| Summary: | Agr
opyron cristatum
(L.) Gaertn. (crested wheatgrass) is an endemic plant species, which
dominates most area of the Mongolian steppe and forest steppe. In the present study, spores of
arbuscular mycorrhizal fungi in the rhizosphere soil of crested wheatgrass
were isolated with wet-
sieving/decanting methods, and the major species was identifi ed as
Acaulospora scrobiculata
Trappe.
For arbuscular-mycorrhizal resynthesis, the spores of
A. scrobiculata
were propagated with corn
pot-culture technique and inoculated onto the roots of crested wheatgrass seedlings. The inoculated
crested wheatgrass seedlings exhibited vigor in growth, and examination of the root structure revealed
the occurrence of arbuscules and vesicles in the cortical cells. These results demonstrated that
A.
scrobiculata
could effectively form arbuscular mycorrhizas with crested wheatgrass and promote its
growth, which can be used to restore Mongolian grassland. |
