tailieunhanh - Effect of terminal heat stress on variability in physiological traits of indian mustard (Brassica juncea L.) due to late sown situation

The investigation entitled “Effect of terminal heat stress on variability in physiological traits of Indian mustard (Brassica juncea L.) due to late sown situation” was conductedrabi season during 2017-18 and 2018-19 at Oil seed research Farm Kalyanpur of C. S. Azad University of Agriculture and Technology, Kanpur (.) in randomized block design with three replications and twelve Indian mustard genotype. Physiological parameters ., Chlorophyll Content was recorded at anthesis and siliquae initiation stage; Chlorophyll Stability Index (CSI %), Net Photosynthesis Rate [(Pn) (µ mol/m-2 /s1 )],Relative Water Content (RWC %)and Canopy Temperature Depression (CTD 0C) were estimated at pre-flowering and post-flowering revealed that DRMRIJ16-3, RGN-403 and RH-1556 recorded higher CSI (, and ), net photosynthesis rate (, and ), Relative Water Content (, and ) and canopy temperature depression (, and ) at post-flowering stage, while higher chlorophyll content was recorded (, and ) at siliquae initiation stage. The study indicated that mustard genotypesDRMRIJ16-3, RGN-403 and RH-1556 had tolerance to high temperature stress with delayed sowing, as they maintained higher values of these physiological parameters. | Effect of terminal heat stress on variability in physiological traits of indian mustard (Brassica juncea L.) due to late sown situation
