DYNAMICS OF K +, NA +, CA2 + IONS IN RICE PLANTS (Oryza sativa L.) IN ONTOGENESIS UNDER SOIL SALINITY

abstract 1001406115 issue 100 pp. 1745 – 1759 30.06.2014 ru 1414
Under conditions of vegetation experiment at soil artificial chloride salinization the dynamics of accumulation and distribution of sodium, potassium and calcium in organs of rice plants (Oryza sativa L.) have been studied, as well as their correlation with tissue hydration in ontogenesis. The significant restriction of salinization ions transport and accumulation, particularly sodium, in the actively functioning upper leaves and panicles has been observed. Whereas the content of calcium and potassium in the experimental and control plants differed slightly

REVISITING THE RICE SALT RESISTANCE (REVIEW)

abstract 1051501057 issue 105 pp. 932 – 947 30.01.2015 ru 838
The total area of saline soils of rice irrigation systems in the Kuban region reaches almost 80 thousands hectares. Salinization and alkalinization here become a limiting factor for cultivating rice and companion crops. In this regard, the tolerance of plants to soil salinity is a current problem of plant breeding that attracts the attention of many agricultural researchers whereas it is necessary to increase the yield in saline soils. Salt tolerance of crop plants is defined by a combination of properties which are based on the specific adaptation mechanisms. These mechanisms differ in nature and are associated with different levels of structural organization of the plant – from molecular to organismic one. The study of adaptation mechanisms at different levels of structural organization of plants is very important for increasing yield in saline soils. This article is a review giving a detailed analysis of plant salt tolerance research, particularly rice, which addresses the issues of inhibition of plant growth under saline conditions, the mechanisms of salt tolerance, the achievements and development of this branch of scientific research, as well as the application results of work found in the scientific literature
