The effect of carbon source on plant regeneration in tomato

Abstract

The effect of different tomato cultivars and different sugar types (sucrose, glucose and maltose) and concentrations (1.0, 2.0 and 3.0%) on shoot regeneration from aseptically grown hypocotyl and cotyledon explants were studied. Among sugar types, sucrose at a concentration of 3.0% induced the highest number of shoots from both types of explants. In hypocotyl explants, cv. Premium showed the best regeneration capacity (0.23 shoots per explant), and in cotyledon explants, cv. Hana produced the maximal number of shoots (0.43 or 0.37 for media with 2.0% or 3.0% sucrose, respectively).
