通过对 9 个品种小麦麦株内可溶性糖含量分析及其对禾谷缢管蚜生长发育影响的研究,初步明确了在一定范围内,小麦麦株内可溶性糖含量与蚜虫内禀增长率呈极显著正相关,与若蚜历期呈负相关。蚜虫的排蜜露量与小麦维管束膨压呈正相关,蜜露中含糖量则与食料中含糖量呈显著正相关。初步认为小麦品种对禾谷缢管蚜的抗性与麦株内可溶性糖含量呈负相关。
Based on the analysis of soluble sugar content in nine varieties of wheat and its effect on the growth and development of Aphis gossypii, it was initially clarified that within a certain range, the content of soluble sugar and the intrinsic rate of increase of aphids in wheat Significant positive correlation, and negative correlation with the duration of the nauplius. There was a positive correlation between aphids’ nectar exponent and wheat vascular bundle turgor pressure. The content of sugar in nectar was positively correlated with the content of sugar in foodstuff. The results showed that there was a negative correlation between the resistance of wheat cultivars to Aphis gossypii and soluble sugar content in wheat plants.
