| Abstract | ||
| The study was conducted at the lath house of Hort. Dept./ College of Agric./ University of Baghdad from 1/11/2006 to 15/6/2007. Iris bulbs were planted in the soil of the lath house. Five levels (0, 10, 20, 40, 80 mg/L) of Paclobutrazol were foliar sprayed twice. The first application was when the plants was two months old, the other one was applied one month later. Treated plants were irrigated either by tap water or magnetized water. Paclbutrazol levels reduced plan height, The level 80 mg/L was more effective. While chlorophyll content and dry weight of leaves were increased (533.1 mg/m2 and 34.94 g.) respectively. Irrigating plants by magnetic water elevated, stem diameter, chlorophyll content and leaves dry weight (2.02 cm, 496.8 mg/m2 and 36.73 g.)respectively. Plant growth retardant concentrations were effective on flowering characters as well. Date of flowering was delayed. While flower diameter; length and diameter of the pedicle were increased (10.67 cm, 38.5 cm, 0.98cm. 0.61 g.) respectively. Magnetized water improved all flowering characters. Treated plants produced higher number of bulblets; higher bulblets diameter and higher dry weight (7.87 bulblets/ plant, 3.03 cm and 0.81 g.) respectively. | ||
