盆栽红掌亚丽桑娜催花技术研究

Study on Flower Forcing Techniques of Potted Anthurium andraeanum(Arizona)

[目的]探讨喷施不同浓度的磷酸二氢钾和6苄-基嘌呤对亚丽桑那盆栽苗的催花效果。[方法]以亚丽桑那组培穴盘苗为供试材料,喷施不同浓度的磷酸二氢钾和6苄-基嘌呤对亚丽桑那盆栽苗进行催花试验,测量亚丽桑那植株的花芽分化数、叶片数、花枝直径、花掌长度等生物学性状,研究不同药剂处理对亚丽桑那盆栽苗的催花效果。[结果]喷施3 mg/L的磷酸二氢钾可促进亚丽桑那组培苗提早开花;3 mg/L磷酸二氢钾+20 mg/L 6苄-基嘌呤的处理效果最好,花芽分化早、多,成花率高达90%,花枝长且粗壮;当6苄-基嘌呤浓度为40 mg/L时,亚丽桑那盆栽苗生长受抑制;6苄-基嘌呤对亚丽桑那盆栽苗的叶片黄化有一定的抑制作用。[结论]该试验获得了提高红掌盆栽质量和开花整齐度的技术,提高了国产红掌盆花的规模化种植水平。

[ Objective ] The aim was to discuss the effects of spraying different concn, of potassium dihydrogen phosphate and N6-benzyladenine on flower induction of potted seedlings of Arizona. [ Method] With tissue culture seedlings of Arizona as tested materials, the bloom tests of potted seedlings of Arizona were carried out by spraying different concn, of potassium dihydrogen phosphate and N6-benzyladenine. Some biological characteristics such as the number of bud differentiation, leaf number, flower diameter, the length of flower palm were determined to study the effects of different chemical treatments on flower induction of potted seedlings of Arizona. [ Result ] The application of 3 mg/L potassium dihydrogen phosphate could promote potted seedlings of Arizona to flower earlier; the effect of 3 mg/L potassium dihydrogen phosphate ＋ 20 mg/L N 6-benzyladenine was the best. The flower bud differentiation was early and more, with the flowering rate of 90% , and the flowering branches were long and sturdy ; when N6-benzyladenine was 40 mg/L, the growth of potted seedlings of Arizona was inhibited ; N6-benzyladenine had a certain inhibition on leaf etiolation of potted seedlings of Arizona. [ Conclusion] The technologies of improving the quality of potted seedlings of Arizona and the flowering uniformity were obtained, which increased the level of large - scale cultivation of domestic potted A. andraeanum.
