摘要：采用镝灯人工光源,在温室下对盆栽的14种地被植物进行了光 光相应曲线和二氧化碳(CO2)相应曲线的测定,对比分析了14种地被植物的光补偿点、光饱和点、最大净光合速率、最大表观量子效率、CO2补偿点和RuBP羧化酶的相对活性,并对14种地被植物最大光合速率和最大表观量子效率与植物耐阴性的相关关系及14种地被植物CO2利用能力与耐阴性的相关关系进行了多元回归分析。结果表明:①14种地被植物光能利用特性不同。崂峪薹草Carexcapillariesvar.pohushanensis,荚果蕨Mattescciastruthiopteris,宽叶麦冬Liriopeplatyphylla,萱草Hemerocallisfulva,黄花菜Hemrocalliscitrina,紫花地丁Violaphillipica,玉簪Hostaplantaqinea具有低光补偿点和光饱和点,能够充分利用弱光并具有较强的耐阴性;马蔺Irislacteavar.chinensis,野棉花Anemonehupehensis,白三叶Trifoliumrepens,雪叶菊Seneciobicolor,地被菊Dendranthemagrandiflorum具有较高光补偿点和光饱和点,均为喜光地被植物。②14种地被植物的光补偿点与净光合速率呈正相关,与表观量子效率呈负相关。③地被植物表现出对CO2利用能力的复杂性,光补偿点与CO2补偿点、RuBP羧化酶相对活性的相关性不显著。④具有耐阴能力并由强到弱植物顺序为崂峪薹草、荚果蕨、萱草。
The light-light curve and CO_2 curve of 14 potted ground cover plants,Paeonia lactifolia,Dendranthema grandiflorum,Senecio bicolor,Anemone hupehensis,Hosta plantaginea,Trifolium repens,Viola phillipica,Carex capillaries var.pohuashanensis,Iris lactea var.?chinensis,Hemerocallis citrina,Hemerocallis fulva,Iris tectorum,Liriope platyphylla,and Matteuccia struthiopteris were determined by dysprosium light illumination.Light compensation point(LCP),light saturation point(LSP),net photosynthetic rate(Pn),apparent quanta efficiency (,CO_2 compensation point and RuBisco relative activity of these plants were analyzed comparatively.The correlations of shade tolerance with Pn,Φ and CO_2 utilization ability were discussed by multi-factor analyzing.The results showed that different ground cover plant had different light utilization characteristics.Viola phillipica,Hemerocallis citrina,Hemerocallis fulva,Liriope platyphyllus,Matteuccia struthiopteris,Carex capillaries var.pohuashanensis,and Hosta plantaginea had lower LCP,meanwhile they had lower LSP.They can use low light quantum,and have strong shaded-tolerance.Iris tectorum,Iris lactea var.chinensis,Senecio bicolor,Dendrenthema grandiflorum,Anemone hupehensis,Trifolium repen had higher LCP and LSP,and were sun ground cover plants.A significantly positive correlation was found between LCP and Pn,LCP and RuBisco relative cutivity.A negative correlation was found between LCP and Φ.The order of ability to shade-tolerance of ground cover plants is Carex capillaries var.pohuashanensis>Matteuccia struthiopters>Hemerocallis fulva>Liriope platyphyllus>Hemerocallis citrina>Viola phillipica>Iris tectorum>Hosta plantaginea.
