Abstract

Salinity stress decreased plant height, root length, fresh and dry weights of shoot, chlorophyll concentration, as well as K+ concentration as compared to control. While, Na{+} concentration was increased. Low salinity level 1500 ppm (4.84 dSm{-1}) increased plant height and chlorophyll a concentration. High reduction in this parameters occurred under high salinity level 6000 ppm NaCl (11.88 dSm{-1}). Pre-soaking of sweet pepper seeds in either glycinebetaine or ascorbic acid partially counteracted the harmful effect of NaCl salinity. Low salinity level increased thickness of either midrib region or leaf blade (palisade and spongy parenchyma) as well as the main vascular bundle dimensions. Whereas, moderate and high salinity levels led to a decrease in these parameters. Pre-treatment with glycinebetaine or ascorbic acid mitigated the affect of salinity on thickness of the midrib region and mesophyll tissue of leaf blade. However, all studied anatomical characters were increased as compared to untreated plants grown under such salinity levels.
