采用不同浓度的植物生长延缓剂多效唑与比久对盆栽2年生日香桂进行叶面喷施处理,研究不同处理对日香桂矮化的影响。结果表明:在适宜浓度梯度范围内,随着植物生长延缓剂施用量的加大,矮化效果增强,新枝高生长量明显受到抑制,节间长度缩减,地径增粗,根冠比增加,根系活力提高,叶色变浓绿,叶绿素含量提高。但过高浓度矮化剂处理会产生药害现象。经药效综合评分法确定,500 mg/L 多效唑和3 000 mg/L 比久对日香桂的矮化效果最好。
Abstract
This experiment studied the dwarfing effect of different concentration of paclobutrazol(PP333)and daminozide on two-year-old potted Osmanthus fragrans‘Rixiang Gui’. The result showed that in a proper concentration range, the dwarfing result of these two plant growth retardants at a high concentration was better than at a low concentration. In a proper concentration range, increment of new branches height was inhibited, the internodes length was shortened, at the same time, the ground diameter, root shoot ratio and root vigor were increased, also, the leaves turn dark green, and the chlorophyll contents was added. But too high concentration leads to phytotoxicity phenomena, bad to oramental value of ‘Rixiang Gui’. By using comprehensive evaluation method, a conclusion was drawn that 500 mg/L paclobutrazol and 3 000 mg/L daminozide treatments could effectively dwarf the growth of ‘Rixiang Gui’.
