Cut flowers of rose cv. First Red were harvested in October month for two consecutive years. After precooling these at 2° C for an hour, stems were trimmed to 45 cm and one set of flowers were pulsed with various solutions for 12h and another set of flowers for 24 h. The results revealed that pulsing of cut rose cv. First Red stems with 200ppm 8-HQC + 3 per cent sucrose for 24 h resulted in maximum vase life (20.28 day), flower diameter (9.03 cm), volume of solution consumed (55.61 ml) and protein content in petals (18.21 %) whereas, pulsing with 200ppm 8-HQC +4 per cent sucrose for 24 h resulted in improved bloom appearance and maximum reducing sugar content (418.00mg/g).
