光温调控及氯化钠处理对千屈菜种子萌发的影响

Studies on Seed Germination of Lythrum salicaria with Controlling Illumination,Temperature and Treated by Sodium Chloride Solutions

用0(CK)、900、1 100、1 700、2 000 mg/L 5个浓度的氯化钠溶液处理千屈菜种子进行发芽试验。结果表明:随着浓度的升高,种子发芽率逐渐增强。方差分析表明,当浓度高于1 700mg/L后,种子的发芽率明显下降。千屈菜种子发芽期间变温处理的发芽率>固定温度条件下的发芽率;有光条件下的发芽率高于无光状况下的发芽率。

The seeds of Lythrum salicaria were treated by sodium chloride solutions of 900,1 100,1 700,2 000 . 0 （contrast,CK）mg/L, the results showed that the germination percent of seeds was escalating arcording with the density of sodium chloride solutions, and the germination percentage of seeds which treated by sodium chloride solutions of 1 700 mg/L would decreased obviously. During the seeds germination, the value of germination percentage which treated by change temperature was higher than that treated by unchanged temperature, and other way the value of germination pereentage with illumination was higher than that no illumination.
