Propagation In Vitro of Rose

David R. Wilkowske* - Department of Horticulture, University of Minnesota, St. Paul, MN  55108.

Abstract 474 - Collegiate Branch Forum II

Photo of PersonCultured lateral buds from greenhouse-grown rose (Rosa hybrida L. cv. Forever Yours) proliferated multiple shoots using McGown's Woody Plant Medium (WPM) supplemented with 6-benzylamino purine (BA) at 2.0 mg/liter and naphthalene-acetic acid (NAA) at 0.1 mg/liter. A 3-fold multiplication of shoots was achieved from freshly explanted lateral buds after 4 weeks. Reculture of the 4 week old explants onto WPM (without NAA) resulted in a 3-6 fold increase 4 weeks later. Longer shoots were then transplanted into a potting soil and placed in a high humidity growth chamber for 3 weeks after which rooting was achieved on 20% of the shoots.
