摘要
用不同浓度的GA3溶液分别对东方百合种球进行浸泡,并结合冷藏处理,研究外施GA3对种球碳水化合物代谢和内源激素平衡的影响。结果表明:在解除休眠的过程中,GA3始终保持着高浓度,ZR则相反;可溶性总糖、IAA、GA3、ZR均比冷藏初始期浓度增高,淀粉、ABA则下降。经相关分析得到各种处理的GA3与GA3/IAA比值存在极显著相关;与其它激素和激素比值之间无显著相关性。初步判定百合解除休眠与外界条件变化有关,如低温刺激,而与增加GA3浓度无关。
By soaking Oriental Lilium siberia seed balls with GA3 solutions of different concentration, combined with cold storage, the effects of external gibberellins on bulb carbohydrate metabolism and endogenous hormone balance were studied. The results showed that the concentration of GA3 was high all long during the process of breaking dormancy, ZR was opposite; the concentration of soluble total sugar, IAA, GA3 and ZR were all higher than cold storage in initial stage, and starch and ABA were decreased. By correlation analysis indicated that GA3 of different treatments were significant correlation with GA3/IAA, and no significant correlation with other hormones and ratios of GA3 and other hormones. And obtained preliminary that breaking dormancy of Lilium siberia was correlation with change of external conditions, such as low temperature stimulating, was not correlation with increasing of the concentration of GA3.
