Bulb dipping controls Easter lily growth

In a recent issue of HortTechnology, Purdue University researchers Christopher J. Currey and Roberto G. Lopez reported on a study of the effects of a technique called "bulb dipping" on Easter lily. While plant growth retardants (PGRs) are commonly applied as sprays or media drenches, bulb crops can be submerged, or "dipped" in PGR solutions before planting. The experiments were designed to determine if dipping Easter lily bulbs in paclobutrazol solutions would produce a commercially acceptable product. Study results were encouraging; the researchers found that paclobutrazol was effective as a bulb dip.
