Popis: Lilies are one of the most important bulbous plants as cut flowers. In the present study, the effect of foliar sprays of different concentrations of benzyladenine (BA) (0.00, 0.25, and 0.50 mM) and salicylic acid (SA) (0.00, 0.10, 0.50, and 1.00 mM) was investigated at four stages of pre-harvest on qualitative and quantitative traits of Lilium ‘Navona’. The studied traits included number of buds, number of leaves, bud length, bud diameter, stem length, stem diameter, leaf length, leaf width, fresh and dry weights of stems and leaves, dry matter of stems and leaves, vase life, peduncle length and diameter, ionic leakage, chlorophyll index, content of anthocyanins, flavonoids, carotenoids and chlorophyll a, chlorophyll b, and total chlorophyll. The highest number of buds and vase life were achieved with 0.50 mM SA and 0.00 mM BA. The highest values for bud diameter and peduncle length were achieved with 1.00 mM SA and 0.00 mM BA, however, there was no significant difference to 0.50 mM SA. In addition, 0.50 mM SA increased stem diameter and length, leaf length and width, and stem fresh weight compared with control. Results showed that increasing BA to 0.50 mM caused undesirable effects on many traits including the number of buds. Since the largest number of buds and the highest vase life were achieved with 0.50 mM SA and 0.00 mM BA and these traits are the most important characters for the quality of Lilium, spraying of 0.50 mM SA is recommended.
