dc.description.abstractCadmium is a highly toxic metallic pollutant which adversely affects plant growth. A green house experiment was conducted to study the variation in growth, yield and proline content of four chickpea (Cicer arietinum L.) cultivars namely ICC1069, ICC12422, ICC7589 and ICC4969 at two plant growth stages (30 and 60 days after sowing), treated with 0, 25, 50 and 100 mg Cd kg-1 soil. Plant growth, plant fresh weight, plant biomass, leaf area, total photosynthetic area, carbonic anhydrase activity, yield and proline content exhibited a dose- dependent response to Cd on four cultivars of Cicer arietinum L. The shoot and root length showed a reduction of 10.02, 10.63, 12.97, 7.93 and 4.95, 6.09, 7.85, 9.23% in all the four cultivars respectively, whereas shoot and root dry weight showed a reduction of 18.82, 27.61, 11.27, 44.59 and 10.63, 4.89, 3, 11.94% in all the cultivars respectively at 50 mg Cd kg-1 soil at 30 days of growth stage. It was a general observation from the results that all the parameters of plants were reduced in a concentration-duration dependent manner. However, the proline content of leaf is increased with the increase in Cd concentration. It showed an increase of 15.66, 17.5, 18.42 and 23.61% at 100 mg Cd kg-1 soil at 30 days of growth stage. Maximal significant reductions in the growth characteristics were observed with 100 mg Cd kg-1 soil in all the cultivars in both the samplings. Among cultivars, ICC1069 proved tolerant and showed lesser decrease in the growth characteristics, whereas ICC4969 proved as non-tolerant and showed maximum decrease in the growth characteristics.en_US
