Kholodny Institute of Botany NASU popup.description2 The effect of high and low positive temperatures on the cells ultrastructural organization of winter wheat (Triticum aestivum L.) seedlings leaves of varieties with contrast tolerance to thermal regime changes (Volodarka and Yatran 60) was investigated. It was shown that specific feature of frost-resistant variety Volodarka is decrease of cross-sectional area and starch grains volume in chloroplasts strome as well as formation of numerous lipid drops in leaves mesofill cells under hypotermia conditions. The influence of high temperature led to the emergence of developed cristae in mitochondria of heat-tolerant variety Yatran 60 leaves, whereas low temperature induced numerous plastoglobules formation in chloroplasts that is the sign of disturbances in lipid metabolism.
