Abstracts |
Growth, root colonization pattern and spore density of arbuscular mycorrhizal (AM) fungi in the five tree species (i.e. Gymnacranthera farquhariana, Knema attenuata, Myristica dactyloides, M. fatua var. magnifica and M. malabarica) were studied. These tree species were planted in arboretum at Mangalore University, Mangalore, Karnataka, India. The soil in the study area was nutrient-deficient. The AM population developed after introduction of the plant species. Maximum height (48.95 inches) and diameter (24.73 cm) were recorded for M. malabarica, while the least growth was recorded for M. dactyloides (14.01 inches height with 4.76 cm diameter). Percentage colonization by the AMF in the planted species varied and maximum was in Gymnacranthera farquhariana (75.48) followed by M. fatua var. magnifica (72.1). The minimum colonization was observed in K. attenuata. The highest number of AM fungal spores (510 spores/100 g of soil) was observed in the rhizosphere of M. fatua var. magnifica, while the least (235 spores/100 g of soil) was recorded in K. attenuata. Species of Glomus such as Glomus fasciculatum, G. monosporum and G. macrocarpum were dominant in the region. |
