摘要: The growth difference between seedlings gradually manifested after they were transplanted to nursery. If environmental conditions were the same, then such differences resulted from individuals. The seedling morphology usually was the first standard and convenient to judge if the seedlings could be planted in the field. But whether the quality of seedlings could look from morphology? This study divided 230 seedlings of Michelia compressa into three levels, and then planted in the nursery. After 6 months later, to measured the morphological and physiological characters of seedlings, including height, basal diameter, numbers of node, internode length, dry biomass, chlorophyll index, photosynthesis and leaf fluorescence reaction. This experiment tried to figure out the relationship between morphology and physiology of seedling from the above results. The morphological parameters (height, basal diameter, numbers of node, internode length, Dickson quality index) showed significant difference among the three seedling levels. In terms of biomass, although the first seedling level had higher height, but not resulted in excessive growth. There was no significant difference between the first and second level seedlings in chlorophyll index, stomatal conductance, photosynthesis and Fv/Fm, but higher than the third seedlings. The difference between the first and second level seedlings unable to get from those physiological parameters, indicating the quality of seedlings could not only look from morphological characters.
