Abstract :
ABSTRACT:Soil salinity is a major constraint to food production because it limits crop yield and restricts use of land previously uncultivated.Water and soil management practices have facilitated agricultural production on soils marginalized by salinity but additional gain by these approaches seems problematic.Most crops are salt sensitive or hypersensitive plants (glycophytes) in contrast to halophytes, which are native flora of saline environments. Some halophytes have the capacity to accommodate extreme salinity because of very special anatomical and morphological adaptations or avoidance mechanismsProteins that accumulate in plants under saline conditions may provide a storage form of nitrogen that is re-utilized later and may play a role in osmotic adjustment.Under condition of stress main change will happen in lipids metabolism. Total lipids content in Canola (Brassica napus L.) with increasing NaCl levels was decreased.
