To study the effect of vermicompost and humic acid on the vase life and physiological characteristics of the cut flowers of Rosa hybrida cv. Polar star, two separate experiments were carried out. Treatments included five levels of vermicompost (0, 10, 20, 40 and 80 percent) and three levels of humic acid (0, 500 and 1000 mg/ l) which were added to the pots every two weeks. The studied characteristics included vase life, stem length and diameter, flower bud diameter, fresh and dry weight of leaves and stems. Results showed that the longest vase life (11.2 day), highest stem length (61.6 cm) ), stem and diameter (0.64 cm), flower bud diameter (3.11_cm), stem fresh weight (11.8gr), stem dry weight (5.8gr), leaf fresh weight (7.3 gr) and leaf dry weight (3.96 gr) were obtained when 10% of vermicompost was used. There was a negative effect on the mentioned characteristics with increasing the application of vermicompost from 10 to 80%. Flower physiological characteristics improved with increasing the concentrations of humic acid from 0 to 1000 mg/l, but had no effect on vase life. Longest stem length (61.54 cm) and stem diameter (0.64cm), flower bud diameter (2.98cm), stem fresh weight (11.02gr) and dry weight (5.14gr), leaf fresh weight (7.47 gr) and leaf dry weight (3.84 gr) were obtained when 1000 mg/l of Humic acid was used. In conclusion the results showed that morphological characteristics of cut flowers of Polar Star were significantly affected by different treatments of vermicompost and humic acid.
