- 摘要:
- 以紫楠、浙江楠种子为试材,通过采用不同的种子贮藏方式,设置不同的萌发温度和光照条件,对其种子萌发特性进行研究。结果表明:对于低温(4℃)湿砂层积和自然室温湿砂层积2种贮藏方式,紫楠、浙江楠种子的较佳贮藏方式是低温(4℃)湿砂层积。在15、20、25、30℃ 4个温度下,紫楠、浙江楠最适萌发温度均为25℃。在黑暗、12 h和24 h光照条件下,适宜的光照对紫楠、浙江楠种子萌发有一定的促进作用,但24 h/d的光照条件对浙江楠种子的萌发有一定的抑制作用。
- Abstract:
- Taking the seeds of Phoebe sheareri and phoebe chekiangensis as test maerials,the seed germination characteristics of Phoebe sheareri and Phoebe chekiangensis by experiment of different methods of seed storage(in wet stratified sand at 4℃,natural indoor temperature),germination temperatures(15,20,25,30℃) and lighting conditions(full dark,lighting 12 h and lighting 24 h)were studied.The results showed that the better storage method of the two seeds was in wet stratified sand at 4℃.The optimal temperature for germination of Phoebe sheareri and Phoebe chekiangensis was 25℃.Suitable light had positive effect on germination rate and energy,but decreased on 24 h lighting condition.
