Investigation some morphophysilological traits of parsley (Petroselinum hortense) ‎under deficit irrigation and salinity stress in greenhouse conditions

In order to investigate amount of deficit irrigation and different levels of water salinity on some morphophysiological traits of parsley, an factorial experiment based on completely block design in three replicates was carried in greenhouse condition. The first factor include irrigation amount at three levels (60, 80 and 100% of field capacity) and the second factor include water salinity at three levels (0.5, 2 and 4 dS/m). Results showed that decreasing irrigation and increasing water salinity cause deacreasing plant height, leaf number per plant, aerial fresh and dry weight, root fresh and dry weight, relative water content and chlorophile content. With increasing salinity to 4 dS/m ion leakage and activity of catalase and ascorbate peroxidase increased and with increasing amount of irrigation these traits reduced significantly.
