摘要:
6-磷酸海藻糖(T6P)对植物生长发育具有调控作用，然而T6P对大豆农艺性状的影响尚不明确，阐明T6P对大豆生长发育的影响，可丰富T6P的作用机制，并为大豆高产育种提供指导。以通豆13 (粒用大豆) 和通豆6号 (菜用大豆)为试验材料，以清水和常规药剂为对照，采用T6P拌种和茎叶喷施2种方式，设置不同浓度处理，揭示其对大豆萌发、籽粒产量、蛋白质含量、油脂含量和激素含量的影响。结果表明，T6P拌种处理可显著提升大豆的发芽势、发芽率和发芽指数，在1 kg种子/10 g药剂处理时，增益效果最显著。T6P拌种和茎叶喷施均能增加粒用大豆的荚数、粒数、株高和有效分枝数，提高小区产量，其中2% T6P 4 g/667 m2处理下总体增益效果最显著。而茎叶喷施T6P对大豆蛋白质、油脂含量等品质性状影响不大。此外，T6P拌种处理可显著提高苗期大豆根和茎中水杨酸、吲哚-3-丙酮酸、12-氧代植物二烯酸和赤霉素20等植物激素的含量。整体而言，T6P拌种和茎叶喷施均能提高粒用大豆的产量相关性状。对菜用大豆进行T6P拌种处理，20 g/667 m2处理下，菜用大豆的每株鲜重、每株鲜荚重和小区荚重显著增加，4 g/667 m2处理下菜用大豆的底荚高度显著降低，在2种浓度处理下，菜用大豆株高和有效分枝数均显著提高。
