人工栽培条件下,对全光照和遮光处理的醉翁榆和琅琊榆两年生实生苗的形态和生理指标进行测定,结果表明：两种榆树在40%自然光下生长良好,并且醉翁榆在形态上通过增加叶片长度、宽度、叶面积、单叶干重,提高南向枝条比例,在生理上通过增加更多叶绿素含量从而表现出对弱光具有较强的适应能力。

The morphological and physiological indexes of two two-year old elm seedlings were measured under different light intensity in cultivation experiment.The results showed that the two species of elm were adapted to about 40% natural light,and the suitability of the Ulmus gaussenii was better than that of Ulmus chenmoui.The suitability of the two species can be enhanced by increasing the foliar length,width,area and dry weight,and the branches pointing to south,and the chlorophyll content.
