Abstract
The influence of ascorbic and salicylic acids in alleviating the adverse effects of soil salinity on growth and chemical composition of Khaya senegalensis seedlings was investigated.
Soil salinity, especially at the high level (0.7%) decreased different vegetative growth characters, namely, plant height, stem diameter , number of leaves and dry weight of leaves, stem and roots , as well as, chlorophyll a & b, carotenoids and leaves % of N, P and K. While, leaves % of Na, Ca and proline were increased due to salinity treatments. On the other side, ascorbic acid and salicylic acid, particularly, at the high concentration (200 ppm) each, improved all prementioned vegetative growth traits and leaves content of the three photosynthetic pigments and N, P and K %, meanwhile, leaves % of Na, Ca and proline were reduced. Both ascorbic acid and salicylic acid were effective in alleviating the harmful effects of salinity on growth and chemical constituents of Khaya senegalensis seedlings.
