为研究芒(Miscanthus sinensis)种子的萌发特性,探究了不同温度、光照时间、土壤含水量和播种深度对芒种子萌发及幼苗生长的影响。结果表明,1)25℃为芒种子的最适萌发温度,低于10℃时,抑制其种子萌发及幼苗生长;2)光照时间对芒种子萌发率无影响,但对萌发指数、活力指数及幼苗生长有显著(P

In order to study the germination characteristics of Miscanthussinensisseeds,the influence of temperature,light time,soil water content and sowing depth on the seed germination and seedling growth were studied.The results indicated that the optimal temperature for M.sinensis seed germination was 25 ℃,and seed germination and seedling growth were inhibited under less than 10 ℃ treatment.The light time significantly influenced（P〈0.05）the germination index,vigor index and seedling growth,and the optimal light time was 12 halthough it had no e...
