Structure and the maintenance of pigments of photosynthesis in leaves of sprouts of winter soft wheat

The results of the estimation of photosynthetic pigments of some varieties of winter soft wheat of Saratov breeding are presented in the article. The research was carried out on the basis of the Laboratory of Selection and Seed Growing of Winter Wheat of the Federal State Budget Scientific Institution “Scientific Research Institute of Agriculture of the South-East”. The peculiarities in the content of pigments of different groups (chlorophylls a and b, carotenoids) are revealed, as well as the relationships between them in the leaves of wheat. In the course of the study, differences were found in the test parameter between varieties of different types of winter soft wheat (lutescens, gosteonum) and between varieties of the same species (lutescens). Varieties with high potential photochemical activity were determined. All studied varieties of Saratov breeding have a high degree of resistance to unfavorable factors.
