High efficiency shoot regeneration from callus of quaking aspen (Populus tremuloides Michx.).

Academic Article

Abstract

  • Callus was induced from leaf segments of aspen (Populus tremuloides Michx.) on modified B5 (mB5) medium with 0.1 mg/1 benzyladenine (BA) and 0.5 mg/1 2,4-dichlorophenoxyacetic acid (2,4-D). The resulting callus was either subcultured to solidified Woody Plant Medium (WPM) with 0.5 mg/1 BA directly for shoot regeneration or sieved into liquid mB5 medium for suspension culture. After 3 weeks of suspension culture, when the callus clumps grew to 3-4 mm in diameter, they were transferred onto solidified WPM with 0.5 mg/1 BA for shoot regeneration. Almost 100% of the clumps formed shoots on WPM when subcultured directly from mB5 with an average number of 6 shoots per callus. When transferred from suspension culture in mB5 to WPM, an average of 6 shoots per callus were produced from 51% of calli. These shoots could be easily rooted on either mB5 or WPM with 0.2 mg/1 indole-3-butyric acid (IBA) and transferred to pots. Transplanted plants were kept under intermittent mist for 2-4 weeks before normal growth in the green house.
