Dependence of free alanine levels in Festulolium and Trifolium pretense L. on types of N nutrition

Popis výsledku v původním jazyce

This study aims to reveal and to compare effects of two various systems of nitrogen nutrition, namely (1) injection by CULTAN (Controlled Uptake Long Term Ammonium Nutrition) method and (2) conventional application, on free alanine, total N content and visual symptoms in Festulolium and Tripholium pratense L. plants. Calcium nitrate (CN) or ammonium sulphate (AS) were used as N source in the pot experiment. The yield of Festulolium and Tripholium pratense L. above-ground biomass was more substantially enhanced after conventional application of both AS or CN in comparison with CULTAN method. The highest concentration of free alanine was detected in conventional-treated Festulolium with AS and in conventional-treated clover with AS. The contents of N inthe above-ground dry biomass were comparable at all harvesting periods. Visual symptoms suggest that N applied by conventional can maintain better distribution patterns of nutrients and provide improved conditions for growth and N uptake.
