Rezumat

Maize (Zea mays L.) a strategic cereal crop, ranks third in the world in terms of sown area, after wheat and rice. Maize products are utilized in a range of branches, including feed, food and processing industry, medicine etc. In recent years, humanity has been facing the effects of climate change on the planet and the unpredictable climatological anomalies related to it. Among extreme climatic factors, the thermal stresses conditions had a serious impact on the growth, development and productivity of maize. NASA study results show that climate change could affect corn pro-duction as early as 2030, which is expected to fall by 24% [1]. In this regard, the use of various methods to increase plant resistance to heat stress is one of the most important tasks for both agriculture and scientific researches. One of the ways that are widespread in terms of increasing resistance to stress factors is the preliminary processing of seeds with natural growth regulators, to activate the initial stages of germination, growth rate and formation of a powerful root system that could subsequently affect favorably the whole course of plants ontogenesis. The purpose of the study consisted in studying the influence of preliminary processing maize seeds with bioregulator Reglalg on germination and growth parameters of seedlings, depending on the action of high temperatures.
