以浙江产野海棠属3种野生花卉为研究对象,采用LI-6400便携式光合仪测定其光合特性,并进行比较分析,以期为其在园林上的应用提供理论依据。结果表明:3种野海棠均具有较好的利用光强的能力,以方枝野海棠的光合能力最强;光饱和点均在900μmol/m2.s以上,光补偿点均在20μmol/m2.s以下,说明3种野海棠均具有较强的耐阴性,适合布置于园林花境中较阴凉处。
In this paper, three wild flowers of genus Begonia from Zhejiang Province were selected as research objects. Their photosynthetic characteristics were measured by portable photosynthesis apparatus LI-6400, and comparative analysis was carried out to provide a theoretical basis for their application in gardens. The results showed that all three species of wild crabapple had the best ability of using light intensity, and the photosynthetic capacity of the wild branch crabapple was the strongest. The light saturation points were above 900μmol / m2.s and the light compensation points were both 20μmol / m2.s The following, indicating that three kinds of Wild Begonia have strong resistance to negative, suitable for arrangement in the garden flowers in the shade.
