Abstract
In the conditions of climate change, the existing technologies for winter grain crops growing need constant improvement. Development of the leaf surface and its longest preservation is the main vector of any technology for growing winter wheat, and this issue is especially important in unstable weather conditions. The aim of the research was to establish the influence of multicomponent and multidirectional seed treaters on the state of pigment complex in the leaves of plants of different winter wheat varieties and its productivity during the growing season. When studying pigment complex in the leaves of winter wheat plants in the vegetative period of development this indicator for Antonivka variety was s fund to be 7.17 mg/g of dry matter, and for Shestopalivka variety – 8.04 mg/g of dry matter on average for the variants. The generative period was noted to have an increase in chlorophyll content for both varieties - it was 8.19 mg/g of dry matter for Antonivka and 8.22 mg/g of dry matter for Shestopalivka variety, which is 14.2 % and 2.2 % more than in vegetative period. The productivity of chlorophylls in the vegetative period of plants growth and development averaged 5.14 mg of dry matter/mg of chlorophyll per day for Antonivka, which is 28.4 % more than in Shestopalivka variety (3.69 mg of dry matter/ mg of chlorophyll) per day). With the beginning of the generative period, Shestopalivka variety was noted to have a more stable pigment complex, which is confrmed by a double increase in chlorophylls productivity compared to the previous period. Thus, the increase in chlorophyll content, depending on the pre-sowing treatment with the preparations, is more active in Antonivka variety, but the quantitative index is dominated by Shestopalivka variety. In arid climates, moderate formation of pigments and preservation of their productivity stabilizes grain maturation process, which was noted for both varieties treated with Lamardor and Lamardor plus Gaucho.
Key words: chlorophyll, winter wheat, seed treater, pigment productivity.
