Abstract:
Ligustrum vicaryi and Euonymus kiautschovicus were used as the experimental material to study the effects of light intensity of 8%,20%,50% and 100% on photosynthetic characteristics and chlorophyll fluorescence parameters by shading method.In order to discuss their adaptability to low light environment.The results showed that with the increment of shading the plant height,leaf area,the water content and the chlorophyll content increased,while the leaf thickness,specific leaf weight and chlorophyll a/b decreased of the two shrubs.The net photosynthetic rate (Pn),transpiration rate (Tr)基,stomatal conductance (Gs) first rised and then fell,intercellular CO2 concentration(Ci)decreased.Shading increased the maximum photochemical efficiency (Fv/Fm)of the photosystem Ⅱ (PSⅡ)基 increased,the actual light energy conversion efficiency(Fv′/Fm′)of Ligustrum vicaryi PSⅡ基 decreased,that of Euonymus kiautschovicus (Fv′/Fm′) increased.The non-photochemical quenching coefficient (NPQ) of Ligustrum vicaryi significantly increased,and the NPQ of Euonymus kiautschovicus significantly decreased.Shading improved the apparent quantum efficiency (AQY) and decreased the light compensation point (LCP) of the two shrubs, Ligustrum vicaryi reached up to the maximum net photosynthetic rate (Pnmax基) and light saturation point (LSP) under 20% shading treatment,and Euonymus kiautschovicus reached at 50% shading treatment.The two shrubs showed strong adaptability to different light environments and had certain ability to adapt to the weak light environment.
