摘  要：
旨在研究内生真菌对油樟挥发油积累及生理生化特性的影响。以4株内生真菌(2J1、3J1、5J2、YB)作为材料,将内生真菌孢子悬浮液均匀喷洒在油樟叶片上进行处理后,提取油樟叶片中的挥发油,利用GC-MS测定挥发油中1,8-桉叶油素、α-松油醇的量。结果显示,采用2J1和3J1两种内生真菌对油樟进行处理,在处理21 d时挥发油含量达到最大值,其主要成分1,8-桉叶油素分别比对照高出201.53%、174.47%,α-松油醇高出364.14%、307.29%,且过氧化物酶(POD)、过氧化氢酶(CAT)活性及丙二醛(MOD)的含量有显著提高;由5J2和YB处理的油樟挥发油含量、POD与CAT活性以及MOD含量与对照相比差异均不显著。采用2J1和3J1处理油樟植株,能有效提高油樟挥发油的含量。

摘  要：
The aim of this study was to examine the effects of endophytic fungi on the accumulation and physiological-biochemicalcharacteristics of essential oil in Cinnamomum longepaniculatum. The essential oil of C. longepaniculatum was extracted after spraying fourendophytic fungi spore suspension(2J1、3J1、5J2、YB)on the leaves separately,and the content of 1,8-cineole and α-terpineol wasdetermined by GC-MS. The results showed that the content of essential oil reached a peak at 21 d after treatment with 2J1 and 3J1,and thecontents of 1,8-cineole increased by 201.53% and 174.47% compared with controls,and α-terpineol increased by 364.14% and 307.29%as well,respectively. Furthermore,the peroxidase(POD)content,catalase(CAT)activity,and malondialdehyde(MOD)content ofsuspension cells increased significantly. No significant difference was detected between C. longepaniculatum treated with 5J2 and the controlgroup in terms of essential oil accumulation,CAT and POD activity,and MOD contents,nor did YB. Consequently,treatment with 2J1 and3J1 could significantly increase the accumulation of essential oil in C. longepaniculatum.
