Proceeding of optimum conditions for the growth of broad bean and spring barley of 22 degrees C and moderate water supply of soil with 55% water capacity, the stomata state advanced with rising temperature and especially with increasing soil moisture. Heat stress as well as surplus water exercised a greater influence on the ultrastructure of the cell than low temperatures and water deficiency. Thus, especially the structures of chloroplasts, mitochondria and ribosomes were affected and damaged, respectively. By deviating from growth optimum, the number of plastoglobuli was increased. The results show that the diminished host suitability to the aphids under extreme stress conditions are caused by the destruction of the internal structure of plant tissue
