaCl and 150 mmol/L NaCl solutions.The result showed that with the increase of salt concentration,the mean root numbers and mean root length per plant decreased obviously and the data distributed continuously indicating that the genotype difference is one of the screening basis for salt-tolerance rice germplasm.
