摘要
在水稻幼穗分化七期使用施用外源赤霉素,研究了赤霉素对水稻种子品质的影响。结果表明:外施赤霉素能降低水稻种子病害的发生与裂壳率,尤其是降低黑粉病的发病率,减少不育系制种的穗芽发生率及提高后代秧苗素质。赤霉素能使水稻种子的含糖量增加,更易遭鼠雀危害,并加速种子老化。
Exogenous applications of Gibberellin acid in the seventh stage of rice,researches were made on the influence of Gibberellin acid on the quality of rice seeds.Experiment results showed that exogenous applications of Gibberellin acid could reduce rice seed diseases and crack shell,decrease the incidence of Neovossia horrida,lessen the incidence of seed-heads buds of the sterile lines seed production,improve rice seedlings quality.But it also had adverse effect: GA could increase the seed sugar and more easier damaged by rat and finches,and could accelerate rice seed ageing.
