Abstract:
Field studies were conducted for a season to determine potential for alterations in the rhizosphere fungi quantity dynamics and dominant populations of 4 wild sugarcane clones(S.spontaneum L.) with different UV-B sensitivity under an enhanced ultraviolet-B(UV-B,280 nm～310 nm) radiation.The quantity of rhizosphere fungi was most in tillering stage,second in seedling stage and lest in elongating stage and maturing stage,the sequence wasn’t alternated by UV-B radiation.The rhizosphere fungi quantity of tolerant clone was obviously increased and greater than the sensitive clone under the enhanced UV-B radiation,however,the number of dominant populations decreased and Penicillium was the dominant population during the periods of 4 wild sugarcane clones.
