为探索松树蜂入侵后的樟子松内栖真菌与健康状态樟子松内栖真菌的组成差异,本文对松树蜂入侵后不同健康状态(健康、衰弱、死亡)樟子松的不同主干高度(基、中、上)内栖真菌进行研究。共分离到樟子松内栖真菌25属37种,其中健康木分离到13种,多为腐生菌和内生菌;衰弱木分离到23种,多为致病菌和腐生菌;死亡木分离到11种,多为腐生菌。不同主干高度而言,健康木中部真菌检出率最大,为55.2%,基部真菌种类最多,为9种;衰弱木上部真菌检出率最大,为100.8%,基部真菌种类最多,为13种;死亡木上部真菌检出率最大,为106.4%,上部真菌种类最多,为8种。不同健康状态内栖真菌的数量为:死亡木>衰弱木>健康木;内栖真菌种类为:衰弱木>健康木>死亡木。结果为研究樟子松不同健康状态下的优势内栖真菌与松树蜂及共生菌的关系奠定了基础。
In order to explore the differences in the composition of endophytic fungi between C. medinalis and Pinus sylvestris var. Mongolica after pine tree bee invasion, the effects of different trunk height (healthy, weak, dead) of Pinus sylvestris var. Basal, medium, upper) inhabiting fungi. A total of 37 species were found in 25 genera of Pinus sylvestris var. Mongolica, of which 13 species were isolated from healthy wood, most of which were saprophytic and endophytic; 23 species of weak wood were isolated, mostly pathogenic and saprophytic; To 11 species, mostly saprophytic bacteria. In terms of height of trunk, the detection rate of fungi in the middle part of healthy wood was the highest (55.2%), the number of fungi in the base was the largest (9), the fungi in the upper part of the diseased wood was the highest (100.8%) and the fungi The highest rate of dead wood in the upper part of the dead wood was 106.4%, and the highest number of the upper fungi was 8 species. The number of endophytic fungi in different states of health was: dead wood> frail wood> healthy wood; the species of endangered fungi were: frail wood> healthy wood> dead wood. The results laid the foundation for the study of the relationship between dominant species of endangered fungi and pine needles and symbionts in different states of Pinus sylvestris var. Mongolica.
