Abstract/Contents:"The effects of saline sodic stress on growth and physiological response of perennial ryegrass (Lolium perenne) were investigated in a greenhouse hydroponics experiment. Relative transpiration rate, shoot height, root length, water content, chlorophyll content, malondiadehyde [malondialdehyde] (MDA) content were measured together with the activities of superoxide dismutase (SOD), catalase (CAT), peroxidase (POD) of perennial ryegrass seedlings treated with one of five pH levels [6.5 (The control), 8.2, 9.1, 9.9, and 10.9 mixture of 0.1 mol/L Na2CO3, NaHCO3] and distilled water. As pH values increased, relative transpiration rate, shoot height, root length, water content, and chlorophyll content were significantly reduced compared with the control, while the ratio of root to shoot initially increased but then decreased. MDA contents increased (from 7.0 nmol/g FW to 30.0 nmol/g FW) with an increase of pH. At pH=9.1, SOD activity was the highest (8.4 U/mg protein). CAT activity was highest (118.5 U/min·g protein) at pH=6.5 and then declined at higher pH values. POD was lowest at pH=6.5 but increased as pH values increased."
