摘要
本文对我国特有香花植物短丝木犀(Osmanthus serrulatus)种子的萌发特性进行了研究。结果表明:短丝木犀种子属于综合休眠,有生理后熟的现象,其果皮对其种子的吸水有阻碍作用;而通过变温层积环境可以有效打破其种子休眠,加快种子萌发。
The seed germination characteristics of Osmanthus serrulatus, an aromatic plant that endemic in China, were studied in this paper. The results showed that the dormancy of O. serrulatus was comprehensive and with the physiological after- ripping phenomenon; the peels hindered seeds water absorption; variable temperature stratification could effectively break seed dormancy and accelerate seed germination.
