Abstract: 

An investigation was conducted to study the effects of growing media on quality and quantity characteristics of Lilium cut flowers cultivars and their vase life in a factorial experiment based on completely randomized design with three replications. The factors included cultivars in six levels (‘Amarone’, ‘Orlando’, ‘Pink superior’, ‘Pollyanna’, ‘Salsa’, ‘Vignola’), growing media in two levels ( 1/3 coco peat +1/3 perlite +1/3 loam and 1/3 sand +1/3 leaf mold + 1/3 loam) and three different preservative solutions (gibberellic acid, 8- hydroxyquinoline + sucrose and distilled water). The bulbs were planted in two growing media inside the greenhouse. Flowering time. number of flower buds, stem length and chlorophyll content were measured before harvest. All the flowers were picked and pulsed with different preservative solution for 24 hours. Then, cut flowers were transferred to distilled water at temperature of 22°C. Vase life, longevity of leaves, fresh weight and chlorophyll content were measured. Stem length in growing media involve coco peat + perlite was 4.39 cm more than another media. Effects of cultivars were significant on all the characteristics and ‘Salsa’ (mean of 10.25 numbers) has the highest numbers of buds. The cultivar ‘Arnarone’ treated with gibberellic acid showed 43.50% and 55.21 % increase over the control for vase life and longevity of leaves, respectively.
