Enhancement Wheat Germination and Seedlings Vigor By Using Some Growth Regulators, Antioxidants and Macro And Micronutrients زيادة إنبات القمح و وقوة البادرات باستخدام بعض منظمات النمو ومضادات الأکسدة والعناصر الغذائية

Abstract

To enhancing seedlings parameters of bread wheat Misr 1 cultivar by soaking in ascorbic acid (AsA) as a source of antioxidant, indole-3-acetic acid (IAA) as a source of growth regulator, Truefert powder as a source of macronutrients (NPK) and Folifert powder as a source of micronutrients (Zn, Fe, Mn, Cu, B and Mo), a laboratory experiment was conducted at Agronomy Department Laboratory of Seed Testing, Faculty of Agriculture, Mansoura University, Egypt, during November 2018. The experiment was carried out in completely randomized design (CRD) with four replications. Results showed that treating wheat seeds with solution of ascorbic acid (AsA) + micronutrients at the rates of 0.1 g/l + 3.75 g/l, respectively for 12 hours was the best treatment which produced the maximum values of most seedlings characters, followed by soaking wheat seeds in indole-3-acetic acid (IAA) + micronutrients at the rates of 0.05 g/l+ 3.75g/l, respectively. It could be recommended that soaking wheat seeds Misr 1 cultivar in combination of ascorbic acid (AsA) + Micro (Zn, Fe, Mn, Cu, Mo and B) at the rates of 0.1 g/l+ 3.75g/l, respectively for 12 hours or indole-3-acetic acid (IAA) + micro (Zn, Fe, Mn, Cu, Mo and B) at the rates of 0.05 g/l+ 3.75g/l, respectively for 12 hours to improving germination and seedlings parameters.
