- 摘要:
- 以四川牡丹种子为试材,研究了不同温度层积处理对四川牡丹种子内部可溶性蛋白质含量和可溶性糖含量以及过氧化物酶活性等生理生化指标的影响。结果表明:低温层积对四川牡丹种子内部生理生化指标的影响不是十分显著;在打破四川牡丹种子的休眠,提高种子育苗发芽率时,应结合其它物理及化学方法进行。
- Abstract:
- Taking Paeonia decomposita seed as test material,the effects of different temperature stratification treatments on soluble protein and soluble sugar content and the activity of peroxidase physiology and biochemistry of Paeonia decomposita seed were studied.The results indicated that the effects of low temperature stratification treatment on physiological and biochemical characteristics of Paeonia decomposita seed was not very significant.It should be combined with other physical and chemical methods in breaking seed dormancy and improving seed germination rate.
