Vase life and quality of China aster (Callistephus chinensis) cut flowers as influenced by holding solutions

A study was undertaken on the effect of holding solutions on vase life and quality of China aster cv. Shashank flowers. Holding solutions were found beneficial in increasing vase life and quality of cut flowers over the control (tap water). Maximum vase life (15.88 days) and solution uptake (40.13 ml) was recorded with 8-HQC (200 ppm)+sucrose (1%) over the control (8.42 days and 25.22 ml, respectively). Fresh weight of cut stems increased at 3^rd and 6^th day in vase but declined at senescence. Similar changes were recorded on dry weight also. Maximum increase in flower diameter (7.35 cm) was recorded with AgNO₃ (20 ppm)+citric acid (75 ppm)+sucrose (3%) over the control (5.99 cm). Holding solution containing 8-HQC (200 ppm)+sucrose (1%) was found best in prolonging vase life of China aster cut flowers, followed by 8-HQC (200ppm)+sucrose (2%).
