Abstract
The study was conducted on spring of 2005 to investigate the influence of different salinity levels of water with / without magnetization on some histological characters of Gerbera jamesonii. Two factors were tested; Salinity levels of irrigation water (0.758 . 1.5 . 2 . 3 . 4 ds/m) the second factor was watering plant with / without magnetized saline water. Split plot in RCBD with three replicates two pot for each replicate was designed. Number of stoma in the lower epidermis of leaves was affected by irrigating plants with saline water, where increased at 1.5 and 4.0 ds/m levels comparing with 0.758, 2 or 3 ds/m the lowest number of stoma was obtained at 3 ds/m level (132.42 stoma/mm2). However . 2 or 3 ds/m levels decreased the number of stoma. Surprisingly the number elevated again at 4 ds/m level (189.67stoma/mm2). Magnetized water increased the water content of petiole. Some parenchyma cells of the petiole were torn especially with the highest level of salinity. Magnetic technology of water reduced the epidermis thickness of petiole.
