Effect of BAP concentration on the growth of several types of rambutan plants (Nephelium lappaceum L.) in vitro

Abstract

Abstract In vitro seed propagation is needed as an alternative to providing superior rambutan planting material. This research aimed to examine the effect of BAP on the growth of several varieties of rambutan in vitro. The method used was a completely randomized design with 2 factors, the first factor was rambutan varieties (binjai, rapiah, and ace), and the second factor was BAP concentrations (0, 2, 4, and 6 ppm). There were 12 treatment combinations and 3 times replications. Variables observed was analyzed using analysis of variance followed by 5% Duncan’s Multiple Range Test and other data (leaf emergence time, number of leaves, root emergence time, number of roots, and root length) were analyzed descriptively. The results showed that the combination of 0 ppm BAP and binjai variety gave the best results on the shoot length, number of leaves, and number of roots. The 0 ppm BAP treatment gave the best results on the number of shoots, shoot length, number of leaves, number of roots, and root length. Binjai variety treatment gave the best results on the time of shoot emergence, shoot length, time of leaf appearance, number of leaves, time of root appearance, and number of roots.
