松材线虫病是松树的一种毁灭性病害.本文对接种松材线虫后3~4年生黑松茎部的一些生理生化指标的变化进行了研究.结果显示,接种线虫后,松苗的可溶性糖含量降低,在病情发展中期和后期比早期降低更显著.松苗的可溶性蛋白质和抗坏血酸含量逐渐降低,游离氨基酸含量也降低.松树茎部的可溶性蛋白质含量可用于病害的早期诊断.此外,对这4个生理生化指标在病害致病机理中的作用进行了讨论.
鬆材線蟲病是鬆樹的一種燬滅性病害.本文對接種鬆材線蟲後3~4年生黑鬆莖部的一些生理生化指標的變化進行瞭研究.結果顯示,接種線蟲後,鬆苗的可溶性糖含量降低,在病情髮展中期和後期比早期降低更顯著.鬆苗的可溶性蛋白質和抗壞血痠含量逐漸降低,遊離氨基痠含量也降低.鬆樹莖部的可溶性蛋白質含量可用于病害的早期診斷.此外,對這4箇生理生化指標在病害緻病機理中的作用進行瞭討論.

Pine wilt caused by pine wood nematode, Bursaphelenchus xylophilus, is a serious disease for pines. In this paper, changes of some physio-biochemical indexes in stem of 3-4 years old Japanese black pine, Pinus thunbergii inoculated with B. xylophilus were studied. The results showed that after nematode invasion, the soluble carbohydrate in pine seedlings decreased, and it was more significant at the middle and late stages of disease development. The soluble protein and ascorbic acid in pine seedlings decreased gradually, and the free amino acid in pine seedlings also decreased. It was suggested that the content of soluble protein in stems of pine could be used for early diagnosis of the disease. Roles of the four physio-biochemical indexes in pathogenic mechanism of the disease were discussed.
