Elephant yam {Amorphophallus paeoniifolius (Dennst.) Nicolson} can be developed as food for diversification in Indonesia. The main obstacle is in propagation, due to long period dormancy of tuber and slow life cycle. Study on propagation of elephant yam was conducted in of Bogor Botanical Garden nursery. The aims of this study are to propagate elephant yam using tuber and rachis cutting manipulated with Plant Growth Regulators (PGR) respectively to break dormancy and to obtain an effective and efficient propagation method. PGR used in tuber cutting (small adjacent tuber and sliced-bulb) is GA3 10 ppm, GA3 20 ppm, IBA 10 ppm, IBA 20 ppm, BAP 10 ppm, BAP 20 ppm and control with or without burned husk, meanwhile PGR used in rachis cutting (R1, R2 and R3) is BAP 1 ppm, NAA 1ppm, and Rootone-F 1600 ppm. Propagation with tuber showed that IBA, GA3, control, and BAP gave similar result in developing bud numbers. Propagation with small adjacent tuber gave better result in sprouting number. Propagation with small adjacent tuber and manipulated with GA3 resulted highest sprouting number. Rootone-F 1600 ppm caused death, meanwhile BAP, NAA, and their combination (BAP-NAA) had no influence on rachis cutting growth. Lower doses Rootone-F, BAP, NAA, and BAP-NAA higher doses, rachis cuttings from juveniles are recommended.

PERBANYAKAN VEGETATIF BIDARA UPAS (Merremia mammosa (Lour.) Hallier f) KEBUN RAYA BOGOR [Vegetative Propagation of Bidara Upas ( Merremia mammosa (Lour.) Hallier f)) at Bogor Botanical Garden] Cahyaningsih, Ria; Hidayat, Syamsul; Hidayat, Endang

Bidara upas (Merremia mammosa (Lour.) Hall.f.) is a medicinal plant, , that traditionaly use byÂ Indonesian and Malaysian people. Regarding Indonesia Biodiversity Strategy and Action Plan released by The National Development Planning Agency, it is included in the extinct medicinal plant list (2003). As the center for plant conservation, Bogor botanical garden conducted vegetative propagation study on this plant by air layering, cutting, and tuber cutting. The aim to this study is to find effective for bidara upas which method is vegetative propagation. Air layering and cutting propagation modified by Rootone-F did not give any result, whereas tuber cutting propagation with GA3 gave positive result. Principally, propagation by tuber cutting modified by 50 ppm of GA3 dose gave the most rapid and highest uniformity on shoot emergence, the best on growing variables, namely average height of shoot growing, the number of secondary roots, the number and length of the primary roots. It cannot be concluded yet that propagation by tuber cutting modified by GA3 was the most effective. Hence, it is necessary to conduct another propagation studies of air layering and cuttings with more variants of treatments, especially Rootone-F dose.
