MORPHOLOGICAL CHARACTERIZATION OF TWO CONTRAST RICE GENOTYPES UNDER SALINITY
JAKIA TABASSUM
Abstract
Salinity, among other abiotic stressors, is one of the most devastating constraints to the production of cereal crops, including rice, particularly in coastal areas around the world. To match rising food demand and the expanding trend of saline-affected areas, it is critical to increase rice production in salt-affected areas by enhancing the salinity tolerance of crop cultivars. In this respect, it is imperative to conduct morphological studies under salinity stress conditions to identify saline tolerant variety. In this work, morphological traits of two separate rice genotypes were analyzed under salt conditions. Significant variations were recorded in morphological traits viz., elongation rate of the leaf, shoot, and root, shoot and root length, biomass production. The shoot and root length of the rice plants were reduced significantly by salinity stress. Besides, when comparing the tolerant rice genotype to the susceptible rice genotype, it was found that the tolerant rice genotype produced more biomass. In a nutshell, the findings will facilitate in the understanding and further investigation of numerous growth characteristics in different rice genotypes under conditions of differing salinity levels.
