因种子的胚及胚乳具有很强的吸湿性,在贮存及运输过程中极易吸收水分,并在高温条件下易发热霉变,在低温条件下易发生冻害,而失去发芽能力。所以如何保证优良品种的安全贮存,确保良种的芽率、芽势、延长良种在生产上的使用年限,应主要做好以下几方面工作。
Due to the seed embryo and endosperm has a strong hygroscopicity, in the process of storage and transport easily absorbed moisture, and in the high temperature easy to mold fever, cold conditions prone to freeze damage, and lost the ability to germinate. Therefore, how to ensure the safe storage of fine varieties, ensure the germination rate of buds, buds, and extend the useful life of fine varieties in production should mainly do the following aspects.
