The changes of the N, P, K, Ca, Mg and Na content in the roots of winter rye and soybean subjected to oxygen stresses for the period of 2 weeks during 3 stages of their development have been examined.
All problems connected with the role of soil oxygen in root growth and functioning are discussed in this review. There are: diffusion of oxygen to and within plant roots, root respiration and factors affecting it, metabolic activity of roots under anoxia, oxygen deficit and root growth and water and nutrient uptake by roots and adaptation of roots to oxygen stress.
