摘要:
以大通鸡腿葱为试材，分别于花后45、50、55、60、65 d采种，研究检测了不同采收期大通鸡腿葱种子的形态特征和内含物含量;研究了分级干燥处理并常温贮存1.5 a后,鸡腿葱种子的发芽活力进行了发芽试验。结果表明：随着鸡腿葱成熟度的提高，其种子饱满度增加；种子的含水量和可溶性糖含量随鸡腿葱成熟度提高有下降趋势;粗脂肪和可溶性蛋白质有升高趋势；不同成熟度鸡腿葱种子超干贮藏后发芽活力存在差异，种子在2.5%～3.5%含水量条件下的活力显著提高，花后45d采收的种子通过超干贮藏后可以大幅度提高种子活力，花后60d采收的种子更适宜超干贮藏。
Abstract:
Taking the seeds of ‘Datong’ Allium fistulosum that were harvested after anthesis 45,50,55,60,65 days as the test materials,the morphological characteristics and inclusions at different harvest time were dertermined,and germination vigor under different hierarchical dry moisture contents were detected and stored at ambient temperature for 1.5 years.The results showed that the seed plumpness increased alone with harvesting.The moisture content and soluble sugar content were downward trend,and the crude fat and the soluble protein content were upward trend with the increase of harvest time.There was different seed vigor between different maturities seeds in the ultra drying condition.The seed vigor of 2.5 to 3.5 percent water contents were higher than any others.The seed that picked after anthesis 45 days was stored in ultra drying condition,which seed vigor could be increased substantially.The seed that picked after anthesis 60 days was more suitable storage in ultra drying condition.
