| 摘要: |
| 未经层积处理的桃种子用赤霉素(GA)处理,或去掉种皮,可以有效地解除种子的休眠,促进种子的萌发。试验不仅进一步揭示了种皮对桃种子萌发的抑制作用,而且还揭示了种皮的抑制作用主要不是机械阻力,而是化学抑制物质的作用。试验还表明,经 GA 和去种皮处理的种子,萌发后在露地均能正常生长发育。这一试验结果为提早播种育苗,缩短育苗和育种年限提供了一个有效的途径。 |

| Abstract: |
| Treatment with removing seed coat and gibberellic acid(GA)can be effectively breakdown dormancy Of non-stralified peach seed and stimu- late it germination.Various treatments revealed a inhibitive role of seed coat on peach seed germination.This role is not mechanical resistance to germinatoin but chemical inhibitor.The experiment shows that seeds treating with GA and removed seed coat can normally grow and deve- lop in field after germination.The result provides a effective way to ea- rly seed and shorten ... |
