选用东农７０４番茄品种，分别在不同叶龄期进行低温处理，处理的温度是１５℃／５℃（昼／夜），时间３天，在开花期利用石蜡切片技术和四唑染色法观察花粉的育性和生活力，结果表明：番茄在７、８片叶龄期进行低温处理对花粉的育性和生活力影响最大，败育主要发生在小孢子形成阶段，低温条件下花粉生活力与座果率呈正向显著相关。
The Dongnong 704 tomato varieties were selected to conduct low temperature treatment at different leaf ages, the treatment temperature was 15 ℃ / 5 ℃ (day / night), the time was 3 days. The pollen was observed by the method of paraffin section and tetrazolium Fertility and viability of tomato. The results showed that tomato had the greatest effect on the fertility and viability of pollen at the 7th and 8th leaves. Abortion mainly occurred during microspore formation. Pollen viability at low temperature Fruit rate was positively correlated significantly.
