Abstract
Aim. To study of the duration life cycle and phenological phases of plants of Nigella sativa L. (variability depending on height above sea level, seed quality and climatic conditions of the year).
Material and Methods. Generally accepted methods described in the relevant guidelines were used in conducting the research. Samples of Nigella sativa (black cumin) were sourced from various eco‐geographical origins: Saudi Arabia, Ethiopia, Syria, Egypt and Azerbaijan.
Results. It was determined that with an increase in height above sea level of the place of growth, the life cycle of plants of N. sativa samples is prolonged and their content of palmitic acid decreases.
Conclusion. The main reason for the above‐mentioned negative changes is a decrease in the average daily temperature with altitude above sea level and, as a result, a delay in the accumulation of the sum of effective temperatures necessary for the passage of certain stages of individual development and the life cycle as a whole.
