Influence of rice allelopathy on sporocarp formation by Glomus monosporum in leaf sheath bases of wheat.

摘要

To analyse the effect of rice allelopathy on the sporulation of Glomus monosporum in wheat-rice cropping system, wheat stumps left after crop harvest and the rhizosphere soil were sampled 10 days after crop harvest from 5 sites in Pakistan. We found that when wheat is cultivated after rice crop and in soils having rice straw mulch, the ability of G. monosporum to form spores/sporocarps was decreased compared to monoculture in field and pot culture. The spore counts recorded in the soil samples after crop harvest also supported the leaf sheaths data.
