- 摘要:
- 以桃叶杜鹃种子为试材，对其进行千粒重、含水量、吸水率及种皮抑制物质的测定，研究了不同培养温度对种子萌发的影响、不同温度+浸种处理和不同的贮藏方式对桃叶杜鹃种子的发芽率和发芽势等萌发特性的影响。结果表明：桃叶杜鹃种子细小，千粒重仅为0.319 g。种子含水量较低，仅有10.24%。种皮透水性良好，种皮没有抑制种子萌发的物质。恒温有利于种子的萌发。以赤霉素处理、在25℃萌发对桃叶杜鹃种子较好。桃叶杜鹃种子经贮藏后发芽势提高较大，且与室温贮藏相比，低温密封保存较好。
- Abstract:
- Taking the seeds of Rhododendron annae Franch as test materials，the 1000-grain weight，moisture content，water absorption and the inhibiting substance of testa were measured，the effect of germination rate and germination potential of Rhododendron annae Franch seeds at different temperatures，different temperature+different soaking treatments and different storage methods were studied.The results showed that the 1000-grain weight of Rhododendron annae Franch seeds was very light，only 0.319 g；the seed moisture content was low，only 10.24%.The testa permeability of seeds was good，and there was no material inhibiting seed germination in testa.The constant temperature was conductive to seed germination.The seed germination with gibberellin treatment and at 25℃ was better than others for Rhododendron annae Franch seeds；the seed germination potential of Rhododendron annae Franch was greatly improved after storage，and compared with storage at room temperature，the low temperature sealing preservation was better.
