对紫薇、悬铃木、梓树和葛藤种子萌发特性研究结果表明,种子无休眠期,采收后在适宜条件下立即可以发芽。但每种的最适发芽条件不同,紫薇、梓树需在30℃昼/20℃夜,每日光照8小时,发芽率最高,分别为81%和96%。悬铃木需25℃昼/20℃夜,每日光照8小时,发芽率可达35%。而葛藤种子因硬粒多,除与紫薇等发芽条件相同外,还要反复用热水浸泡硬粒种子,发芽率可达21%。 The results of the germination characteristics of the seeds of Crape Myrtle, Platanus acerifolia, Catalpa bungei and Kudzu showed that the seeds could not germinate and could germinate immediately under appropriate conditions after harvesting. However, the optimum germination conditions were different for each species. The crape myrtle and Catalpa bungei had the highest germination rate of 81% and 96% at 30 ℃ day / 20 ℃ night and 8 day daily light. Platanus need 25 ℃ day / 20 ℃ night, daily light 8 hours, germination rate up to 35%. The kudzu seeds due to more than hard, in addition to the same germination conditions and crape myrtle, but also repeatedly soaked with hot water hard seeds, the germination rate of up to 21%.
