为了解决锥栗杂交育种中的花期不遇问题,以‘华栗4号’花粉为试材,研究了在室温和4、-20、-80℃这4个贮藏温度条件下干燥处理和非干燥处理对锥栗花粉生活力的影响情况。结果表明：在不同贮藏温度条件下‘华栗4号’的花粉生活力和耐贮藏能力不同;花粉适宜的贮藏条件为非干燥、低温环境。花粉生活力随贮藏时间的延长而下降,室温干燥条件下贮藏的花粉其生活力下降最快,贮藏27 d后花粉活力基本丧失;4℃的温度条件较利于花粉的短期贮藏,贮藏30 d后其萌发率仍为32.6%;而-20和-80℃的温度条件均较利于花粉的长期贮藏,且-80℃下贮藏的效果最佳,-80℃下贮藏270 d后花粉仍有一定的生活力,而在-20℃下贮藏2...

In order to overcome the problem of flowering synchronism in Castanea henryi cross breeding, using ＇Huali No. 4＇ pollens as materials, effects of drying treatment and non-drying treatment on pollen viabilities were researched at room temperature, 4 ℃, - 20 ℃ , - 80 ℃ . The results showed that the viability and storage capability of ＇Huali No. 4＇ pollens were different under different storage conditions and temperatures, and non-drying condition and lower temperature were better conditions for pollen storage. Pollen vitality was gradually...
