THE EFFECT OF BACILLUS BACTERIAL STRAINS ON CHLOROPHYLL CONTENT AT DIFFERENT PHENOLOGICAL STAGES OF REGENERATIVE WHEAT
This article presents data on the effect of chemical preparations and bacterial strains on the amount of photosynthetic pigments
(chlorophylls and carotenoids) at different growth phases of winter wheat. The cultivars Asr and Zimnitsa of winter wheat were
taken as research objects. As a result, it was found that the content of chlorophyll Chl “a” in winter wheat was 1.383 mg/g, Chl “b”
– 0.903 mg/g, and carotenoids – 0.405 mg/g. It was revealed that the amount of chlorophyll Chl “a” varied across developmental
phases. During the flowering phase, compared to the accumulation phase, the amount of chlorophyll Chl “a” increased from 0.979
mg/g to 2.35 mg/g. In the variant treated with bacterial strains (Bacillus megaterium, B. subtilis, B. licheniformis), the content of
Chl “a” increased by 0.4 mg/g compared to the control. The use of solutions prepared from Bacillus strains is recommended for
regenerative crop production.
