摘要
以水曲柳种子为材料,探索药剂处理对种子层积催芽萌发的效果。结果表明:水曲柳种子层积处理前应用适当的外源激素处理会取得很好的效果;GA3在100 mg/L浓度时对提高种子萌发率有一定的效果;而BA则在1 mg/L浓度时对种胚的发育和种子萌发均有明显的促进作用;当使用GA3处理种子时,在低温或暖温层积前分别使用,可以获得较好的萌发效果。
Fraxinus mandshurica seed were selected as study meterial to discussed the effect of medicaments treatment on seed embryo growth and germination during seed stratification.The main results were as follows: dealing with proper plant growth regulators before seed stratification could get good pretreatment effect.Treating with 100 mg/L GA3 promoted the subsequent seed germination,but not the embryo growth,whereas treating with 1 mg/L BA promoted not only the embryo growth but also the subsequent seed germination.When treating Fraxinus mandshurica seed with GA3 for naked stratification,the methods for good germination are treating before cold stratification or treating before warm and cold stratification respectively.
