Abstract:
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 2011 and 2012 were 8% and 36% respectively，while that of the ray flower in 2011 and 2012 were 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.
