Morpho-physiological Analysis of Salinity Tolerance in Sugarcane Genotypes

The productivity of important crops, particularly sugarcane, is greatly impacted by increased crop vulnerability to changing climatic conditions, including various abiotic stress factors like temperature, waterlogging, drought, etc. Salinity tolerance potential of five high yielding sugarcane genotypes was determined based on morpho-physiological, biochemical, and yield traits. The findings showed that morphological features (plant height, leaf area, stem diameter, number of internodes, and internodal length) were suppressed under salinity stress (ECiw 4, 8 and 10 dS/m). The relative water content (RWC) decreased by 4.4–12.5
