Mexican redbud (Cercis canadensis var. mexicana) shoot cultures were initiated from explants taken from both mature and juvenile stock plants. Culture conditions affecting shoot growth and proliferation and rooting of three clones were investigated. Shoot growth was best on media supplemented with 0.25% activated charcoal and solidified with 0.2% Gelrite. Four commercially available salt formulations (Anderson's rhododendron medium, WPM, MS, DKW) were tested for growth of shoot cultures, and Anderson's rhododendron basal salt mixture was superior. Axillary shoots grew from explants cultured media supplemented with a wide range of concentrations of benzyladenine and thidiazuron. Benzyladenine at 5.6-22.2 μM supported the best combination of shoot quality and number. Rooting of microshoots in vitro was best on half-strength WPM containing 6.71 μM naphthaleneacetic acid and 0.1% activated charcoal.
