ORGANOGENESIS TANAMAN BAMBU PUTIH (Bambusa glaucophylla Widjaja) DENGAN PENAMBAHAN ZAT PENGATUR TUMBUH BAP (Benzyl Amino Purine) DAN IBA (Indole Butiric Acid) SECARA IN VITRO

Tissue culture is an alternative solution to the problem of getting white bamboo (Bambusa glaucophylla Widjaja) seeds in large quantities in a short time. In addition, the addition of auxin and cytokine growth regulators is one of the determining factors in the success of tissue culture. The aim of the study was to determine the best combination of BAP (Benzyl Amino Purine) and IBA (Indole Butiric Acid) for the organogenesis of white bamboo (B.glaucophylla Widjaja) in vitro. The study was conducted in a forestry science laboratory from September to December 2017. This study used a completely randomized design (CRD) consisting of 4 treatments, namely: P1 = MS + 2 ppm BAP + 0.2 ppm IBA, P2 = MS + 2.5 ppm BAP + 0.2 ppm IBA, P3= MS + 2 ppm BAP + 2.5 ppm IBA, P4= MS + 2.5 ppm BAP + 2.5 ppm IBA. Each experiment was repeated 6 times, so there were 24 experimental units. The parameters observed were when the tuna appeared, the number of tuna, when the leaves appeared, the number of leaves and the number of roots. Data were analyzed quantitatively using analysis of variance. The results showed that the best combination of growth regulators BAP and IBA was found in P4 treatment with a concentration of MS + 2.5 ppm BAP + 2.5 ppm IBA providing the highest number of tuna with an average of 1.83 tuna, inducing the fastest leaves with an average of 1.83 tuna. an average of 1.58 Days After Planting (DAT), and the highest number of leaves with an average of 1.83 strands. At the end of the observation no roots were formed in all the treatments tried.Kata Kunci : Organogenesis, BAP, IBA, In Vitro, Bambusa glaucophylla Widjaja
