研究了观叶植物长心叶蔓绿绒的光合特性。结果表明，该植物属于典型的荫生植物，单位叶重的叶绿素含量较低，叶绿素ａ／ｂ比值较低。通过测定光合速率对光强的响应，应用计算机模拟求得：光补偿点为４３１７μｍｏｌ·ｍ－２·ｓ－１，光饱合点为６２６９８μｍｏｌ·ｍ２·ｓ－１，最大光合速率为５３６８μｍｏｌ·ｍ－２·ｓ－１。
The photosynthetic characteristics of the chlorophyll content of the evergreen leaves of the foliage plant were studied. The results showed that this plant belongs to a typical shade plant, with lower leaf chlorophyll content and lower chlorophyll a / b ratio. By measuring the response of photosynthesis rate to light intensity, the computer simulation was used to find that the light compensation point was 4317μmol · m-2 · s-1 and the light saturation point was 62698μmol · m2 · s-1. The maximum photosynthesis The rate was 5368μmol · m-2 · s-1.
