摘要
种子老化是种子生活史的一个重要环节,具有生活力的种子在生理成熟期活力达到最高,之后种子活力降低。人工老化处理种子是当前人们最常用的模拟种子老化的一种技术。本文主要综述了人工老化处理对种子生理活性的影响,对内源激素、生理生化特性、遗传多样性等进行论述。并对人工老化种子的修复技术进行探讨,对未来人工老化处理种子及种子修复技术进行展望。
Seed aging is an important part of seed life history.Viable seeds reach the highest vigor in the physiological maturity period,and then the seed vigor decreases.Artificial aging of seeds is the most commonly used technology to simulate seed aging.This article mainly reviews the effects of artificial aging on the physiological activities of seeds,including endogenous hormones,physiological and biochemical characteristics,genetic diversity,etc.The restoration technology of artificially aged seeds is discussed,and the future artificially aged seeds and seed restoration techniques are prospected.
