硝酸镧对高粱老化种子萌发活力的影响

Effect of Lanthanum on Aged Seed Germination of Sorghum

文章研究硝酸镧浸种对自然老化高粱种子发芽的影响.结果表明经硝酸镧处理后,部分处理的老化种子的发芽率、发芽指数及活力指数都明显提高,呼吸作用增强,种子浸泡液电导率下降.实验用0 mg/L^70 mg/L的硝酸镧处理高粱种子,其中以60 mg/L的处理效果最佳.

The effect of La on nature aged seed vigor of sorghum was study by experiment. The result showed that germination rate ,germination index and vigor index of nature aged seeds of sorghum were increased with La（NO3）3 trea and reduce cell membrane permeability of sorghum seeds i was soaked in La （NO3）3 solution with concentrations treatment with 60 mg/L was recommendable. tments. It could increase respiration rate in germination stage. The sorghum seeds from 0 mg/L ～ 70 mg/L. The soaking
