| We investigated the effect of salinity on the development of seedlings of Vigna unguiculata. At various time intervals, the hypocotyls were measured to estimate the effect of salt concentration on growth parameters. Control plants were tallest and had the greatest fresh weights, whereas these values were lowest in seedlings treated with high levels of salt. Three hydrogen donors -- caffeic acid, ferulic acid, and pyrogalol -- were studied to determine the changes in peroxidase activity for both cytoplasmic and wall-bound fractions. Activity was inversely correlated with hypocotyl elongation. A dear concentration effect was also observed for contents of pectic polysaccharides, low-molecular-weight xyloglucan, and high-molecular-weight xyloglucan, with control seedlings showing lower levels of those wall components than that recorded in the salt-treated seedlings. Here, we also discuss the role of peroxidase and wall components in hypocotyl elongation and growth of Vigna when seedlings undergo saline stress. |
