Abstract

Abstract: Up to now,pot culture is the common method for producing AM fungi inoculum.Some factors can affect the quality of inooulum .In this paper, the effects of post-treatment,fungicide and planting density on the quality of inoculum of G.mosseae were studied. The result showed that the effect of post-treatment was abvious.In Sorghum vulgate Per,compared to the control, the post-treatment A and the post-treatment B increased spore number by 90.9% and 54.5%respectively.Spore development decreased 47.6% by fungicide Lide, while the other fungicides hacl no obvious influence on G.masseae growth .The experiment on planting density indicated that the spore number of 7 or 14 sorghums/9600 cm3 was greater than 21 or 30 sorghums/9600 cm³.

Key words: Arbuscular mycorrhizal fungi, G.masseae, Post-treatment, Fungicides, Planting density
