【摘要】 对10个梓树家系叶片数、单叶叶面积、单株叶面积方差分析表明,三者均达极显著性差异。叶片数、单叶叶面积、单株叶面积与树高、胸径均达极显著的线性回归关系,即单株叶面积愈大,生长愈快。更多还原

【Abstract】 The analysis of variance for leaf number, single leaf area and plant leaf-area of 10 families Catalpa ovata, the results showed that there were significantly difference among three factors. And leaf number, single leaf area, plant leaf-area and the height, breast height had reached extremely significant linear regression relationship. The plant leaf-area was bigger, the growth was faster.更多还原
