To study the effects of AMF( arbuscular mycorrhizal fungi) inoculums on seedling growth of cucumber,vegetable seeds were inoculated with two kinds of AMF inoculums BF( mycorrhiza for plants) and VT( mycorrhiza for vegetables) from Czech Republic during sowing in trays in greenhouse. The root AMF infection rates in seedlings were 49. 30% and 37. 65% respectively after 35 d growth. The plant height,stem diameter,fresh and dry weight of those seedlings inoculated with BF and VT were higher than that in CK. Compared with the CK,VT inoculation significantly improved the root activity,chlorophyll content and photosynthetic rate of cucumber seedlings. Comprehensive analysis showed that VT could promote seedling growth of protected cucumber.
