摘要：Carica pubescens Lenne & K. Koch is a rare species that need to be conserved. The research aim was to develop a slow growth method of in vitro conservation medium through determining some effects of nutrition decreasing availability in the conservation medium on growth and survival of explants. Establishing epicotyls reached from in vitro seed germination was grown on diluted basic medium of 75% MS (Murashige and Skoog), 50% MS, 25% MS, while osmoregulator compound of mannitol and sorbitol was added to the full MS medium in several concentrations. The treatments were arranged in a completely randomized design with three replications. The epicotyls were grown at storage medium for 12 and 16 weeks, then their survival were evaluated at regeneration medium and rooting medium. The diluted basic medium and osmoregulator addition were evaluated for its influence in retarding the culture growth in terms of improved survival over the period of 16 weeks. Data analyzed by one way analysis of variance and Duncan’s multiple range test. The results showed that the decreasing of nutrition concentration suppressed the growth of the epicotyls until 16 weeks after conservation. Epicotyls taken from 16 weeks after conservation could grow on the regeneration medium. The best survival was shown by the 75% MS, 50% MS and supplementing of 20 g/l mannitol treatments. Based on these results, 50% MS medium is recommended for storage C. pubescens for 16 weeks with no sub-culture.
