Abstract
The effect of different shading levels on leaf area and chlorophyll contents of Ophiopogonis japonicus were studied.Taking urban greening of ophiopogonis japonicus as the research object,under three different shading levels with full shade(25% to 45% full sunlight),semi-shade(60% to 80% full sunlight),no shading(full sunlight),the size of leaf area,the content of chlorophyll a and b,and chlorophyll a /b value were measured and analyzed.The results show that,with the degree of shading increasing,leaf area enlarged,the content of chlorophyll a and b increased,but the increase rate of chlorophyll b was larger than chlorophyll a,and the chlorophyll a /b value decreased.Ophiopogonis japonicus is strongly able to endure shade,is suitable for indoor furnishings and a large crown density garden configuration.
