- 摘要:
- 采用1 mol/L NaOH、72%的H2SO4、40℃高温、高湿和－20℃低温冷藏预处理，研究光照和黑暗的条件下商陆种子发芽率。结果表明：光照条件下种子的发芽率比黑暗条件下发芽率高；4种预处理均能提高商陆种子的发芽率，其中以72%H2SO4预处理效果最好。表明光可以促进商陆种子的萌发，种皮是商陆种子萌发的主要限制原因。
- Abstract:
- The germination percentages of pokeberry seed were studied after the pretreatment with 1 mol/L NaOH,72% H2SO4,high temperature and humidity with 40℃ and low temperature storage with -20℃ under dark or light.The results showed the germination percentages under light were higher than those of under dark.The germination percentages were all improved with 4 pretreatments and it had the hightest germination percentage with 72%H2SO4 pretreatment.Taking togther，light could promote germination of pokeberry seed and seed coat was a major limit factor to germination.
