| 摘 要： | 本研究以采自甘肃夏河桑科草原和甘加草原的野生中华羊茅(Festuca sinensis)为材料,通过对种子和茎髓部内生真菌带菌的检测,并在PDA培养基上进行分离培养,总共得到48个内生真菌菌株.再经水琼脂培养基次级培养以促进产孢,依据菌落生长形态、分生孢子、分生孢子梗等形态学特征的现察与测定,最终可将其分为3个形态群....

| Abstract: | All of the Chinese fescue(Festuca sinensis) samples tested in the study were collected from Sangke and Ganjia grassland of Gansu Province.A total of 48 endophytic fungal strains were isolated and purified from Chinese fescue seeds and plants.Based on the observation and measurement of the morphological characteristics of the appearance of colony,conidia and conidiophores,all isolated examples were classified into 3 types.13 of 48 strains were belonging to the ZHYM-Ⅰ morphological group,20 were ZHYM-Ⅱ,15 were ZHYM-Ⅲ.A significant diversity was observed among the 48 strains in morphology. |
