摘  要:
以"斗南"苹果为试材,研究比较了疏花蔬果时保留中心花和保留边花对其所结果实霉心病发病率、单果重及果形指数的影响。结果表明:2011年和2012年中心花所结果实霉心病发病率分别为8%和36%,边花所结果实霉心病的发病率分别为4%和17%;边花所结果实与中心花所结果实的单果重、果形指数无显著差异。可见,疏花时选留边花坐果可以降低"斗南"苹果霉心病的发病率。

摘  要:
Taking apple cultivar‘Dounan'as material,the influence of flower thinning central flower or ray flower on apple moldy core disease incidence,single fruit weight and fruit shape index were studied and compared.The results showed that the disease incidences of apple moldy core of the fruits setting from central flower in 2011and 2012were 8% and 36%respectively,while that of the ray flower in 2011and 2012were 4% and 17%.There were no significant differences between the single fruit weights and fruit shape indexes of the two groups.In conclusion,the disease incidence of apple moldy core could be reduced by keeping ray flower during flower thinning.
