摘要
目的:研究野生万寿竹种子的萌发特性,明确种子适宜萌发条件。方法:以野生万寿竹种子为试验材料,测定了万寿竹种子的吸水率,采用培养皿发芽法,比较了不同培养温度(15℃、20℃、25℃、30℃)、光照和暗黑、纸上和纸间发芽床条件、去种皮与不去种皮的种子前处理对万寿竹种子萌发的影响,测定其萌发率,观察萌发动态。结果:种子千粒重为33.24 g;种子吸水在30 h达到了饱和状态,吸水量为96.90%;种子用萌发处理剂浸泡24 h,培养在25℃、纸间发芽床、黑暗条件下萌发率较高。结论:不去种皮,萌发处理剂浸种24 h,在25℃黑暗条件下进行纸间培养是万寿竹种子萌发的最适条件。
Objective ： To study the seed germination characteristic and optimal germination condition of wild Disporum cantoniense. Methods ： Used wild Disporum cantoniense seed as the test materials, the rate of water absorption of the seed was determined. The ger- mination rates under different conditions, along a temperature gradient （ 15,20,25 and 30℃ ）, in light or dark, on top or between wet filter papers, and keeping or removing the seed coat, were determined respectively using petri dish method. At the same time germina- tion trends were observed. Results： The thousand seed weight was 33.24 g, and the seed water-absorbing reached saturation pot after soaking for 30 h. Higher germination rates were respectively recorded at 25℃, between filter papers, and in dark after 24 h soaking in the pretreatment solution. Conclusion ： The optimal condition for the germination of the seed of wild Disporura cantoniense is as follow： keeping testa, seed soaking for 24 h in seed germination agent and being incubated between wet filter papers in dark at 25 ℃.
