| Abstract | ||
| This trial was conducted to investigate the effect of magnetized diluted seawater and bio fertilization on seedlings growth and chemical constituent of Dalbergia sissoo . during the two successive seasons of 2016 /2017 and 2017/2018 at the experimental farm of El-qanater El Khairia Horticultural Research Station, Egypt. Three diluted seawater at concentrations of (2000, 4000 and 5000 mg1-1) as well as control (Nile Water) have taken and four treatments were used namely magnetized diluted seawater alone, biofertilizer with mixtures of Cyanobacteria (algae of Anabaena sp. and Nostoc sp.), biofertilizer plus magnetized technique and the control which non- magnetic and non- biofertilizer. The obtained results demonstrated that different salinity levels significantly reduced increment of seedling height, stem diameter, leaf area, root length and fresh and dry biomass, whereas the high levels of 5000 mg1-1salinity neither the seedlings irrigated with separately saline water nor were treated with magnetization or bio fertilization survived, also salinity caused a reduction in total chlorophylls and total carbohydrates in contrast proline content increased, mineral nutrition's N, P and K % decreased whereas Na increased consequently K+/ Na+ ratio decreased. Treatment of exposure the seedlings to magnetized diluted seawater or non-saline significantly increased all parameters of plant height, stem diameter, leaf area, root length and fresh and dry weight biomass compared to control, also bio fertilization as alone or as a mixture with magnetic device resulted in an increase in total chlorophylls , total carbohydrates in the stem, proline content in leaves and the absorption elements of N, P and K % raised while, Na+ content decreased consequently K+/ Na+ ratio increased. Therefore, the current study cleared that seedlings of Dalbergia sissoo tolerated salinity level up to 4000 mg1-1 and the magnetization or bio fertilization ameliorated most of the growth parameters and enhanced the status of chemical constituents producing healthy seedlings. | ||
