外源激素对微型蝴蝶兰双梗发生率及花梗发育的影响

Effects of Exogenous Hormones on the Incidence of Double Stems and Pedicel Development of Miniature Phalaenopsis amabilis

摘要: 以微型蝴蝶兰“绿熊”“粉佳人”“甜格格”3个品种为材料，开展不同浓度外源激素叶面喷施试验，探究其双梗发生率和花梗发育状况。结果表明，“绿熊”在6-BA 200 mg/L处理下出梗率100%;“粉佳人”在6-BA 150 mg/L处理下出梗率为100%,中KT-30 150 mg/L处理下出梗率为90%;“甜格格”在6-BA 150 mg/L处理下出梗率为100%,GA₃ 150 mg/L处理下出梗率为100%,KT-30 150 mg/L处理下出梗率为90%。因品种差异，各品种花梗对外源激素敏感度、发育时间有所不同。

Abstract: Using three varieties of miniature Phalaenopsis amabilis Green Bear, Pink Beauty and Sweet Gege as materials, foliar spraying experiments with different concentrations of exogenous hormones were carried out, the incidence of double peduncles and the development of pedicels were explored. The results showed that Green Bear variety treated with 6-BA 200 mg/L stem rate was 100%; The stem rate of Pink Beauty variety treated with 6-BA at 150 mg/L was 100%, followed by KT-30 at 150 mg/L with a stem rate of 90%;The stem rate of Sweet Gege was 100% at 6-BA 150 mg/L, 100% at GA₃ 150 mg/L, and 90% at KT-30 150 mg/L. Due to species differences, the sensitivity of pedicels of various varieties to exogenous hormones, development times varied.
