摘要
作者对芦笋果实成熟度，采种株株龄及贮藏年限与种子千粒重、发芽的关系进行了研究，并测定了不同贮藏年限种子的活力。结果表明：果实成熟度越好，所采种子千粒重、发芽势、发芽率也越高；后熟可提高这３项指标；成熟度越差，后熟效果越好，需要后熟的天数也越长。采种株株龄对发芽势的影响比对发芽率大；贮藏年限与活力指数呈极显著负相关，其相关系数为－０．９７；α－淀粉酶活性随贮藏年限增加而降低。
It was conducted that the relationship between weight of a thousandseeds,germination and plant age,fruit maturity were studied.The results showed thatthe more mature the seeds,the more high the weight of a thousand seeds,the germination patient,the rate of germination.The three indexes could be raised by rear ripe,Thelower the fruits maturity,the more obvious effects the rear ripe,and the more many dayswould be needed,plant age from which the seeds were collected effect smore in germ-nated patient that in germinated rates.there was a negative relations between seeds ageand vigor index,related coefficient-0.970.Activity of amylase was lowering as the rais-ing of seeds age.
