摘　　要：以2个杂交谷子新品种为材料,连续两年在田间自然播种条件下进行杂交谷子叶龄指数与穗分化时期回归关系的试验研究。结果表明,各品种的叶龄指数与穗分化时期之间均呈极显著的正相关关系,回归方程的检验达极显著水平。可利用回归方程,依据叶龄指数的观测值来预测穗分化时期。Taking two Hybrid foxtail millet varieties as test materials, the regression relationship between the leaf number index and spike differentiation were studied under the farm. The results showed that it got significant level at 0.01 between the leaf number index and spike differentiation stages for each variety by regression analysis. With regression equation, the foxtail millet spike differentiation stages could be forecasted according to leaf number indexes.
