Abstract:
To investigate variation of phenology and growth of thirty-three Cerasus cultivars with red flowers in Hangzhou,the characteristics of phenology and growth,and the relationship between these characteristics and environmental were analyzed based on survival percentage of grafting,annual growth and phenological period,which would be helpful for planting and managing.The results showed that the survival rate of grafting of twenty-six cultivars in all cultivars was more than 85%.Twenty-two cultivars were high disease resistant,including Cerasus serrulata ‘Asahiyama’,C.serrulata ‘Hanagasa’, C.×kanzakura ‘Kawazu-zakura’ et al.In phenology,these cultivars had abundant variation,especially the date of leaf bud germination,with the coefficient variation of 11.69%.The maximum range of leaf fall was 96 days,and the coefficient variation of stay green was 11.10%.Both intra- and inter- of phenology traits and growth traits were relevant.The growth traits were negatively correlated with leaf bud germination date and leaf expanding date,and were positively correlated with leaf discoloration date and leaf fall date.Using principle component analysis (PC),the phenology traits and growth traits were synthesized into three components.According to the values of PC,all of the cultivars were divided into four types,short growth-period type,long growth-period type,early phenology type and middle type.
