前言葡萄种子是由坚硬种皮包裹的有胚乳种子,完熟种子有休眠现象,通常为使之发芽,需在5℃条件下层积处理三个月.关于葡萄种子的休眠,以往已进行了打破完熟种子休眠方法的探讨和在层积处理过程中种子体内生长调节物质变化的研究.但是,还存在着葡萄种子的休眠是由发育的哪个阶段诱导的以及核和胚乳在此过程中起什么作用等很多未知问题.本试验就是为弄清种子和胚的休眠现象而进行的.
Introduction Grape seed is surrounded by a hard seed coat endosperm seed, mature seed dormancy phenomenon, usually to germinate, stratification treatment at 5 ℃ for three months on the grape seed dormancy has been carried out in the past to break the cooked Study on seed dormancy and study on the change of seed germplasm in the seed during stratification treatment.However, the stage of dormancy of grape seed is induced, and what role does nuclear and endosperm play in the process? Many unknown problems.This experiment is to find out the dormancy phenomenon of seeds and embryos.
