By the means of germination in vitro,the effects of different culture media,preservation condition and drying time on the germination of pollens in Chimon anthus praecox‘Luteus' were studied.The results showed that the pollen dried for 4hours and then incubated 4hours on the medium,which is composed of 10%sucrose+75mg·L~(-1) H_3BO_3+0.1‰ CaCl2+50mg·L~(-1) GA_3,reached the highest germination rate.Storing for two days,the vitality of pollen dried for 4hours shows extinct descent.The germination rate of pollen stored at-20 ℃for 6days was higher than that of at 4 ℃ and 20 ℃,respectively.The vitality of the pollen stored for 8days is less than 1%.The results can provide a reference for the measurement and analysis of pollen viability,the orientation of pollen preservation in future is also suggested.
