Response of Two Forcing Azalea Cultivars to Bonzi and B-nine Applications
Response of Two Forcing Azalea Cultivars to Bonzi and B-nine Applications
Page Range: 182 – 184
Bonzi (paclobutrazol) sprays of 50, 100, and 150 ppm applied either 1 day before or 1 day after cooling reduced bypass shoot number and length of Dorothy Gish White and Roadrunner azaleas (Rhododendron × ‘Dorothy Gish White’ and R. × ‘Roadrunner’) compared to the control. Flowering was delayed 3 to 8 days depending upon cultivar, rate, and time of application, while bloom diameter was reduced slightly (Dorothy Gish White) or not affected (Roadrunner) by paclobutrazol. B-nine (daminozide) had little effect on either bypass shoot development or flowering of Roadrunner, but reduced flower diameter and· delayed flowering of Dorothy Gish White azalea relative to the control.Abstract
