Abstract

Five separate experiments were conducted during the two years of 2002 and 2003 to investigate the effect of some soaking treatments on the germination of pepper seeds in addition to study the effect of magnetic field and some levels of salinity on the germination characteristics, seedling growth characteristics, mineral and pigment content of the resulted seedlings. These experiments were conducted with locally-produced seeds of pepper (c.v California Wonder) at the Agriculture Research Centre of Egypt. In the micronutrient experiment, seeds of pepper were soaked in 4 micronutrients (CuSO4 at 50, 100 and 150 ppm), (ZnSO4 at 150, 200 and 250 ppm), (MnSO4 at 150,300 and 350 ppm) and boric acid (75 and 150 ppm) plus the control treatment (soaking in distilled water only) for 24 hours at room temperature (26-30°C) then germinated on moistened filter paper in Petri dishes to the end of the germination period. Seeds were irrigated with distilled water only as it requires. In the macronutrients experiment, pepper seeds were soaked in potassium nitrate (at 0.1, 0.2 and 0.3%) and potassium phosphate (at 0.2, 0.3 and 0.4%) plus the control treatment (soaking in distilled water only) for 24 hours at room temperature (26-30°C) then germinated on moistened filter paper in Petri dishes to the end of the germination period. Seeds were irrigated with distilled water only as it requires. In the growth regulators experiment, pepper seeds were soaked in gibberellin (at 30, 60 and 90 ppm) and kinetin (at 0.2, 0.4 and 0.8 ppm) plus the control treatment (soaking in distilled water) for 24 hours at room temperature (26-30°C) then germinated on moistened filter paper in Petri dishes to the end of the germination period. In salinity experiment seeds were irrigated with distilled water only as it requires in the control treatment (without NaCI) and with brackish water (with NaCI) in the other treatments at 2, 4, 6, 8 and 10 dS/m. In the magnetic field experiment, pepper seeds were soaked for 24 hours in magnetic distilled water at room temperature (26-30°C) plus the control treatment (soaking in distilled water) then germinated on moistened filter paper in Petri dishes. Five pieces of Gauss-Ban (a flat and oval shape of rust-free ferrite magnet therapeutic device, magnetized with over 700 gauss of magnetism) were put under the dishes after sowing till the end of the germination period. Seeds were irrigated with distilled water as it requires. Data recorded were: Germination characteristics, were determined in terms of germination percentage, coefficient of velocity and germination rate. - Seedling growth characteristics, were evaluated in terms length, dry and fresh weight. - Chemical content, in terms of mineral content and pigment content In cotyledon leaves was recorded.
