用透射电子显微镜观察了春、夏、秋、冬四个季节的沙棘根瘤,以及瘤瓣上、中、下三个部位。结果表明,不同季节,不同部位的瘤瓣内,根瘤内生菌有7种不同形态。即侵染菌丝体、繁殖菌丝体、营养菌丝体、春孢子及春孢子囊、泡囊,冬孢子及冬孢子囊和类菌体。在多年生珊瑚状的根瘤中,它们的世代交替是:春夏季以侵染菌丝、繁殖菌丝、营养菌丝、春孢子囊及春孢子、泡囊为主;秋冬季以衰退的营养菌丝、衰老泡囊、冬孢子囊和冬孢子、类菌体为主。冬孢子和类菌体是休眠体。
Transmission electron microscopy was used to observe the root nodules of seabuckthorn in spring, summer, autumn and winter as well as the upper, middle and lower parts of the tumor flap. The results showed that in different seasons, different parts of the tumor flap, root nodulation endophytes have seven different forms. Ie infecting mycelium, propagating mycelium, vegetative mycelia, spring spores and spring spores, vesicles, teliospores and teliosporangia and mycobacteria. In perennial coral-like nodules, their generation alternation is: in spring and summer to infect mycelium, mycelial growth, vegetative mycelium, spring spores and spring spores, vesicles; melon mycelium, Aging vesicles, teliospores and teliospores, the main type of bacteria. Winter spores and fungi are dormant.
