seed stratification

Effects of different seed treatments including low temperature stratification, GA_3, CaCl_2 and KH_2PO_4 on aging seed physiological characteristics were studied with aging seed of Ephedra sinica stapf.

应用低温层积、GA3、CaCl2、KH2PO4处理人工老化处理的麻黄Ephedra sinica种子，研究不同处理对麻黄种子生理生化特性的影响。

The 180d low temperature stratification treatment and 120d naked stratification treatment are he best way to break seed dormancy.

本研究认为，低温沙藏层积处理180d和裸层积处理120d打破北美鹅掌楸种子休眠的效果最好，处理后的发芽率分别为88%和90%。

Through six months of low temperature stratification, ABA content of the external seed coat decreased 4.86 times and that of endosperm did 1.15 times, which that of either internal seed coat or embryo increased slightly.

经过低温层积6个月的种子外种皮ABA下降了4.86倍，胚乳为1.15倍，而内种皮和胚均有少量增加。

The effects of endocarp, seed-coat, GA3 and stratification on seed dormancy and germination were studied with wild cherry plum.

试验以野生樱桃李种子为材料，通过用机械去壳、去种皮、低温及赤霉素对野生樱桃李种子进行不同处理，研究了不同处理对野生樱桃李休眠及萌发的影响。
