Effects of NaCl stress on seed germination of Lycium ruthenicum Murr.

[Objective]To study the seeds germination of Lycium ruthenicum Murr.under different concentrations of NaCl,as well as to find the optimal concentration of NaCl for the germination of L.ruthenicum.[Method]The seeds of L.ruthenicum were treated with different concentrations of NaCl,and the state of seed germination was measured.[Result]With the increasing of concentration of NaCl,the seed germination rate of L.ruthenicum showed an obvious increasing trend.when the concentration was of 0.3%-0.4 %,the germination rate was the highest,and when the concentration of NaCl was greater than 0.4,the germination rate showed a decline trend.[Conclusion]After treated with appropriate concentrations of NaCl before sowing,the germination rate of seeds of L.ruthenicum would increase.
