摘要/Abstract

摘要： 通过气相色谱分析研究了高抗、中抗和敏感马尾松种源在接种松材线虫 (PWN)后所引起的中性萜类 (主要是倍半萜类)组分含量变化规律以及含量变化与种源抗性间相关性变化规律。结果表明,接种PWN使抗性马尾松种源中某些萜类组分如长叶烯等增多,而某些组分如反式石竹烯等减少 ;接种PWN使高抗种源中长叶烯与反式石竹烯含量比值先减小后增大,且超过接种前的水平,但是未改变种源的抗病特征 ;树木生长过程对种源抗性及本研究没有造成影响和干扰。

Abstract: The variation relationships of neutral terpenoids (mainly sesquiterpenoids) were investigated through GC determination of the different resistant provenances (high resistance: H, middle resistance: M and low resistance: L) of Pinus massoniana after they were inoculated with Bursaphelenchus xylophilus (pinewood nematodes, PWN). The results showed that the inoculation led to increase of some components such as longifolene with the inoculated days in the H and M provenances, but led to decrease of some compounds such as trans-caryophyllene in all three provenances. The inoculation of PWN into the H provenance resulted in the decrease followed by the increase of the ratio of contents of longifolene and trans caryophyllene. However,the inoculation did not finally change the resistance of masson pine provenance, and the growth did not affect the resistance, too.

Key words: neutral terpenoids, pinewood nematode (PWN), resistance mechanism, resistant provenance of masson pine, pine wilt
