摘要
通过不同质量浓度赤霉素对玉米种子进行处理,对其发芽比率、发芽指数、活力指数等萌发特性指标,胚根长、胚芽长等形态指标以及可溶性糖以及丙二醛等生理指标进行测定。结果表明:当赤霉素质量浓度为100~500 mg/L时,其对玉米种子萌发及生理代谢均具有一定的促进作用,除根芽比外,各项指标均呈先上升后下降的趋势;总体而言,当赤霉素质量浓度400 mg/L时,其作用效果最为明显,能够在一定程度上促进玉米种子早生、快发,有利于苗齐、苗全,为高产、稳产奠定坚实的基础。
Maize seeds were treated with gibberellin at different mass concentrations.Germination characteristics,such as germination ratio,germination index and vigor index,morphological indexes,such as radicle length and germ length,and physiological indexes,such as soluble sugar and malondialdehyde,were determined.The results showed that when the concentration of GAwas 100-500 mg/L,it had a certain promotion effect on the germination and physiological metabolism of maize seeds,and all indexes showed a trend of increasing first and then decreasing,except the root to shoot ratio.In general,when the mass concentration of GAwas 400 mg/L,the effect of GAwas the most obvious,which could promote the early growth and rapid growth of maize seeds to a certain extent,which was conducive to the uniformity and integrity of maize seeds,and lay a solid foundation for high and stable yield.
