ABSTRACT
An experiment was conducted to find out the preservative solution for extending the vase life of cut rose (Red pearl cultivar). Ten chemical preservative solutions were used for vase life analysis and these were T0: Tap water (Control); T1: Sugar (50-ppm); T2: Citric Acid (50-ppm); T3: Salicylic Acid (50-ppm); T4: Chitosan (50-ppm); T5: Silvar Thiosulphate (50-ppm); T6: Sugar + Citric Acid (50-ppm); T7: Sugar + Salicylic Acid (50-ppm); T8: Sugar + Chitosan (50-ppm) and T9: Sugar + Silvar Thiosulphate (50-ppm). From the experiment, maximum stem diameter (4.60 mm), period for first petal spreading (6.1 days), petal water content (65.4%) and vase life (15.7 days) was found from T7. On the other hand, minimum flower head diameter (31.8 mm), petal discoloration score (1.5) and flower freshness score (3.0) were also found from T7. Combined application of sugar and salicylic acid was the best among the chemicals used for extending vase life of cut rose cv. Red pearl.
Key words: Rose, chemical preservatives and vase life
