摘要
为了解黄金香柳生理指标与光照条件的关系,研究了不同遮荫处理(20%、40%、60%、全光照)下黄金香柳的生理特性的变化。结果表明:随着遮荫强度的增加和时间的延长,黄金香柳可溶性糖含量先降低后上升,可溶性蛋白质含量呈上升趋势;MDA含量随遮荫强度的加剧而增大,但20%遮荫处理与对照差异不大;随着胁迫时间的延长,POD含量先升高后降低,20%和40%遮荫下POD活性均高于对照。表明黄金香柳对一定程度的遮荫处理具有一定程度的适应能力,夏季高温季节以20%和40%遮荫为宜。
In order to reveal the relationships between different light intensities and changing of physiological characteristics of Melaleuca bracteata cv .Revolution Gold ,the effect of shading by four levels （20% ,40% , 60% ,full light） on physiological characteristics was studied .The results indicated that with the increasing of shade strength and time ,the soluble sugar content increased after a first decreased ,the soluble protein content showed a increasing tendency ;the POD content increased at first then decreased ,the MDA content showed as‐cendant trend with the increasing of shade strength ,but under 20% shading treatment ,the plants had no signif‐icant difference compared with the control;the POD activity increased at first then decreased with the time pro‐cong ,under 20% and 40% shading treatment ,the POD activity was higher than the control .It could endure certain extent shading ,20% and 40% shading treatments were good choice in summer .
