摘要: 研究了天然型脱落酸(S-ABA)和B、Zn、Mo3种微量元素浸种对红花大金元、NC82、云烟87和贵烟4号4种烤烟种子发芽势和发芽率的影响。结果表明,B、Zn、Mo3种微量元素能明显提高试验品种种子的发芽势和发芽率,而S-ABA对烤烟种子萌发有显著的抑制作用。Abstract: The effects of seed soaked with S-ABA, B, Zn and Mo on the germinating viability and percentage of tobacco seeds of cv. Hongda, NC82, Yunyan87 and Guiyan4 were studied. The results showed that the germinating viability and percentage of experimented tobacco seeds were evidently enhanced by B, Zn and Mo, while the germination of tobacco seeds was significantly inhibited by S-ABA.
