Effects of Storage Condition on Jatropha curcas Pollen Viability
The experiment was conducted with the pollens of 4-year-old Jatropha curcas L. to study the effects of different developmental stage and storage condition on pollen viability. The results showed that viability of fresh pollen was 100%, and pollen viability declined with the time prolonging. The difference of pollen viability was not significant in different developmental stages, however, it was significant under different storage conditions. Storaging pollen under -20 ℃ was the best tem-preture conditions followed by under 2 ℃ of cold storage. Pollen viability declined quickly under high temperature.
