Based on research data and practical observations, the effect of temperature changes on the characteristics of corn germination was analyzed and the role of JS bioregulator, isolated from Juniperus sabina L. plants and used in increasing corn resistance to abiotic stress was assessed. The studies were conducted on corn hybrids Porumbeni 465 (P465) and Porumbeni 398 (P398) with dent (P465) and flint (P398) grain endosperm in laboratory and field conditions. The modification of root/ seedling length and vigor, as well as metabolic efficiency of corn germination under influence of low (10°C) and high (50°C) temperatures and impact of natural growth regulator JS were also established. Comparison of germination characteristics in laboratory studies with corn emergence in the field and its yield made it possible to establish their correlation relationships, some of which were quite strong (≥0.65). In conclusion, it should be noted that the differences between the studied hybrids in physical structure, chemical
composition of grain and maturity time are reflected in their resilience to temperature stress and response to treatment with a bioregulator.
