摘要

PURPOSE: To obtain a nicotiana plant which produces labdan of a high concn. by reproducing matured plants from the calli obtd. by culturing the explants of nicotiana in the presence of the variety of cytokinin, then screening these plants. CONSTITUTION: The explants of the nicotiana, such as nicotiana glutinoza and nicotinana tabacum, are cultured for 2 to 3 weeks on a medium contg. 5 to 20M cytokinin to obtain the calli. The matured plants obtd. by reproducing such calli are screened, by which the variety matured plant generating at least one labdan higher than an average value is obtd.
