A comparative assessment of transpiration, root growth, and hydraulic conductivity in wheat plants varieties Bashkirskaya 28 and Omskaya 35was performed under laboratory conditions. Plants of the Bashkirskaya variety were characterized by increased transpiration and hydraulic conductivity under both stress and normal conditions, and the Omskaya 35 variety was characterized by the ability to save water. Comparison of plant productivity over the past 5 years revealed its higher level in plants of the variety Bashkirskaya 28. Hydrothermal coefficient has been below1.0 over the years, indicating that reduced water availability, and a higher yield of plants of the Bashkirskaya 28 variety indicates that the ability to maintain water flow is more important than to save it in these climatic conditions.
