平阴玫瑰花粉生活力及其贮藏条件的研究

Studies on Pollen Viability and Its Storage Conditions of Pingyin Rose

对22个平阴玫瑰品种的花粉进行了生活力测定及贮藏性能研究。结果表明,不同玫瑰品种以及在不同贮藏条件下的花粉生活力和耐贮藏能力不同。采收当日‘紫枝玫瑰’的花粉萌发率最高(90.0%),‘朱紫双辉’花粉萌发率最低(9.5%);花粉适宜贮藏条件为干燥、低温环境。花粉生活力随着贮藏时间的延长而下降,5月份室内自然温湿度条件下贮藏的花粉生活力下降较快,30d后绝大多数品种花粉活力降为零;冻藏(-4～-6℃)的花粉生活力下降较慢,60d后仍然保持较高的萌发率,一年后多数品种仍有一定的生活力。

The viability and storage capability of 22 pollens of Pingyin rose cultivars were studied. The results showed that the pollen viability and storage capability changed with the storage conditions and time in a different way with different cuhivars. The viability of pollen of ‘Zizhi Meigui’ （90. 0% ） on harvest day was the highest, while those of ‘Zhuzi Shuanghui’ （9.5 % ） was the lowest. The dry condition and lower temperature were better conditions for the rose pollens storage. Longer storage time and lower pollen viability. The pollen viabilities under natural conditions decreased very fast, and most of the cuhivars reached 0 after one month, while those of under the frozen conditions （ -4 - -6℃ ） decreased slower, and still maintained higher levels of viabilities after 60 days and a great numbers of pollens of cuhivars maintained viabilities after one year.
