贮藏温度和湿度对胡萝卜花粉生活力的影响

The influence of storage temperature and humidity on carrot pollen viability

采用液体培养基萌发法测定贮藏于室温、冷藏和冷冻条件下干燥与否的胡萝卜花粉生活力。结果表明:胡萝卜花粉的生活力在相同贮藏条件下随时间的延长逐渐降低,贮藏温度越低,生活力下降速度越慢;干燥贮藏花粉生活力高于非干燥贮藏花粉。本试验条件下,冰箱冷冻干燥贮藏最有利于保持胡萝卜花粉的生活力。

The effects of storage temperature and humidity on carrot pollen viability were studied by germinating tests in liquid medium.The results showed that the pollen viability gradually decreased with the storage time lasting,and the lower the storage temperature,the slower the viability descending rate;The pollen viability was higher in dry storage than in non-dry storage,and freeze-drying storage was the best in keeping the pollen viability.
