外源赤霉素对西洋参种子内源激素变化动态的影响
Affection of Exogenous Gibberellic Acid (GA3) on Endogenus Hormones of Panax quinguefolium Seed during Its Morphological Afterripening Period
【摘要】 文章通过分析外源赤霉素对西洋参种胚形态后熟过程中种内源 IAA、GA3、Z+ZH和 ABA变化动态的影响,指出外源赤霉素不能用来缩短西洋参种胚的形态后熟期,反而导致种子发育畸形;但可以用于生理后熟期以解除休眠。
【Abstract】 According to the determination of endogenus hormones variation of Panax quinquefoliwn seed during its morphological afterripenging period,and the affection of exo-GA3 on the endogenus hormones dynamics,it suggested that exo-GA3 couldn’ t be used for accelerate the growth of Panax quinquefolium embryo, but was helpful in relieving seed dormancy during physiological afterripening period.
