Effects of Simulated Acid Rain on Germination and Seedling Growth of some Wild and Cultivated Species

S. S. Shaukat and N. Shafiq

Abstract:
The effects of simulated acid rain (SAR) on germination and early seedling growth of five species were studied. Two treatments of SAR were given - pH 3.0 and 4.0 while deionized distilled water served as control. SAR treatment at both the pH decreased the rate as well as the final germination percentage of Clitorea ternatea L. Germination of Senna holosericea (Fresen.) Greuter. and Adenanthera pavonina L remained unaffected by SAR while that of Leucaena leucocephala (Lam.) de Wit. and Senra incana Cav. increased over the controls. Except for Senra incana where root growth was stimulated, SAR markedly inhibited root as well as shoot growth of the test species. The possible causes of differential effects of SAR on plants are discussed.
