| Abstract: | Growth process and rules of clonal triploid of Populus tomentosa during Seedling Stage were studied in this paper.Using methodology of grey correlation analysis,relationship between growth in height during seedling stage and climatic factors were analyzed.Results showed that growth of clonal triploid of Populus tomentosa had significant stage.Growth process appeared the rule of slow fast slow and existed obvious fast growing period. |
