以珍稀趣味药用植物跳舞草(Codariocalyx motorius)为材料,通过机械磨擦、不同温度、光照强度和GA_3处理以及不同栽培介质研究了其种子萌发特性,以寻找其繁殖环节中的主要限制因素,为迁地保育和大规模育苗提供可行依据.结果表明:机械磨擦可使跳舞草种子的发芽势、发芽率及发芽指数显著提高,种子种皮的机械抑制是导致其发芽率低的直接原因;其种子萌发的适宜温度范围20～30℃,25℃为最适温度;浓度为50～100 mg/L的GA_3处理的跳舞草种子萌发率高,且出苗整齐,根系粗壮,成苗率高;适度的遮光(30%)对跳舞草种子的萌发有促进作用,其发芽势、发芽率以及发芽指数最高;跳舞草的育苗基质可选用腐叶土:泥炭(1∶1),出苗率达到85.9%,经济合理.

Codariocalyx motorius is a rare interesting and medical species.To explore the underlying mechanisms relevant to the impediment in its sexual reproduction,and to provide the suit foundation for ex situ conservation and large-scale grow seedlings,we studied the effects and characteristics on germination of C.motorius seeds under the mechanical scarification,different temperature,light,GA_3 and substrate.The results showed that mechanical friction made the C.motorius seeds a remarkably higher germinating energy,germination percentage and germinating index.Thus it followed that the mechanical inhibition resulting from the testa of C.motorius seeds was the direct reason why C.motorius seeds germinated at a low rate.Results showed that the optimum temperature was 25℃ and range was 20～30℃ for the germination of C.motorius seeds.In the 50～100 mg/L GA_3,the germination percentage is higher,and the seedlings come out evenly,root system sturdy.In 30% sunshade percentage,germination speeds became quickly,and the germinating energy,germination percentage and germinating index is the highest.The substrate humus+peat (1∶1) was favorable for the germination of C.motorius seeds with seedling emergence rate reaching 85.9%.The germination method is economical and reasonable.
