摘要
以含笑(Michelia figo)花粉为试验材料,采用花粉人工培养法研究了含笑花粉离体萌发的最适条件。结果表明:蔗糖、硼酸在一定浓度范围内能促进花粉萌发,含笑花粉萌发的最适蔗糖和硼酸分别为50 mg.L-1和5mg.L-1,萌发率分别为21.51%和44.14%;花粉最佳萌发温度为25℃,萌发率达53.33%。正交试验设计结果表明,花粉萌发的最佳组合为70 mg.L-1蔗糖+5 mg.L-1硼酸+28℃,萌发率可达65.33%。
The suitable germinating media and optimized temperature for Michelia figo pollen were studied.The results showed that： the optimal concentration of sucrose and boric acid for germination of Michelia figo pollen were sucrose 50 mg·L-1 and boric acid 5 mg·L-1,the pollen germination reached 21.51% and 44.14% respectively.The optimized temperature was 25℃,the optiminal conditions for pollen germination were sucrose 70 mg·L-1 ＋boric acid 5 mg·L-1＋28℃,the pollen germination reached 65.33%.
