2 ... # #)* $% & '( *-,+ Influence of magnetized saline irrigating Water on vegetative growth of Gerbera jamesonii Sami K.M. Ameen ( 1) and Ali F. Kassim (2) ABSTRACT The study was conducted in lathhouse of Hort. Dept., College of Agric., University of Baghdad during spring season of 2005 to investigate the ability of using magnetized saline water in irrigating Gerbera plant. Two factors were possibility studied; watering plant with saline water (0.758, 1.5, 2, 3, 4 ds/m), and the other factor was the effect of magnetic technology on saline water used in plants irrigation. Split plot according to RCBD with three replicates was designed; each replicate consisted of two pots. High level of saline in irrigating water decreased quality of vegetative characters. Number of leaves; leaves area; chlorophyll percentage, offshoot and fresh and dry weight of leaves of 4 ds/m level were (5.08; cm 2, 25.58%; 1.8; 6.87 g and 1.97 g) respectively. Magnetized saline irrigating water increased leaves content of chlorine (16.35%) comparing with untreated irrigating water. However, leaves content of Ca and Na was decreased (23.13 and 11.09%). The least Cl, Ca, Mg and Na levels in the leaves occurred at ds/m level were (2.415, 2.086, 1.42 and 0.887%) respectively, while S% was 1,015% at the same saline level. Key Words: Gerbera jamesonii, Magnetic technology, Saline irrigating water, Vegetative growth. (1) (2) College of Agric.- Horticulture Department- University of Baghdad.
