将生长调节剂0～1%苄基腺嘌呤单独或与0.25%～1%赤霉酸ＧＡ3同时使用,调查其对蝴蝶兰二次放花的影响。结果表明,与对照相比,使用生长调节剂处理后,二次放花期出现率和开花率增加。0.25%苄基腺嘌呤的开花最佳,若苄基腺嘌呤与赤霉酸同时使用,则降低开花率。高浓度的苄基腺嘌呤使 The growth regulator 0 ~ 1% benzyladenine alone or with 0.25% ~ 1% gibberellic acid GA3 simultaneously used to investigate its impact on the second phalaenosis. The results showed that the emergence and flowering rate of second flowering stage increased after treatment with growth regulators compared with the control. 0.25% benzyl adenine flowering the best, if benzyladenine and gibberellic acid used at the same time, then reduce flowering rate. High concentrations of benzyl adenine make
