Effect of NaCl stress on chlorophyll content of isabgol (Plantagoovata Forsk.) genotypes

摘要

Chlorophyll content in leaves of isabgol [Plantago ovata Forsk.) genotypes viz., GI-2, HI-96, PB-80 and HI-5 was studied under salt stress at different EC levels viz., control (without salt), 5 and 10 d/Sm of nutrient supplemented NaCl salt solutionsin sand filled polythene bags. The results revealed a significant decrease in chlorophyll 'a' and chlorophyll *b' contents with increasing EC levels. Reduction in chlorophyll 'a' and chlorophyll V contents was maximum in the genotype PB-80 and minimum inthe genotype GI-2 indicating the higher tolerance of genotype GI-2 and higher sensitivity of the genotype PB-80 to salt stress among all genotypes studied.
