Abstract:

To screen out the suitability for landscape greening in Tianjin coastal area, 26 varieties of test materials with good growth conditions and strong stress resistance were selected from 36 varieties of Hydrangea macrophylla. 9 indexes of branches, leaves, and flowers were studied with the application of the grey correlation analysis. The results showed that significant differences in weighted correlation value among 26 varieties of Hydrangea macrophylla were detected, which ranged from 0.479-0.834. Six varieties including Taube, Utaawase, Forever Summer, Temari and Ivetta had higher relative correlation values (>0.7), which means strong ecological adaptability and outstanding ornamental value in this area. These excellent ornamental varieties could be used as high-quality provenances for further research and promotion on the landscaping of Tianjin coastal area.
