| 中文摘要: |
| 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 mg/g GA3浸种对番茄幼苗的生长有一定的促进作用。 |
| 英文摘要: |
| 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 concentration of 120 mg/g decreased obviously tomato seed's germination rate, germination index, seedling height and root length. Different concentration's polyethylene glycol decreased obviously the seedling chlorophyll content. Soaking seeds with GA3 with the concentration of 50 mg/g increased obviously tomato seed's germination rate, germination index, seedling height, root length and chlorophyll content under polyethylene glycol stress. So soaking seeds with 50 mg/g GA3 promotes tomato seedling's growth. |
