Abstract:
An attempt was made to study the influence of salinity (100mM, 150mM, 200mM and 250mM NaCl) and alkalinity (50mM, 100mM, 150mM and 200mM NaHCO3) on Plant height, Number of Leaves, Leaf Area, Relative Water Content, Catalase and Peroxidase activity of Andrographis paniculata. Untreated plants were kept as control. The plant samples were analyzed for 100 DAS at every 20 days interval. The results indicated that the reduction in growth parameters were abrupt in Andrographis and decreased in above mentioned growth parameters at high salt concentrations (250mM NaCl and 200mM NaHCO3) were observed. Similarly, alteration in the antioxidant enzymes viz. catalase(CAT) and peroxidase (POD) activity was observed in all the treatment. The maximum increment in CAT and POD activity was recorded at 200mM NaCl and 150mM NaHCO3. The results revealed that the extent of alkaline stress induced changes was higher than saline stress and alkaline conditions impose more deleterious effect on Andrographis plant.
