- 摘要:
- 以太白杜鹃种子为试材，研究了不同光照时间、不同浓度赤霉素（GA3）浸种处理对种子萌发的影响，以期为太白杜鹃的种质保存和开发利用提供科学依据。结果表明：光照时间对太白杜鹃的发芽时间和发芽率均没有明显的影响，但在24 h全黑暗状态下，在GA3浓度低于800 mg/L时，其发芽势要高于另外2种光照处理；用GA3对太白杜鹃种子进行24 h浸泡后，可以显著提早太白杜鹃种子开始发芽时间，缩短种子萌发的时间，提高其发芽率和发芽势。
- Abstract:
- Taking Rhododendron purdomii seed as material,the effects of light time and gibberellin(GA3) on Rhododendron purdomii seeds germination were studied,in order to provid a scientific basis for germplasm preservation and utilization of ?Rhododendron purdomii.The results showed there was little difference among the three light time on the starting germination time，germination rate，but under 800 mg/L GA3 conditions，the germination vigor of 24 h dark was much higher than the other two light treatments.After soaked 24 h with different concentration GA3，the starting germination time，germination rate and germination vigor were all dramatically enhanced.
