研究了作物在秋季生长停止期间,根据其形态生理指标预测产量稳定程度的方法.这个方法建议选择同标准品种比较其叶片中叶绿素含量、单位面积上作物地上部分的重量及株数,变化率平均值最低的品种.多年的试验表明,用形态指标的变化程度比用小区谷物实际产量的变化评定品种产量的稳定性更为准确. This paper studied the method of predicting yield stability according to the morphological and physiological indexes of crops during the period of their ending growth in autumn.This method suggested to compare the chlorophyll content of the leaves with the standard varieties, the weight and number of the aboveground parts of the crop, the average rate of change The lowest variety.Experiments have shown that the stability of the yield of the varieties is more accurately assessed by the degree of change of the morphological indexes than the actual output of the cereal community.
