| Abstract: | The effects of nutrient solution on image characteristics of eucalypt seedling leaf images scanned from 3 clones were studied.Based on image processing technology,16 traits of leaf image involved color,shape and size features were analysed by principle component,and the PC complex indices were further established and used for statistic model.The results of regression model were showed: PC index could been significantly influenced by 3 factors including eucalypt clone and nutrient solution and leaf type,and ... |
