Accumulation of pigments in wheat leaves under influence of macronutrients

On natural acidic soil, statistically significant relationships between wheat yield and pigment content in leaves were established (for Chl a r = 0.910…0,949; b 0.925…0,967; for carotenoids 2017 0.887;). Nitrogen fertilizer promoted an increase ( - by 38…43%, 16…22%). At phosphorus application, the of chlorophylls increased 44…83%, 20…37%. The mobile arable layer soil is significantly associated with (r 0.738 0.793 2020, respectively) part pigments included light-harvesting complexes 0.799 0.829, respectively). In associations weight ratios / -0.815) + ) 0.840) noted. Soil liming reduced influence on complex leaves: against background, was 27…40%, limed background – 27…29%; contrary, its 93…108%, while only 63…84%. both backgrounds, addition carotenoid (on 7…9%, 17…23%).
