对不同贮藏和包装条件下大葱种子生理生化特性的研究结果表明：大葱种子随着贮藏时间的延长，其生活力降低，种子外渗液电导率和内含物的外渗量显著增加，发芽率和田间出苗率显著下降；电导率和内含物外渗量与种子发芽率、田间出苗率之间呈显著负相关。但主要种子贮藏物质与种子活力变化相关性不显著。种子的贮藏条件和包装方式对上述变化有一定的影响，低温低水和罐装的贮藏方式能延缓上述变化的速率，延长种子贮藏寿命。 The results of physiological and biochemical characteristics of Welsh Onion seeds under different storage and packaging conditions showed that with the prolongation of storage time, Welsh onion seedling decreased its viability and the conductivity and the extravasation of inclusions increased remarkably. The germination rate In the field, the emergence rate decreased significantly. There was a significant negative correlation between the conductivity and the content of extravasation and the seed germination rate and field emergence rate. However, the correlation between the storage of main seeds and seed vigor was insignificant. Seed storage conditions and packaging methods have some impact on the above changes, low temperature and low water and canned storage can delay the rate of change, to extend seed storage life.
