- Abstract:
- Pollen vitality of 5 walnut cultivars ‘Xiangling’，‘Xilin 3’，‘Xiluo 2’，‘Chandler’ and ‘Hartley’ were determined by TTC staining and in vitro culture method under different storage temperatures and time．The results showed that，the pollen viability of 5 walnut cultivars were the lowest at room temperature (20℃) while higher at 3℃ and -20℃；with the extension of storage time，the pollen viability decreased significantly and TTC staining was significantly higher than in vitro culture method.Two methods for determining had a significant correlation.The suitable condition was at 3℃ for ‘Xiangling’，‘Xilin 3’，‘Xiluo 2’，‘Chandler’ pollen storage and at -20℃ for ‘Hartley’，the storage time was 6-9 days.
