Effect of biofertilizers and osmotic stress on morphological parameters of spring barley seedlings

One of ways to increase resistance agricultural plants abiotic stresses is the use biofertilizers with anti-stress and growth-regulating properties. They improve absorption nitrogen phosphorus from organic fertilizers soil. The purpose research was study sowing qualities seeds, morphological indicators spring barley seedlings after presowing seed treatment under conditions sufficient humidification osmotic stress. laboratory experiment carried out effect on ( Hordeum vulgare L.) cv. Gubernatorsky insufficient humidification. seeds were treated once according following scheme: 1. control (distilled water) 10 L/t; 2. Gumi 20 M potash (0.4 L/t); 3. Borogum-M complex (0.2 4. PEG 6000 (100 g/L); 5. L/t) + 6. g/L). Treatment increased germination rate capacity by 35 2 %, respectively. When modeling drought using PEG-6000, decreased 4 %. Under humidification, studied had a positive shoot root weight seedlings. In addition, average length roots, shoots total increased. number roots did not change significantly. Lack moisture effectiveness biofertilizer, while potassium biofertilizer parameters water stress conditions.
