摘要
试验结果表明，甜荞第１ ～１０ 层真叶叶龄模式的回归方程为 Ｙ ＝ ４ ．３３ ＋ ３ ．１４ Ｘ 。叶片长、宽和面积从下至上逐叶增大，第４ 叶最大，往上逐渐减小，顶部叶片最小。叶形指数的变化趋势与叶片大小的变化趋势相反，以顶部叶片最大，第３ 叶最小。３
Experimental results indicated that the regression equation of the model of leaf age from first to tenth layers is Y = 4.33+3.14 X . The length, width, and area of the leaves increased leaf by leaf upward till the fourth one and then decreased till the top. The change trend of leaf shape index is just the opposite to the trend of leaf area. The top leaf is maximum and the third one minimum. Three leaves stage is the conversion period.
