Optimal time of seed cold stratification for Pinus tabulaeformis;
油松种子最佳低温层积时间的探究
hexandrum seed,some methods such as isolated embryo cultures,biological identification,soaking seed in GA3,interaction GA3 and cold stratification were utilized.
桃儿七种子在自然条件下具有休眠期长、萌发不良的生理特性,为了探讨和研究桃儿七种子的休眠特性,利用分离胚培养、生物鉴定法、GA3浸种、以及综合利用GA3和低温层积处理等方法。
Though GA_3 plays a positive role on breaking dormancy,its effectiveness is not as good as cold stratification.
结果表明:油松种胚具有休眠特性,种子属于中度休眠特性的种子,且不同种粒之间休眠深浅有差异;赤霉素对解除油松种胚休眠也有一定作用,但效果不及低温层积处理,经过低温层积的种子没必要再用赤霉素来解除胚休眠。
