| 摘 要： | 以风信子品种‘蓝夹克’为供试材料研究了叶面喷施不同浓度的多效唑(PP333)对风信子生长和开花的影响,研究结果表明叶面喷施100 mg/L的PP333延缓‘蓝夹克’的生长,使植株适量矮化、叶面积适度减小,植株更紧凑;与对照相比,叶片厚度增加了5.8%,小花直径增加了2.8%,种球质量增加了5.3%。同时提高了植株叶片的叶绿素含量,将现蕾时间推迟4天,并使花期延长4天,总体上提高了‘蓝夹克’的观赏价值。叶面喷施300 mg/L的PP333因浓度较高,表现出一定的抑制作用。

| Abstract: | Through foliar spraying of different concentrations of paclobutrazol solution,the effects of paclobutrazol on growth and flowering of Hyacinthus orientalis ’Blue Jacket’ were studied.The results showed as follows: foliar-spraying of 100 mg/L of paclobutrazol solution was the best treatment.It decreased the growth rate,plant height and leaf area moderately.Compared to the control,the leaf thickness,flower diameter and weight of bulbs increased by 5.8%,2.8% and 5.3% respectively.At the same time,foliar-spraying of 100 mg/L of paclobutrazol solution significantly increased the chlorophyll content in leaves.It delayed the appearance of flower buds for 4 days,prolonged the florescence for 4 days,and put off the senescence of hyacinth.Foliar-spraying of 300 mg/L of paclobutrazol solution showed negative effects because of the high concentration. |
