The effects of fire on Arbuscular Mycorrhizal colonization in forage plants

摘要

The influence of fire on arbuscular mycorrhizae (AM) colonization was studied in two field trials in 2005. The plants were native grasses Phragmites communis and Aneurolepidium sp. in a Hexi corridor trial; Aneurolepidium sp., and the cultured grasses Festuca arundinacea . Poa prapensis, and Bromus inermis in a Xifeng trial. Burning increased AM colonization of Aneurolepidium sp. significantly in both trials (P < 0.05). The AM colonization of burning treatments in the Hexi Corridor were 37. 4% and 21. 7%, but were only 31. 2 % and 16. 6% at Xifeng. Burning decreased AM colonization of the remaining grasses, significantly (P < 0.05) of B. inermis, the colonization rates were 29. 8% to un-burnt grass and 24. 9% to burnt.
