| 摘 要： | 通过接种马尾松毛虫Dendrolimus punctatus和人工剪叶，分析比较了不同受害方式对马尾松针叶内化学物质的影响。结果表明，害虫取食松针诱导的次生代谢物质(单宁、酚类物质)比人工剪叶处理略有增加，而营养物质-可溶性糖变化不大。对马尾松进行害虫取食为害、人工剪叶受害、未受害三种处理后，连续3年跟踪测定了松针叶内化学物质含量的变化。结果发现，无论是害虫取食为害，还是人工剪叶受害，针叶内次生代谢物质含量都减少，可溶性糖含量降低，直至一年后才恢复到原有的水平；蛋白质变化的趋势则始终是受害处理的含量比未受害处理的含量高，表明马尾松受害后诱导的化学物质变化具有滞后特性。

| Abstract: | Effects of infestation of the pine caterpillar, Dendrolimus puncatus and needle\|cutting on the chemical components in the needles of Pinus massoniana were investigated for 10 days after treatment.Higher tannin content and lower contents of phenols and soluble sugars were found in the needles of the pine infested by the caterpillar than injured by needle\|cutting,but the differences did not reach the significant level,indicating no obvious differences of these components during that term in response to the two injurious manners. The changes of nutritional material (soluble sugars) and secondary metabolites (tannin and phenols) in the needles of P.massoniana injured by infestation of the pine caterpillar or needle\|cutting and in the needles of control pine were monitored for three successive years.It showed that contents of the secondary metabolites in the needles of the pine damaged by the two manners fluctuated along with time.They decreased in the first year after treatment and then went up to the normal level.Protein content in the needles of treatment pines was always higher than that in the control.Therefore,the induced chemical changes in the needles usually lag behind. |
