Abstract:
Three cultivars were used as materials,their were ‘Changfu 2’,‘Fuhongzaoga’,‘Yanfu 6’.All trees were trained to a slender spindle configuration.The fractal dimension of 2-D images with and without leaves employing a box-counting dimension number combined with Photoshop image processing technology were investigated.The influence of leaves weight and shoots length on fractal dimension number were analyzed by investigated the relationship among three kind of shoots length (trunk,main shoots,lateral shoots),leaves weight,and linear regression of 2-D fractal dimension number.The results showed that the fractal dimension,the shoot length and leaf weight were significantly different among the three cultivars;The contribution rate of leaves (CRL) to tree architecture varied between 14.72% to 16.70% for the three cultivars;As the shoot length and leaf weight increased,the fractal dimension and CRL significantly increased.The fractal dimension can be used as an index to evaluate the architecture of apple trees,and guidelines to direct train,thin activities.
