Abstracts |
The occurrence of arbuscular mycorrhizal (AM) fungi was investigated in six varieties of Carica papaya L in tropical agrobased ecosystem of Goa, India. All the varieties selected for the survey (CO-1, Coorg honeydew, CO-2, Sunrise solo, Washington and Local) were colonized with AM fungi. The root colonization ranged from 26 to 77%, while the spore density ranged from 100 to 236 spores per 100 g of rhizosphere soil. Total nitrogen, available potassium and organic carbon content of the rhizosphere soil along with root colonization and spore density of AM fungi varied significantly in different varieties of papaya. Available phosphorus and available potassium recorded significant negative correlation with spore density of AM fungi. However organic carbon, available phosphorus and total nitrogen recorded significant positive correlation with root colonization of AM fungi. Thirteen species of AM fungi belonging to the genera Acaulospora, Glomus, Gigaspora and Destiscutata were found to be associated with the varieties of papaya considered. |
