渭北富士苹果偏斜果的影响因素
Study on the fruit shape of Fuji apple in Weibei area
摘要
Abstract
With the purpose of resolving the lopsided fruits of Fuji apple , the experiment was conducted on 16~17 year old Fuji apple trees (Malus domestica Borkh , cv Fuji) , and mainly studied the effects of the pollination and fertilization , the type of fruits on the fruit shape of Fuji apple at the Baishui Apple Station of Northwest A & F University in 2009 ~2010 . The results showed that in addition to Pink Lady , the Qinguan , Gala and Starkrimson pollination could reduce the unsymmetrical index and improve the fruit shape . The number of stigmas had significant effect on the fruit shape of Fuji apple , removed 3~4 stigmas could obviously reduce the seeds and lead to develop into the deformed fruit . The seed numbers and the seed distribution in the ventvicles of determined the fruit shape , almost every ventricle had seed distri- bution in the symmetrical fruit, but at least one ventricle of seed was abortion in the unsymmetrical fruit and two ventri- cles of the seed were abortion in the deformed fruit . In three fruit branches , the fruit shape index of the long fruit branch was significantly greater than the medium fruit branch and the short fruit branch , the fruit unsymmetrical index was smaller than the other fruit branches, but the difference was not significant. In the different fruit ways , the drooping fruits were symmetrical and less deformed fruits , and the obvious difference in the fruit shape arcsine with the lateral fruit .关键词
