Pengaruh Mikoriza, Media Tanam Dan Fase Transplant Terhadap Pertumbuhan Bibit Jelutung (Dyera Costulata (Miq.) Hook.f)

Dyera costulata, usually called as jelutung is belonging into Apocynaceae family.This plant is a potential plant species that has good prospect, especially for timberand latex production. However the seedling grows slowly. The experiment wascarried out in greenhouse, Treub Laboratory, Botani Division, Centre Research forBiology-LIPI, Bogor, using a Factorial Completely Randomized Design with treemain factors in five replications. The first factor is phase of transplant i.e. seedlingwith closed cotyledon, seedling with opened cotyledon, seedling with two firstleaves. The second factor is growth medias i.e. soil, soil+compost (1:1), soil+huskof 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 thatthe transplant phase had significant effect on the seedling growth. The best oftransplant phase is seedling with two leaves which has 100% survival, seedlingheight 8.57 cm and number of leaves 5.07 . Mycorrhiza treatment no significanteffect on the seedling growth until 5 months after planting. Growth medias hadsignificant effect at number of leaves. Therefore it is recommended the best mediafor seedling growth are are of soil+ soil+husk of rice (1:1) , or soil+compost + huskof rice = 1:1:1. There was no interaction effect of transplant phase, mycorrhizaand growth media

Karakteristik, Klasifikasi Tanah, Dan Pertumbuhan Tanaman Jati (Tectona Grandis Linn F.) Var. Unggul Nusantara Di Ciampea, Kabupaten Bogor

Teak (Tectona grandis Linn f.) produce one of the most desirable wood in the world. Nowadays, fast growing teak resulting from genetically engineered teak have been available. This study aims to look at the relationship between land characteristics and soil classification with vegetative growth of “Unggul Nusantara” varieties of teak. The study was conducted in Ciampea, Bogor Regency. Soil properties were analyzed from three profiles, while the vegetative growth of teak was measured from 2.5-3 years old teak planted on those land. The diversity of soil properties on the profiles were function of the difference of soil parent material as well as its position on the slopes. Three soil profiles of P-1, P-2, and P-3, lying from upslope to the downslope, were classified respectively as Typic Paleudalf, very fine, mix, active, isohipertermic; Typic Dystrudept, very fine, mix, active, isohipertermic; and Typic Hapludult, very fine, mix, semi-active, isohipertermic. Soil of the three profiles were capable of supporting the growth of teak varieties of “Unggul Nusantara”. The best grown plant was found on the profile P-1 in the upslope, followed by the plant on the profile P-3 in the downslope, and then the plants on land above the P-2 in the middle slope. Nevertheless, the quality of the teak harvest produced in the three profiles can be categorized as low category. Soil with lime sediment parent material that has a high pH and base saturation is able to provide better growth for plants teak varieties of “Unggul Nusantara”
