Mikroelementų poveikis vasarinių kviečių vystymuisi organogenezės I –II etapuose

Abstract

Investigations were carried out in 2011–2012 Alexander Stulginskis University (ASU) "Food agronomic inputs and zoo-technical research laboratory. The influence of spring wheat cultivar 'Monsun'. The study used Micronutrients liquid fertilizers with chemical composition: (N – 204; MgO – 27.3; SO3 – 68.2; B – 2.0; Cu – 6.8; Fe – 13.6; Mn – 25.9; Mo – 0.2; Zn – 13.6 g l-1). Vegetative experiment of spring wheat sprayed with water (control variant) and liquid complex fertilizers with organic extracts 0.025 %, 0.05 %, 0.1 % and 0.5 % concentrations. The experiment was conducted in 6 replications. In the experiment used microelement fertilizer from 0.025 to 0.5 % concentrations substantial increase in spring wheat seed root number (0.65 to 3.55 units). Lower concentrations (0.025 and 0.05 %) microelement fertilizer solution slightly increased spring wheat seed root and coleoptile length. For larger concentrations (0.1 and 0.5 %), root length and coleoptile growth compared to the control, suppressed
