根据2010年7月—2011年6月采自河北省安国市金银花根围0～30 cm土壤样品数据,运用典型相关分析,研究了金银花根围AM真菌、球囊霉素、土壤环境三者之间的相关关系。结果表明:AM真菌与土壤环境之间的典型相关性以土层因素与泡囊定殖率之间最密切(r=0.89),球囊霉素与土壤环境之间的典型相关主要表现在总球囊霉素与有机碳之间(r=0.87),AM真菌与球囊霉素之间的典型相关主要表现在总球囊霉素与孢子密度之间(r=0.85);土层与泡囊定殖率、孢子密度和总球囊霉素呈显著负相关;土壤全氮与外生菌丝定殖率呈显著正相关,但与丛枝菌丝定殖率呈显著负相关;另外,球囊霉素与孢子密度和菌丝定殖率呈显著正相关;其中总球囊霉素与泡囊定殖率呈显著正相关,表明球囊霉素可能储存于泡囊中。
According to the data of 0 ~ 30 cm soil samples collected from the root of Honeysuckle in Anguo City, Hebei Province from July 2010 to June 2011, Canonical correlation analysis was used to study the relationship between AM fungi, glomycin and soil environment The correlation between. The results showed that the typical correlation between AM fungi and soil environment was the closest between soil layers and vesicle colonization rate (r = 0.89). The typical correlation between the concentration of gentamycins and soil environment was mainly as follows: total The typical correlation between AM fungi and glomomycin was mainly between the total glomerulus and spore density (r = 0.85), between the gentamycins and organic carbon (r = 0.87) There was a significant negative correlation between colonization rate, spore density and total gemcitabine. Soil total nitrogen was positively correlated with the colonization rate of ectomycorrhizal fungi, but negatively correlated with the colonization rate of arbuscular mycorrhizas. In addition, Globulin was significantly and positively correlated with spore density and mycelial colonization rate. There was a significant positive correlation between total gemcitabine and vesicle colonization rate, indicating that the gemcitabine may be stored in vesicles.
