Abstract
Growth parameters data were used in this study for the evaluation of nine wheat (Triticum aestivum L.) cultivars Giza168, Tabouki, Kaseemi, Yamanei, Madini, Nagrani and Seds 12 at the University of King Abdul Aziz in season 2011. Grains of wheat different cultivars were exposed in batches to weak electric magnetic fields (3000 gauss = 0.3T of magnetic force) for 30 min. Then, the magnetic treated grains were placed in Petri dishes between two layers of moist germination paper by magnetic water. They were placed in the germination incubator at 20 degrees C in an upright position. In order to estimate the rate of germination and percentage of germination. After 21 days, different plant growth parameters were tested such as shoot length, root length, shoot / root length, seedling length, seedling fresh and dry weight based on normal seedlings and effect of magnetic treatments on number of protein bands in wheat seedling. The results showed that all magnetic field treatments increased the rate and percentage of germination, all growth parameters and number of protein bands based on normal seedlings in wheat cultivars. The higher increments observed when grain exposed to weak electric magnetic field strengths 0.3 T at 30 min and dipp in magnetic water compared with control and cultivar Sakha93 showed decreased in the percentage of germination, all seedling growth parameters and numbers of seedling protein bands when exposed to all magnetic field treatments compared with controls, while Masr1 cv. No effected when treated compared with control. Magnetic field and water application gave best results in all seedling parameters compared to unexposed control. [Omar A. Almaghrabi and Esam.K.F.
