Lack of reliable methods to propagate pure cultures of VAM in vitro remains a constraint to production and quality control of VAM inocula for large-scale agronomic use.
缺乏可靠的VAM体外培养方法仍是限制供农业上大范围的VAM接种剂生产和质量控制的因素。
The result shows that there are obvious difference in the colonization rate, density and species number of AMF when the inocula are soil from the different plant community.
