摘　　要：通过花粉培养、显微镜观察的方法，研究了不同温度、营养、保藏条件对花粉生活力的影响，结果表明，西瓜花粉萌发适宜温度为18～38℃，上限温度为48℃，下限温度8℃，在较高生长温度条件下形成的花粉生活力较强；低温处理时间越长，对花粉发芽越不利；8℃低温、干燥条件有利花粉短期保存；营养充足的大型花蕾花粉萌发较好。Effects of the temperature, nutrition and storage on the vigor power of the watermelon pollen were studied through the pollen cultivation and microscope observation. The results were showed as follows： the germinating temperature of the watermelon pollen is 8 - 48 ℃, 8 ℃ and dry environment was advantage to pollen storage for short times. The lower temperature and longer time of treatment was disadvantage to the germination of pollen. The germination of the big and nourishing bud is better. The study provides a reference for the productive practice and scientific research.
