The response of plants to low temperatures has been determined in cereals differing in tolerance to environmental acidity, aluminum ions, and drought in the seedling stage. An interrelation is found between acid, drought, and cold tolerance in spring wheat and barley. It is shown that cold tolerance can be a dynamic indicator of one of the types of stress.
The effect of acidity of the medium, aluminum ions, and low temperatures on tolerance of plants to stresses is studied on seedlings of various cereal crops. It is shown that acid-and aluminum-tolerant spring and winter wheat and rye cultivars have tolerance to frosts and freezing. The degree of tolerance of the cultivar can be diagnosed from the reaction of(More)
The reaction of spring wheat varieties during advance of soil drought is studied. Disparity of the critical period of ontogeny is shown and it is established that depression of variety productivity depends on the degree of rudimentary spike development upon reaching the permanent wilting point of the plants.
Under conditions of a pot experiment, the authors assessed the effect of various environmental conditions: three levels of nitrogen nutrition and temperature and light conditions on assimilation of nitrates in wheat plants differing in stem height. It is found that the need for nitrates in short-stemmed varieties is lower than in tall varieties under(More)
