| Abstract: | Based on observation records of growth traits of 40 Catalpa fargesii clone seedling collected from Gansu province territory,different significant analysis and grey relational analysis of traits indicators,optimal clones were se-lected from aspects of morphology growth and physiological photosynthesis.The results showed that among 40 Catalpa fargesii of the experiment,5 clones including 'Tiangu hui 04','Tian hui 34','Zhenqiu 04','Maijishan hui 3','Zhuangkuo hui 5' had significant difference(P<0.05) with othe... |
