Postharvest height suppression of potted tulips with paclobutrazol.

Suppression of scape elongation by paclobutrazol and ancymidol in potted Paul Richter tulips under greenhouse and low light postharvest environments was compared. Soil drench applications of paclobutrazol at 0.25 or 0.50 mg/15-cm pot were as effective as ancymidol at 0.50 or 0.75 mg/pot in limiting scape lengths at the coloured bud stage and at senescence. Paclobutrazol pre-plant bulb soaks at 2.5 or 5.0 mg/litre prevented excessive scape elongation during low light exposure, whereas ancymidol bulb soaks were ineffective. Neither growth regulator reduced flower size or affected petal colour. Paclobutrazol applied as a soil drench or as a bulb soak delayed the coloured bud stage by up to 4 days, whereas neither chemical affected post-greenhouse life of tulips.
