In an experiment, cut flowers of rose cv. First Red with uniform length of 45 cm, harvested in October 2003 and 2004 were pulsed in 200 ppm 8-HQC + 3 per cent sucrose and stored at 2°C for five durations i.e., 0, 3, 6, 9 or 12 d in three storage solutions viz., 50 ppm 8-HQC +1.5 per cent sucrose, 200 ppm 8-HQC + 3 per cent sucrose, and chlorinated water and were stored. The results showed that the maximum flower diameter (8.50cm), vase life (19.28 d), volume of solution consumed (53.31ml) and proteins (17.87%) were observed when cut spikes were stored for zero day in 50 ppm 8-HQC +1.5 per cent sucrose, 200 ppm 8-HQC + 3 per cent sucrose and chlorinated water (W0S1, W0S2, W0S3) followed by three day storage in 50 ppm 8-HQC +1.5 per cent sucrose and chlorinated water (W1S1, W1S3). However, maximum reducing sugars content (445.50 mg/g) was recorded in flowers stored for 9 day in 50 ppm 8-HQC +1.5 per cent sucrose (W3S1).
