| 摘 要： | 以番茄幼苗为材料,研究了50 mg/g 的赤霉素(GA3)和清水浸种后用不同浓度的聚乙二醇(0、40、80、120 mg/g)胁迫对番茄种子萌发及幼苗生长的影响.结果表明:40 mg/g的聚乙二醇胁迫对番茄种子的萌发率、发芽指数、幼苗株高、根长有促进作用,120 mg/g的聚乙二醇明显抑制种子的萌发率、发芽指数、幼苗株高、根长;不同浓度的聚乙二醇胁迫明显降低了幼苗的叶绿素含量.用50 mg/g GA3浸种后明显增加聚乙二醇胁迫下番茄种子的萌发率、发芽指数、幼苗株高、根长和叶绿素含量.用50 m g/g GA3浸种对番茄幼苗的生长有一定的促进作用.

| Abstract: | The tomato seedlings were used as experimental materials,and the effects of seed soaking with Gibberellic Acid(GA3) with the concentration of 50 mg/g and tap water with the different concentrations polyethylene glycol(0,40,80,120 mg/g) stress on the germination and seedling growth of tomato were investigated.The result showed that polyethylene glycol with the concentration of 40 mg/g increased tomato seed's germination rate,germination index,seedling height and root length,while polyethylene glycol with the... |
