Abstract
Abstract In vitro culture of twin-scaling explants of Galanthus transcaucasicus with different concentrations of plant growth regulators (PGRs) including 0.5, 1, 2, 3, 4, 6, 8, and 10 mg L-1 naphthaleneacetic acid (NAA) and 0.5, 1, 2, 3, and 4 mg L-1 benzyladenine (BA) was studied. After 18 weeks, the number of regenerated bulblets and intensity of callus was measured. Subsequently, bulblets were transferred to a medium with 0.5, 1, 2, 3, and 4 mg L-1 NAA and 0.5, 1, 2, 3, and 4 mg L-1 BA and, after 15 weeks, the bulblets length and diameter were measured. The highest intensity of callus was obtained on 4 mg L-1 NAA or 8 mg L-1 NAA with 1 mg L-1 BA. The highest number of regenerated bulblets was detected with 6 mg L-1 NAA and 2 mg L-1 BA. The highest diameter of bulblets occurred on four mgL-1 NAA (9.4 mm), while the lowest was observed on 0.5 mg L-1 BA (1.83 mm). The analysis of genetic variation using ISSR revealed that there was no somaclonal variation among the regenerated plants from BA and low level of NAA, but there was a significant somaclonal variation at high concentrations of NAA.
