Abstract:
vUsing the fractal theory and imaging technology,the different cultivars and viewpoints were indicated,first proposed the new conception of the Contribution Rate of Leaves(CRL),which was used as a parameter for leaves spatial distribution within the tree architecture.The results showed that,by comparing the fractal dimensions of Y shaped apple trees among five cultivars,the results revealed that the fractal dimension had the positive correlation with the length and quantity of shoots；there was significant difference of fractal dimensions in different apple cultivars；the comprehensive evaluation showed that ‘Nagafu 2’>‘Yuhuazaofu’>‘Fuhongzaoga’>‘Yanfu 6’>‘Li Gala’；comparing the fractal dimension front view and side view images showed that the fractal dimensions of side view images were larger than front view ones；the fractal dimension varied from 1.592 to 1.661 and the CRL varied between 15.13% and 19.6% for the five cultivars.For the side view images,the fractal dimensions varied from 1.627 to 1.728 and the CRL varied between 1655% and 18.87%.CRL could be characterized as space distribution state in the tree structure.
