GANESH IYER AND SEEMA MENON
Abstract
Experiments were conducted in order to characterize the injuries on leaves and evaluate the degree of susceptibility of Pedilanthus tithymeloides Linn. to stimulated acid rain(SAR). Plants Were treated for one month for different pH like 4.54, 5.6,and 6.55. Control plants were stimulated with distilled water.Transverse section of leaves were taken to observe the effect on cuticle, epidermis and mesophyll tissue. Effect on chloroplast density and shape were also noted. Recovery period after the treatment were studied. Leaves recovered within 15 days.
