dc.description.abstractThe aim of the study was to determine the effect of hydrothermal conditions, duration of winter and varietal characteristics on the sugar content in tillering nodes and, accordingly, on wintering of м plants in the Right-Bank Forest-Steppe of Ukraine. The direct dependence of the amount of sugars in the tillering nodes of winter wheat (Triticum aestivum L.) on the sum of effective temperatures and the duration of autumn vegetation was established. It was found that under the most favorable conditions prevailing in the autumn growing season of 2019, with the sum of effective temperatures of 984.6 °C and the duration of the autumn growing season of 76 days, the amount of accumulated sugars was 4.7% higher compared to 2016, and was 30.6%. It was found that over the years of research, the sugar content in the tillering nodes of winter wheat (Triticum aestivum L.) was higher in mid-season varieties, but there was no significant difference in varieties within the same maturity group, which confirms the high adaptability of the studied varieties to the soil and climatic conditions of the Right-Bank Forest-Steppe of Ukraine. Favorable climatic conditions in autumn and winter over the years of observation ensured good growth and development of plants in the pre-winter period and contributed to the accumulation of optimal amounts of sugars in tillering nodes, which ensured high winter survival of plants of all winter wheat (Triticum aestivum L.) varieties. The lowest percentage of overwintering was observed in Gorodnitsa variety at 98.8%, and the highest in Astarta variety with an average of 99.8% over the years of research.eng
