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.

烯效唑作为叶面喷雾剂用于石斛X粉红娃娃优雅和Yukidaruma国王，以控制高度和鳞茎成熟。12.5mg/L烯效唑对新梢（铅鳞茎）喷施2次，株高和叶片数下降，茎粗增加。处理植物的开花延迟，小花数量减少。结果表明，烯效唑处理可延缓铅球的成熟。在早期用烯效唑处理的植株在第二年产生较短的枝条。第二年没有观察到开花延迟。
