IMPACT OF AQUEOUS SULPHUR DIOXIDE ON BIOCHEMICAL PARAMETERS OF RUMEX HESTATA

Abstract

The impact of aqueous SO2 on total chlorophyll, phaeophytin, carotenoids, proteins, amino acids, starch, and free sugars of a perennial herb, Rumex hestata was studied for a period of one year. All these, except free sugars, showed a remarkable decrease, attributed to the over all decrease in enzymatic activities, as compared to that under controlled conditions on exposure to sulphur dioxide. The increase in free sugars is attributed to the fact that hydrolytic enzymes get activated on SO2 treatment and break polysaccharides.
