| Abstract | ||
| The present study was conducted in the nursery of Floriculture Unit, University of Baghdad in Iraq during September to December of 2013. Vernalized bulbs of hybrid lily cultivars were imported from the Netherlands. The experiments were included some hybrid lily cultivars which represent the main groups of lily (longiflorum hybrids, Asiatic hybrid and trumpet hybrids). The three lily cultivars named as Tiger (Oriental), Brunello (Asiatic) and White Heaven (Longiflorum) were sprayed two times, at five weeks after planting and at eight weeks after planting with a solution of Cycocel (100 mg /l), solution of Indole butyric acid (50 mg/l) and Benzyl adenine (50 mg /l). The results indicated that foliar spray with IBA lead to increase in plant height, leaf number, leaf area, fresh weight of leaf and stem and dry weight of stem in Brunello. It increased in plant height, leaf area, and fresh and dry weight of stem in White Heaven. Tiger Edition increased in fresh and dry weight of the bulb while decreasing in dry weight by the application of IBA. BA leads to increase in plant height, dry and fresh weight of a leaf, and leaf number in Brunello. It increased in dry weight of a leaf and bulb, and leaf area in Tiger Edition . Also increased in dry weight of stem and bulb, and fresh weight of bulb in White Heaven. While foliar spray with CCC lead to increase in leaf number, leaf area, dry weight of a leaf, dry and fresh weight of stem, and fresh weight of the bulb in Brunello. Dry weight of leaf, and dry and fresh weight of bulb increased in Tiger Edition . Also lead to decrease in fresh weight of a leaf, and increase in fresh and dry weight of bulb in White Heaven. From these results, Brunello was more responsive to PGRs. CCC more PGRs was affected on lily cultivars. | ||
