不同浓度NaCl胁迫对黑果枸杞种子萌发的影响（摘要）

[目的]研究黑果枸杞种子在不同浓度NaCl溶液中的萌发情况,并探明黑果枸杞萌发的最适NaCl浓度。[方法]用不同浓度的NaCl溶液对黑果枸杞种子进行盐胁迫处理,测定种子的萌发情况。[结果]随着浓度的增大,黑果枸杞种子萌发的数目逐渐增多,在NaCl浓度为0.3%～0.4%之间时黑果枸杞种子的萌发情况最好,随后随着浓度的增大萌发数逐渐减少。[结论]生产实践中,播种前对种子进行适当的NaCl胁迫处理,可能会提高种子的萌发率或成活率。

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.
