Abstract:
In order to clear the best pollination time，taking‘Hayward’,‘Xuxiang’,‘Yate’as test material，using handpollinate method,the effect of pollination at different time on the characters of kiwifrut was studied.The results showed that the single fruit weight of delicious kiwifruit were 104.6 g and 102.1 g at 07：00—11：00 and 15：00—17：00 on a sunny day，respectively.The single fruit weight were 89.1 g and 94.6 g at 13:00 and 19:00 respectively which was low.The average weight of 91.9 g was lower 11.5 g than the average weight of 103.4 g in the morning and afternoon，a decrease of 11.1%.When ‘Xuxiang’ and ‘Yate’ were pollinated at 6：00，9 ℃,its single fruit weight was lower 28.3 g than the two times that pollinated in the morning and afternoon whose single fruit weight was 100 g，and its fruit setting rate was lower 29.9 than the day fruit setting rate.When ‘Xuxiang’ and ‘Yate’ were pollinated at 13：00 whose humidity was 29%,its single fruit weight was lower 8.9 g than the two times that pollinated in the morning and afternoon，and its fruit setting rate was lower 11.7 percentage point than the day fruit setting rate.Look from different species，fruit weight daily variation of ‘Hayward’ was similar to‘Xuxiang’,while ‘Yate’ was the opposite.In the production，we should mainly pollinate in the morning on a sunny day，couldn ’t pollinate when the temperature below 9 ℃.It was inappropriate at 13：00—19：00 to pollinate.
