【摘要】 [目的]检测山杜英种子品质及种子发芽势，筛选优良种质，提高山杜英在园林和经济方面的利用率。[方法]以台山市红岭种子园提供的山杜英种子作为试验材料，从山杜英种子的优良程度、含水量、生活力3个方面进行了品质检验试验，并通过不同浓度的赤霉素(GA)对山杜英种子进行催芽处理，比较其发芽率、发芽势与常温水浸处理(CK)的差别。[结果]山杜英种子品质优良，含水量为23.46%,平均生活力为80%,经过600 mg/L GA浸泡的种子发芽率及发芽势有明显提升，与CK相比发芽率提高18.75百分点，发芽势提高10.75百分点。[结论]GA浸种对山杜英种子发芽有一定促进作用。更多还原

【Abstract】 [Objective]In order to detect the seed quality and seed germination potential of Elaeocarpus sylvestris,screen excellent germplasm, and improve the utilization rate of Elaeocarpus sylvestris in landscape and economy.[Method]Taking the seeds of Elaeocarpus sylvestris provided by Hongling Seed Garden in Taishan City as materials, the quality inspection experiment was carried out from the three aspects of the quality, water content and viability of Elaeocarpus sylvestris seeds, and the germination rate, germination potential and the difference between normal temperature water immersion treatment were compared at the germination site of Elaeocarpus sylvestris seeds with different concentrations of GA.[Result] The quality of the seeds was excellent, the water content was 23.46%,and the average viability was 80%.The germination rate and germination potential of the seeds soaked with 600 mg/L GA increased significantly, compared with CK,the germination rate increased by 18.75%,and the germination potential increased by 10.75%.[Conclusion] GA soaking has a certain promoting effect on the germination of Elaeocarpus sylvestris seeds.更多还原
