Mycorrhizal Dependency of Ten Seedling Species for Landscaping and the Inoculation Effects
10种绿化苗木对VA菌根的依赖性及其接种效应

Infection rate,mycorrhizal dependency and inoculation effect were determined in 10 seedling species for landscaping infected with VA(Glomus moseae Gerdemenn et Trappe). The tested species were Ficus elastica cvs. Variegaa,Decora,Decora Burgundy,Decora Tricolor,Carallia brachiata,Dracaena deremensis,Artocarpus nitidus subsp. lingnanensis,Anneslea fragrans,Eurycorymbus cavaleriei,and Photinia serrulata. The infection rate was in the order: Decora burgundy>Variegaa>C. brachiata>DecoraTricolor>Decora>D. deremensis and A. nitidus subsp. lingnanensis>A. fragrans > E. cavaleriei > P. serrulata. Decora Burgundy and Variegaa showed highest mycorrhizal dependency of over 300%,followed by Decora and Decora Tricolor of 213.3% and 203.5%,respectively,whereas the other 6 species had lower dependency of less then 200%. The inoculation effect was highest in Decora Burgundy,Decora Tricolor,Decora,Variegaa and C. brachiata,and higher in D. deremensis,A. nitidus subsp. lingnanensis. The lowest inoculation effect was found in P. serrulata,A. fragrans and E. cavaleriei.
