EFFECT OF WATER LOGGING ON ROOT AND STEM ANATOMY AND YIELD OF SESAME GENOTYPES (Pages : 18 - 25)

Water logging is an environmental factor that reduces gas exchange between plant tissues and the atmosphere and limits plant growth and yield. A pot experiment was conducted with eight sesame genotypes viz. SM-1, SM-4, SM-7, SM-9, SM-25, SM-26, Krishnotil and Binatil-2 during March to June 2021 to observe the effect of water logging on root and stem anatomy and yield of sesame genotypes. The experiment was laid out in randomized complete block design with three replications. Three waterlogged treatments viz. Control, 48 and 60 hours were imposed at flowering stage of the sesame genotypes. Plant height, capsules plant-1, number of seeds capsule-1, total dry matter plant-1, 1000-seed weight and yield plant-1 were significantly decreased with increasing water logging periods. The highest seed yield was found in SM-26 followed by SM-7 and SM-25. In control root and stem, the orientation of epidermis, hypodermis and vascular bundle were normal. Tissue of root and shoot of sesame genotypes under water logging had a great damage compared to control. Water logging at 60 hrs had more damage of epidermis, hypodermis and vascular bundle compared to 48 hrs. SM-26, SM-7 and SM-25 showed better performance under the treatments.Download
