520 |a The aim of this study was to determine the influence of different heat treatments on the alternative cyanide-resistant oxidase (AOX) capacity and establish a relation between the heat stress tolerance of spring wheat (Triticum aestivum L.), content of water-soluble carbohydrates in leaves and the alternative respiratory pathway (AP) capacity. We identified a positive relation between these studied parameters. Heat exposure at 39 °C for 24 h increased the heat stress tolerance of seedlings, content of water-soluble carbohydrates and AOX capacity, and the AOX capacity was also high after the subsequent influence of heat shock (50 °C for 3 h). The increased AOX capacity correlated with an increased level of water-soluble carbohydrates in leaves. The content of the AOX protein increased after heat exposure at 39 °C (for 3 h and 24 h) and after the subsequent influence of heat shock (50 °C for 1 and 3 h) at 39 °C for 24 h. We also detected that the content of AOX protein isoforms depends on the duration and intensity of heat treatment. It was concluded that AOX plays an important role in the acclimation of plants to high temperatures
