Seleksi Kekeringan In Vitro Enam Belas Nomor Tanaman Terung (Solanum melongena. L) dengan Polietilena Glikol (PEG)

Abstract

The objectives of this study were to study the effect of several concentrations of polyethylene glycol (PEG) on the in vitro growth of eggplant, to find the appropriate PEG concentration for in vitro selection to drought resistance of eggplant and the drought tolerant eggplant accessions. The experiment was conducted at the Laboratory of Tissue Culture, Department of Agronomy and Horticulture, Bogor Agricultural University. The experiment was laid on a completely randomized design with two factor. The first factor was concentration of PEG ( 0, 5, 10, and 15% ) while the second factor was eggplant accessions (Kania F1, 001, 007, 013, 016, 030, 034, 035, 055, 057, 069, 071, 072, 078, 085, and 090 ). The results showed that the addition of PEG to in vitro media significantly affected the survival percentage, the percentage of callus, developed the bud and the number of leaves of eggplant. Addition of PEG 10 and 15% in media can be used as the drought resistance selective agent of eggplant in vitro. Kania F1, 001, 007, 016, 034, 035, 055, 057, 069, 071, 072, 078, 085, and 090 were eggplant accessions which might be tolerant to drought resistance.
