摘要
研究应用多效唑调控八仙花2年生组培苗的生长发育,以及利用兰州地区的自然环境条件,在户外自然低温条件下打破花芽休眠,以期将八仙花的花期提前到春节前后。结果表明：7月中旬以质量浓度100-150 m g/L的多效唑溶液对八仙花组织培养苗进行叶面喷施,对其营养生长抑制作用强,有利于其花芽分化。同年11月1日至10日将经过40 d户外自然低温（0-8℃）处理的试验苗移入节能日光温室开始催花,催花起初温度为10℃,以后逐渐升温至25℃左右,春节前正好开花,开花率达到100%,株型美观、花色艳丽,促成栽培效果好且成本低。
Techniques of forcing culture of tissue culture plantlet in Hydrangea Macrophylla Ser. were studied, including Regulating growth and development of 2-year-old one by using PP333 and breaking blossom bud dormancy under natural low temperature condition in Lanzhou, in order to make the H. Macrophylla Set. blooming period reach about Spring Festival. The results showed that spraying leaves by 100-150 mg/L PP333 solution in midJuly, which could strongly inhibit vegetative growth, was favor of flower bud differentiation. In early November, the same year, the test plants treated at low temperature （0-8 ℃） outdoor for over 40 days were transferred into energy-saving sunlight greenhouse for promoting blossom. Temperature of promoting blossom began at 10 ℃, and then gradually rose to about 25 ℃. It blossomed before Spring Festival, and the flowering rate reached 100%, with beautiful plant types, flower color and low cost.
