STUDIES ON CUT-FLOWER SELECTIONS OF SPIRAEA AND LANDSCAPE USE
Spiraea is a genus of beautiful ornamental plants with colorful flowers and strong ecological adaptability.
The objective of this study is to provide scientific bases for cut flower selection and the use of Spiraea as a landscape plant.
The usefulness as cut-flower selections was studied on six species (S. trilobata, S. dasyantha, S. salicifolia, S. japonica, S. fritschiana, and S. pubescens) in different standard vase solutions at 20-25°C (1% sucrose + 50 ppm 8-hydroxyquinoline (A), 1% sucrose + 1% ethanol + 50 ppm 8-HQ (B), 2% sucrose + 20 mg/L silver nitrate + 50 ppm 8-HQ (C) and tap water (D). Vase-life was prolonged by solutions A and B compared to tap water, with an average of 8.0, 8.6, and 6.5 days, respectively.
Branches of S. dasyantha had 100% flowering but only 6.9 days average vase life.
The cut branches of S. japonica had 100% flowering and an average vase life of 10.8 days, indicating its potential as a cut flower.
The application of Spiraea in Beijing landscapes was assessed.
The S. × bumalda Goldmound, S. japonica and S. thunbergii were the most common species in the gardens visited.
