A Note on the Anatomical Changes Induced by High Salinity Water in Leaves of Vetiver (Chrysopogon zizanioides (L.) Roberty

Ahmed Dafalla Zein Alabdeen, Eltayeb Elhag Ali Ahmed


Vetiver (Chrysopogon zizanioides (L.) Roberty), a hedge-forming grass with high tolerance to salinity, was grown in pots in a sandy soil "from root divisions", to investigate the effect of salinity on the growth of vetiver. Four levels of Red Sea water mixed with fresh water were used in the following ratios of sea water to fresh water: 0:1 (EC, 0.4 dSm-1) as a control, 1:20 (EC, 3.1 dSm-1), 1:10 (EC, 5.5 dSm-1) and 1:5 (EC, 9.3 dSm-1). Extensive salinity- induced modifications in the form of large air spaces resulting from the destruction of parenchymatous cells were observed in the mesophyll. Photosynthetic tissue was reduced appreciably and closely packed around vascular bundles and the epidermis was also extensively suberized
