| Abstrak | Dyera costulata, usually called as jelutung is belonging into Apocynaceae family. This plant is a potential plant species that has good prospect, especially for timber and latex production. However the seedling grows slowly. The experiment was carried out in greenhouse, Treub Laboratory, Botani Division, Centre Research for Biology-LIPI, Bogor, using a Factorial Completely Randomized Design with tree main factors in fi ve replications. The fi rst factor is phase of transplant i.e. seedling with closed cotyledon, seedling with opened cotyledon, seedling with two first leaves. The second factor is growth medias i.e. soil, soil+compost (1:1), soil+husk of rice (1:1), soil+compost+ soil+husk of rice (1:1:1), compost+ soil+husk of rice (1:1). The third factor is mycorrhiza i.e. 0, 2, 4 and 6 g/pot The result showed that the transplant phase had signifi cant effect on the seedling growth. The best of transplant phase is seedling with two leaves which has 100% survival, seedling height 8.57 cm and number of leaves 5.07. Mycorrhiza treatment no signifi cant effect on the seedling growth until 5 months after planting. Growth medias had signifi cant effect at number of leaves. Therefore it is recommended the best media for seedling growth are are of soil+ soil+husk of rice (1:1) , or soil+compost + husk of rice = 1:1:1. There was no interaction effect of transplant phase, mycorrhiza and growth media. |
