Agalawatte, 1984) Jayaratne, A.H.R.; Peries, O.S.; Waidyanatha, U.P. De S.Hevea seedlings showed a slight growth responce when inculated with Gigaspora margarita out of four species, tested in sterilised soil. There were no significant differences in the uptake of nutrient by mycorrhizal Hevea plants. Non-mycorrhizal Pueraria plants grew very poorly unless they were given liberal quantities of phosphate fertilizer, confirming previous reparts. All mycorrhizal plants took up more nutrients from soil than non-mycorrhizal plants. Effective nodule formation wassignificantly grater in mycorrhizal plants when phosphorus was added.Item Endomycorrhizas of rubber growing soils of Sri Lanka(Rubber Research Institute of Sri Lanka.
