Abstract

Evidence for population-density effect on shoot and root growth was obtained through asparagus lateral bud culture. This effect may be due to some diffusing substance or substances from explants on the medium, and can be replaced with various cytokinins; kinetin, 6-benzylamino-9-(2-tetrahydropyranyl)-9H-purine (SD 8339) and benzyladenine provided with naphthaleneacetic acid (NAA).
Good root growth was observed when explants were transplanted from modified Murashige and Skoog′s medium (the basal medium) containing 0.3mg/l NAA and 0.1 mg/l kinetin to the basal medium. The optimum root-inductive period on the basal medium containing NAA and kinetin was 2-3 weeks.
