Effect of Moisture Stress on Key Physiological Parameters in Sunflower Genotypes
Journal Title: International Journal of Current Microbiology and Applied Sciences (IJCMAS) - Year 2017, Vol 6, Issue 5
Abstract
A study was conducted to investigate the effect of drought on physiological characteristics in twelve sunflower genotypes. Moisture stress treatment were imposed at flower bud initiation stage (irrigation withheld from 40 DAS to 60 DAS) whereas, Control plots were irrigated at 10 days intervals throughout the crop growth period. Results revealed that water stress showed repressing effect on Relative water content, Photosynthetic rate, leaf fluorescence, membrane leakage, chlorophyll content and specific leaf area in all the genotypes examined. Decline in Specific leaf area under water stress is considered as adaptation to water stress. However, genotypic variation was significant for characters studied. Genotypes SH-177, SH-491 and DSF-111 was considered as promising lines by maintaining higher RWC, photosynthetic rates, leaf fluorescence and SPAD chlorophyll meter readings wither lower membrane leakage and Specific leaf area.
