Effect of postharvest preservatives on vase life of cut rose (Rosa hybrida L.) cv. top secret

Abstract

The research experiment was laid out in completely randomized design with three replication and fourteen treatments like Control, Sucrose (2.0%), Silver Nitrate (30 ppm), Silver Nitrate (60 ppm), Boric Acid (75mg/l of water), Boric Acid (100mg/l of water), Sucrose (2.0%) + Silver Nitrate (30 ppm), Sucrose (2.0%) + Silver Nitrate (60 ppm), Sucrose (2.0%) + Boric Acid (75mg/l of water), Sucrose (2.0%)+ Boric Acid (100mg/l of water), Sucrose (2.0%) + Silver Nitrate (30 ppm) +Boric Acid (75mg/l of water), Sucrose (2.0%) + Silver Nitrate (30 ppm) + Boric Acid (100mg/l of water),Sucrose (2.0%) + Silver Nitrate (60 ppm) + Boric Acid (75mg/l of water), Sucrose (2.0%)+ Silver Nitrate (60 ppm) + Boric Acid (100mg/l of water) were used for experiment. Data revealed that the treatment T11 (Sucrose 2.0% + AgNo3 30 ppm + Boric Acid 75 mg/l of water) recorded the best performance with respect of days taken to 1st petal spreading, change in weight of flowers at senescence, flower freshness score, maximum flower head diameter, petal discoloration score, change in TSS, change in chlorophyll content, change in anthocyanin content and vase life.
