- 摘要:
- 以药用植物薄荷作为研究对象,利用PAM-2500便携式调制叶绿素荧光仪对其叶片荧光特性在春季的动态变化进行了研究。结果表明:月份、时刻及其交互作用对薄荷的荧光特性会产生显著性影响(P<0.05);薄荷的各项荧光参数在春季的3个月中变化趋势基本一致,不同时刻间存在显著性差异(P<0.05),且基本上5月份的各值最大,4月份次之,3月份最小;其中,最大荧光(Fm)与光化学效率(Fv/Fm)在春季的日变化趋势一致,而光化学淬灭系数(qP)和非光化学淬灭系数(qN)的日变化趋势则刚好相反。
- Abstract:
- Taking medicinal plants Mentha haplocalyx as materials,controlled experiments were conducted to investigate the chlorophyll fluorescence characteristics variation of leaves in spring by using PAM-2500 portable modulation chlorophyll flurescence spectrometer.The results showed that month,time and their interaction significantly affected chlorophyll fluorescence characteristics variation of Mentha haplocalyx leaves(P<0.05).Fluorescence parameters of Mentha haplocalyx had the same change trend in the three months of spring,significantly differences existed on the different time (P<0.05),and basically,values of fluorescence parameters in May>April>March.Trends of Fm and Fv/Fm in spring were similar to each other,otherwise,trends of qP and qN were different to each other.
