The present investigation entitled with “Polyamine effect on biochemical events in sugarcane grown on sodic soils” was carried out to study the efficacy of polyamines viz., putrescine and spermidine to ameliorate the effect of soils sodicity by analysing the lipid peroxidation, chlorophyll a content, chlorophyll b content, total chlorophyll content, reducing sugars, non-reducing sugar, and total sugars. The leaves of the two sugarcane cultivars viz., the salt tolerant CoM 0265 and salt susceptible CoC 671 grown on sodic soils and polyamines were applied at 0, 100 and 500μM concentration. The two foliar application of these polyamines were carried out 45 days after planting with 8 days interval. The leaf samples were collected after 65 days after planting for futher biochemical analysis. The effect of polyamines was comparatively higher in CoM 0265 for lipid peroxidation than the CoC 671. The proline and glycine betaine increased however, sugars were decrease in the sugarcane leaves in both the cultivars when grown in sodic soils. The application of polyamines increased the proline, glycine betaine and sugars content in these two cultivars with increase in concentration of polyamines. Interestingly the proline content was found to be higher in salt susceptible cultivar CoC 671 at 500μM polyamine application than the salt tolerant cultivars CoM 0265.
