Salinity Stress Tolerance Of Camelina Investigated In Vitro

Salinity Stress and Salt Tolerance

Salinity is one of the most serious factors limiting the productivity of agricultural crops, with adverse effects on germination, plant vigour and crop yield (R Munns & Tester, 2008). Salinization affects many irrigated areas mainly due to the use of brackish water. Worldwide, more than 45 million hectares of irrigated land have been damaged by salt, and 1.5 million hectares are taken out of pr...

Biotechnology of water and salinity stress tolerance.

Drought and salinity are among the environmental factors that constrain agricultural productivity most dramatically. Classical breeding programs aiming to improve stress tolerance have been hampered by the multigenic nature of the trait and the seemingly scarce natural genetic variability in crop plants. Novel genetic determinants governing the function of stomata and improving the performance ...

2 Salinity Stress and Salt Tolerance

Physiology and molecular biology of salinity stress tolerance in plants

The productivity of plants is greatly affected by various environmental stresses. Soil salinity affects plant growth and development by way of osmotic stress, injurious effects of toxic Na and Cl – ions and to some extent Cl – and SO4 2 – of Mg and nutrient imbalance caused by excess of Na and Cl – ions. Salinity stress response is multigenic, as a number of processes involved in the tolerance ...

Evaluation of salinity tolerance in rice genotypes

Salinity is considered as one of important physical factors influencing rice (Oryza sativa L.) production. Knowledge of salinity effects on rice seedling growth and yieldcomponents would improve management practices in fields andincrease our understanding of salt tolerance mechanisms in rice. This study was designed to assess the role of Saltol QTL in regards to effects of salinity on plant gro...
