Abstract
The effect of different shading levels on leaf area and chlorophyll contents of Hosta plantaginea were studied.Using urban greening of Hosta plantaginea as the research object,under three different shading levels with full shade(20% to 30% full sunlight),semi-shade(50%to 60% full sunlight)and 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 enlarges;the content of chlorophyll a and b increased,but the increase rate of chlorophyll b was larger than chlorophyll a;chlorophyll a/b value decreased.Hosta plantaginea were strongly able to endure shade,suitable for indoor furnishings and a large crown density garden configuration.
