竹缺爪螨危害对毛竹生理生化影响的初步研究

Preliminary Studies on the Influence of the Aponychus corpuzae Harm on the Physiology and Biochemistry of Phyllostachys pubescens

本文报道毛竹上重要害螨一竹缺爪螨ＡｐｏｎｙｃｈｕｓｃｏｒｐｕｚａｅＲｉｍａｎｄａ）危害对毛竹生理生化影响。研究表明：毛竹叶片受害程度与叶绿素含量，还原糖含量，总糖含量，含水量呈明显负相关关系。其数学模型分别为：Ｙ叶绿素＝１．５－０．２１８５Ｘ（Ｒ＝－０．９７）；Ｙ总糖＝４．５８６－０．８１Ｘ（Ｒ＝－０．９８）；Ｙ还原糖＝３．１４３－０．３８６８Ｘ（Ｒ＝－０．９４）；Ｙ含水量＝３０．４９－５．１５Ｘ（Ｒ＝－０．９０）。并对综合治理提出对策。

The studies demonstrate that the harmed degree of Phyllostachys pubescens blades assumes the evident negative correlation with the chlorophyll,reducing sugar,total sugar and moisture content.Their mathematical models are as follows:Ychlorophyll=1 5-0 2185X(R=-0 97);Ytotal sugar=4 586-0 81X(R=-0 98);Yreducing sugar=3 143-0 3868X(R=-0 94);Ymoisture content=30 49-5 15X(R=-0 90).This paper also puts forward some countermeasures for the comprehensive harnessing.
