Abstract
The influence of high temperatures on sunflower chlorophyll mutants was studied. The tolerance criteria were the level of chromosome aberrations and the mitotic index in the root apical meristem of seedlings, the level of nucleus-free cells in the epidermis of cotyledonous leaves, and the intensity of chlorophyll accumulation after the action of heat shock (HS). In addition, the frequency of plants with an altered content of pigments in M1 and M2 was analyzed. The results indicated that the plastomic mutant en-chlorina-5 is more tolerant to temperature stress as compared to other sunflower lines.
