| 摘 要： | 试验以玉米自交系478为材料, 研究了不同温度, 培养基中不同蔗糖浓度, GA3 和硼酸等因子对玉米自交系花粉萌发的影响, 以及超声波处理后花粉萌发情况。结果表明: 24~27℃温度条件最适于玉米花粉萌发, 15%蔗糖时花粉的萌发率最高, 25~50mg/L硼酸和40mg/LGA3 对花粉的萌发有较好的促进作用。随着超声波处理强度的加大, 花粉的萌发率也在降低。

| Abstract: | Effects on the pollen germination of a maize inbred line,478 were studied. The pollen was treated at various temperatures, concentrations of sucrose, ultrasonic wave,GA 3 and boric acid,and plated on solid medium for germination.The results showed that the optimum temperature and sucrose concentration was 24~27℃ and 15% , respectively. The results also indicated that both 25~50 mg/L of boric acid and 40mg/L of GA 3 enhanced the germination. With the increment of ultrasonication intensity, the germination rate of the pollen gradually decreased. |
