摘　　要：以"黑美人"、"玛格瑞特"、"三色薯"、"卡罗琳铜"4个观赏甘薯品种为试材,研究了未遮阴(100%自然光,CK)、轻度遮阴(75%自然光)、中度遮阴(50%自然光)、重度遮阴(25%自然光)等遮阴处理对观赏甘薯光合特性的影响。结果表明:"黑美人"的耐阴性最强,"玛格瑞特"和"三色薯"耐阴性较强,"卡罗琳铜"耐阴性最差。Taking four ornamental sweetpotatos as material, the effect of full sunshine（100% natural light, CK）, light shading （75 % natural light）, medium shading （50 % natural light） and severe shading （25 % natural light） on ornamental sweetpotato photosynthetic characteristics were studied. The results showed that the shade tolerance of Iporrmea batatas ＇Black Beauty~ was the best,the shade tolerance of Ipomoea batatas ＇Magarite＇ and Ipomoea batatas ＇Tricolor＇ was strong,and the shade tolerance of Ipomoea batatas ＇Sweet Caroline Bronze＇ was the worst.
