Chickpea, a nutritionally rich annual legume predominantly cultivated in drought-prone regions, relies on photosynthesis for biomass production and grain formation. The resilience of this process is crucial for productivity under water stress, which induces leaf desiccation. In this study, 15 Cicer accessions from various species were assessed for deficit moisture stress tolerance based on photosystem-II (PS-II) efficiency during 30 h of gradual leaf moisture loss. A significant 33.26% reduction in the maximum quantum efficiency of PS-II was noted as absolute leaf moisture content (ALMC) decreased by 67.79%. Chlorophyll fluorescence-based imaging tools, known for their efficacy in screening genotypes for drought tolerance, revealed PS-II tolerance to tissue dehydration as a reliable indicator. Notably, Cicer accessions viz., WC-02 (ICC17126), WC-08 (ICC17141), and CH-05 (ICC2580) exhibited higher tolerance, evident through elevated ALMC, increased proline content, and sustained PS-II efficiency. The optimized method demonstrated in this study holds promise for assessing Cicer accessions' deficit moisture stress tolerance. [ABSTRACT FROM AUTHOR] |
