Abstract :

Two factorial experiments were conducted to study the interactive effects of four levels of sucrose (0, 20, 40 and 60 g l-1), two levels of citric acid (0 and 160 mg l-1) and two levels of one of the following compounds (aluminum sulphate, 0 and 160 mg l-1 and silver nitrate, 0 and 120 g l-1) on vase life and quality attributes of lisianthus cut flowers ‘Mariachi blue fonce.’ The experiments carried out a randomized complete block design with three replications. After 34 days of storage at 20±2 oC the amount of water absorption, relative water content and opened flower buds were determined. According to the results application of 60 g l-1 sucrose in combination with citric acid led to the highest vase life (31 days). The highest relative water content (82.37%) and also the highest percentage of opened flower buds were obtained in flowers treated with 60 g l-1 sucrose and 160 mg l-1 aluminum sulphate.
