本试验用含有EMS的石蜡油溶液处理10个玉米材料的成熟花粉，研究了EMS对花粉离体萌发率、M1代生理损伤以及M2代的诱变效应。
The mature pollens of 10 maize varieties (lines) were treated with EMS. The induction effects on the germinating rates, the physiological damage of M1 and M2 were studied.
在液滴培养盐胁迫条件下，棉花花粉粒萌发的百分率是反映其耐盐性的可靠指标，而花粉管的长度不能反映棉花的耐盐性。
The pollen germination percentages of the same 8 cultivars by sitting drop culture were also proved to be reliable indexes of salt tolerance, but pollen-tube growth were not.
