摘要
玉米 (ZeamaysL .)果穗的结实能力与籽粒产量密切相关 ,而花丝本身的营养状况可能会对花丝活力及其感受力产生一定影响。本文就近年来有关花丝和穗轴中的有机营养 (可溶性糖、淀粉、氨基酸、蛋白质 )和矿质养分 (氮、磷、钾、钙、镁、硫、铁、锰、铜、锌等 )的变化动态及其对花丝活力和果穗结实能力的可能影响进行了综述 ,以期找出影响玉米授粉结实的原因 。
Seed site ability has a great effect on maize yield, and the contents of organic nutrition and mineral elements may have certain effects on silk activity and seed site ability. This paper is a brief review of dynamic of organic nutrition (soluble sugar, starch, amino acid, protein) and mineral elements (nitrogen, phosphorus, potassium, calcium, magnesium, sulphur, iron, manganese, copper, zinc,etc.) in silk and cob of maize and its effect on silk ability and seed site ability from previous studies in recent years. Through the review, the reason that affects the pollination is expected to find and then the theoretic gist is provided for higher seed site ability.
