Abstract:
Plants face many biotic and abiotic stresses in natural environment that limits plant growth and productivity. Among the abiotic stresses, salinity and heavy metal toxicity are affecting the plants productivity worldwide. Sesbania rostrata is a small leguminous tree, in the genus Sesbania widely distributed throughout the tropical and subtropical regions and called as the most successful survivors in arid and semi-arid regions as they possessed most of the features required to withstand harsh environmental conditions. The present study was conducted to evaluate the comparative morpho-anatomical response of Sesbania rostrata under different levels of Sodium Chloride and Chromium Oxide. For this purpose, the healthy seeds of Sesbania rostrata were sown in pots filled up with loam soil (2:1) in Central Nursery of the Bagdad-ul -Jadeed Campus. Treatments i.e.100mM NaCl, 200mM NaCl and 300mM NaCl solutions and three different levels of CrO3 i.e.50uM CrO3, 100 uM CrO3 and 150uM CrO3 were given after nearly two weeks of the establishment of the seedling and subsequent treatments were given after one week. Three replicates were kept for each treatment along with control. Sesbania specie showed many structural modifications under salt and heavy metal stresses and showed many specific adaptive characteristics such as number of stomata; epidermal thickness, cortical cell area, cortical thickness and endodermal thickness were increased under both stresses. In conclusion, present study on the Sesbania specie anatomy confirms that the heavy metal had a considerable impact on the development of the adaptive component of Sesbania.
