- 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。
- Abstract:
- 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 ascendant trend with the increasing of shade strength,but under 20% shading treatment,the plants had no significant difference compared with the control;the POD activity increased at first then decreased with the time procong,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.
