种子引发剂对辣椒种子发芽的影响

Effects of Seed Priming on Germination of Pepper Seeds

在30℃黑暗条件下,采用一定浓度的引发剂对3个辣椒品种进行引发处理,结果表明,100～500mg/L赤霉素(GA3)可以促进辣椒种子萌发,种子发芽势提高;10%～30%聚乙二醇(PEG)引发,兴蔬16号和福湘5号发芽势降低,福湘元春发芽势提高。由此可见,适量浓度的GA3提高辣椒种子发芽势。

Three varieties of pepper seeds （Xingshul6, Fuxiang5 and Fuxiangyuanchun） were treated with 2 kinds of initiators at 30℃ under dark conditions in order to select an effective way to enhance germination of pepper seeds. The results showed that pepper seeds germination percentage improved and germination potential inceased with 100-500 mg/ L of GA3 priming. Germination of Xingshu16 and Fuxiang5 reduced with 10%-30% of PEG priming, while germination of Fuxiangyuanchun increased. It can be concluded that GA3 of proper concentration would promote the germination of pepper seed.
