| 摘 要： | 通过对松突圆蚧不同抗性程度的马尾松未受害针叶和受害针叶的针叶长度、叶鞘长、叶鞘松紧度、含水率、相对含水率和容重的测定，研究发现：马尾松针叶长度与其对松突圆蚧的抗性成反比，马尾松针叶的容重与其对松突圆蚧的抗性成正比，叶鞘长、叶鞘松紧度与抗虫性不相关。

| Abstract: | By comparison of the length about needles and leaf sheath, leaf sheath tightness, water content, relative water content and bulk density in undamaged and damaged needles, the resistant masson pine needle length and pest resistance is inversely proportional to the bulk density, and the pest of pine needles is proportional to the sheath length, leaf sheath, not related to the tightness and resistance to insects. |
