Control of flowering and bulb maturation in Dendrobium by uniconazol.

叶面喷施烯效唑，控制石斛X粉色娃娃雅致和长春花王的高度和球茎的成熟。在新梢(铅球)上两次喷施12.5 mg/L烯效唑，株高和叶片数降低，茎粗增大。处理植株开花延迟，小花数减少。结果表明，烯效唑处理延缓了铅球的成熟。前期喷施烯效唑的植株次年新梢较短。次年未观察到开花延迟现象。

Uniconazole was used as foliar spray on Dendrobium X Pink Doll Elegance and Yukidaruma King to control height and bulb maturation. When 12.5mg/l uniconazole was applied twice on the new shoots (lead bulb), the plant height and number of leave decreased, on the otherhand stem daiamter increased. Flowering of the treated plants was delayed with lower numbers of florets. The result suggested that maturation of the lead bulb was delayed by uniconazole treatment. Plants treated with uniconazole at earlier stage produced shorter shoots in the following year. No delay of flowering was observed in the following year.
