采用植物生长延缓剂多效唑(PP333)、烯效唑(S3307)、矮壮素(CCC)喷施和灌根的方法对1~3年生盆栽金钱树的矮化效应进行研究. 结果表明:PP333能明显使叶轴矮化,小叶间距缩短,叶柄基部变粗,复叶相对生长速率降低;S3307主要使叶柄基部变粗;CCC药效表现不稳定,对部分指标表现出了促进作用. 不同年龄金钱树适宜的PP333浓度变化大,S3307浓度变化小. 喷施或灌根的矮化效果基本一致. 药害在灌根处理上较同浓度喷叶处理更严重. 综合考虑金钱树的生长及观赏价值,对不同年龄金钱树应用植物生长延缓剂调控株形效果好的组合有:1年生苗用300mg·L-1S3307喷叶处理;2年生苗用300mg·L-1S3307灌根处理或600mg·L-1...

The effects of three plant growth retardants paclobutrazol（PP333）,uniconazole（S3307） and chlorcholinchlorid（CCC） and two methods of application（foliar spray and root drench） were studied on Zamioculcasz amiifolia plants of ages one,two and three years.PP333 and S3307 both significantly inhibited growth and their effects increased as the concentration applied increased.However,CCC did not significantly inhibit growth.PP333 reduced the average total length of leaf stalks,minimized the length petiolules（i.e.the stalk between leaflets）;sh...
