[Method] The powder was collected by the method of gravity glass slide, and the regulation of powders scattering of ＇Xinxin2＇ and ＂Wen185＇ which were the two main cultivated varieties of walnut in Xinjiang were studied. [Result] The results showed that the male inflo- rescence powder lasted for around 10 d, and centralized scatter powder was about 4 d, when walnut male at the daily mean temperature was from 20 to 24℃. Gen- erally, the large powder shedding amount was in east, south and central position of crown, in the range of 19 to 27 ℃, and the optimal temperature of powder scatter- ing was 20 to 23 ℃. [Conclusion] The pollens scattering regularities of walnut is closely related to temperature. With a favorable temperature, powder scattering per- forms outstandingly.展开更多
