Accumulation of plastid pigments in the leaves Triticum avestium L. under influence of composite recultivant Trevitan®
Abstract
Aim. To investigate the efficiency of using composite recultivants TREVITAN® (RCT) according to the parameters of accumulation of the photosynthetic pigments in the leaves Triticum aestivum L. of the varieties Quintus and Licamero. Methods. The experiments were carried out on the plots of the agro-biolaboratory of Ternopil Volodymyr Hnatyuk National Pedagogical University in 4 variants (Control, TREVITAN® adjuvant, recultivants TREVITAN®, TREVITAN® adjuvant + recultivants TREVITAN®) and 3 repetitions. The content of chlorophylls a, b and carotenoids in flag leaves was defined by Welburn spectrometric method. Results. The highest content of chlorophylls was found in the leaves of both varieties of wheat in the phases of flowering and milk ripeness during autumn tillage, seeds before sowing and plants in the earing phase with recultivants TREVITAN®. Joint use of TREVITAN® adjuvant + recultivants TREVITAN® also significantly increased the content of chlorophyll in wheat leaves. Increase of carotenoids in the leaves of plants of all experimental variants on 4.2–14.6 % (variety Quintus) and on 43.2–59.5 % (variety Licamero) was defined in the phase of milk ripeness. Conclusions. The use of RCT in the technology of growing soft wheat had a significant impact on the accumulation of photosynthetic pigments in leaves during the generative phases of development.
