Preharvest application of citric acid is a novel method in vase life extension of Cut flowers which is reported on tuberose earlier and confirmed here on lilium. In this research three levels of Citric acid (0, 0.075, 0.15 percent v/v) and malic acid (0, 0.075, 0.15 percent v/v) were used together two times during growth period of lilium plants in a randomized factorial design with three replications. The results indicate that 0.15% citric acid had increased vaselife from 13.1 to 14 days (α=0.05). The interesting finding was the effect of citric acid on bulbil weight which had increased from 3.5 gr to 8.5 g in 0.15% citric acid (α=0.05). Malic acid while having no effect on pre-mentioned traits, surprisingly increased the chlorophyll content significantly. The interaction effect between citric acid and malic acid on vase life and chlorophyll content proved significant and was evident in results both as antagonistic and synergistic in various traits. In ANOVA analysis the effect of citric acid on vase-life extension was more prominent increasing it from 11.8 to 14.3 days in treatment with 0.15% citric acid and without malic acid comparing to control. Some assumptions about the possible physiological background are made.
