Plantlet Regeneration via Somatic Embryogenesis from Hypocotyls of Common Buckwheat (Fagopyrum esculentum Moench.)

DOI : 10.7740/kjcs.2013.58.4.331

Buckwheat sprout is used as vegetable, and also flour for making noodles, and so on. Currently, information about tissue culture in buckwheat is limited and restricted to micro-propagation. We carried out somatic embryogenesis and plant regeneration using hypocotyl segments as explant of the cultivated buckwheat species, Fagopyrum esculentum which differs from existing studies in the growth regulator combin-ations used. Maximum callus regeneration was induced on MS medium containing 2,4-dichlorophenoxyacetic acid (2,4-D) 2.0 mg · L-1, benzyladenine (BA) 1.0 mg · L-1 and 3% sucrose. Friable callus was transferred to solidified MS media containing BA (1.0 mg · L-1) with various concentrations of 2,4-dichloro-phenoxyacetic acid for the induction of embryogenesis. The optimum concentrations of growth regulators (for regeneration of plantlet) were indole-3-acetic acid (2.0 mg · L-1), Kinetin (1.0 mg · L-1), BA (1.0 mg · L-1). Only 2,4-D did not show any significant effect on callus induction or embryogenesis. Regeneration of embryonic callus varied from 5% to 20%. Whole plants were obtained at high frequencies when the embryogenic calli with somatic embryos and organized shoot primordia were transferred to MS media with 3% sucrose. The main objective of this research was to develop an efficient protocol for plant regeneration for common buckwheat, and to apply in future for genetic transformation.
