The present work provides results of a number of biotechnological studies aimed at creating cell lines and entire plants resistant to anaerobic stress. Developed biotechnological approaches were based on earlier fundamental researches into anaerobic stress in plants, so Introduction briefly covers the importance of the problem and focuses on works considering two main strategies of plants adaptation to anaerobic stress. Those are adaptation at molecular level where key factor is anaerobic metabolism of energy (true tolerance) and adaptation of the entire plant via formation of aerenchyma and facilitated transportation of oxygen (apparent tolerance). Thus, sugarcane and wheat cells resistant to anaerobic stress were obtained through consecutive in vitro selection under conditions of anoxia and absence of exogenous carbohydrates. Tolerant wheat cells were used to regenerate entire plants of higher resistance to root anaerobiosis. It has been demonstrated that cells tolerance to anoxia is significantly supported by their ability to utilize exogenous nitrate. Cells tolerance established itself at the genetic level and was inherited by further generations. Apart from that, other successful attempts to increase tolerance of plants to anaerobic stress by means of stimulation of glycolysis and overexpression of genes responsible for cytokinin synthesis and programmed cell death are also discussed. The presented data proved the notion of two main strategies of plants adaptation to anaerobic stress proposed earlier on the base of fundamental studies.

In vitro selection using of salt (NaCl) has been used to select plants that tolerate salinity, so that effective selection process. The purpose of this study was to obtain information about the mechanism of salinity tolerance in rice in vitro conditions. This study consisted of two experiments, they are the selection of salinity tolerance somaclone putative mutants in vitro and study of salinity tolerance mechanism results in in vitro selection. The tolerant plants after being treated NaCl show response to the accumulation of proline is more, the content of K, Mg and Ca which tends to remain and Na content is lower, stomata density is fewer and the length and width ratio stomata is greater.
