通过9个小麦品种的株高、旗叶长、旗叶宽、叶角、叶片刺密度、芒长、叶色和穗密度等形态特征与对抗禾谷缢管蚜关系的研究,发现在禾谷缢管蚜整个发生期小麦株高与抗蚜性呈极显著的负相关,叶片刺密度和穗密度与小麦抗蚜性呈显著正相关;蚜虫高峰期旗叶的宽度和长×宽与抗蚜性呈显著正相关;蚜虫始盛和高峰期的叶角与抗蚜性呈显著正相关;旗叶长、叶色和芒长与抗性无明显相关。
Based on the studies on the relationship between the morphological characteristics of 9 wheat cultivars, such as plant height, flag leaf length, flag leaf width, leaf angle, leaf spike density, mantle length, leaf color and spike density, There was a significant negative correlation between wheat plant height and resistance to aphids in the entire occurrence period of A. sojae. The leaf density and spike density were significantly and positively correlated with the resistance to aphids in wheat. The width and length × width of flag leaf at the peak of aphids were significantly correlated with resistance to aphids There was a significant positive correlation between the leaf angle and the aphid resistance at the beginning and the peak of aphids. There was no significant correlation between the flag leaf length, the leaf color and the mantle length and the resistance.
