Different geographical and climatic features and various modes of growing and managing will also increase the difficulties of quality analyzing of seedlings. Therefore, the purpose of this study is to set up and improve the key analytic techniques in seedlings quality, and to forecast the efficiency of fine seedlings. We will investigate the root growth potential, Dickson Quality Index, the morphological and physiological attributes with non- destructive analysis technology, and then select the representative analytic indexes.苗木品質根生長勢Dickson品質指數健壯商數quality of seedlingsroot growth potentialDickson quality indexsturdiness quotient
