Background and Objective: Salinity is abiotic stress that affects rice growth and results in lower yields. This research studied the effects of salinity on Tubtim Chumphae rice growth. Materials and Methods: Seedlings were cultivated for 35 days in the soil before being stressed by salinity (0, 25, 50, 75 and 100 mM NaCl) for 4 weeks. Growth performance and some physiological traits were recorded weekly for 4 weeks. Results: Under salinity stress, fresh and dry weight of shoot and root, relative dry weight, plant length and root length all decreased as salt solution concentration increased. Electrolyte leakage percentage and malondialdehyde content increased when rice was exposed to the salt solution for 4 weeks, indicating that high salinity damaged the lipid membrane. The PCA results revealed positive correlations among growth parameters that negatively correlated with MDA content and electrolyte leakage. The HCA results confirmed the PCA biplot showing decreasing expression of growth parameters with rising salt stress levels, while MDA content and electrolyte leakage continuously increased. Results suggested MDA content and electrolyte leakage as indicators for salt stress in Tubtim Chumphae rice at seedling and early vegetative stage. Conclusion: Findings in this study indicated that Tubtim Chumphae rice plants can grow in slight to moderate salinity soil. Results will deliver advantageous data that can be integrated with additional agronomical characters in rice growth or breeding plans for abiotic stress-tolerant cultivars improvement.

“…This combined stress is a major limiting factor for rice cultivation and productivity ( Landi et al., 2017 ), triggering oxidative, osmotic, and temperature stresses leading to cellular dehydration and reduced cytosolic and vacuolar volume ( Fan et al., 2015 ). ROS production under combined salinity and drought stress amplifies the damage to proteins, DNA, and membranes ( Landi et al., 2017 ), reducing the photosynthetic rate and efficiency and inducing programmed cell death; thus reducing yields by more than 30% each year ( Bhar, 2020 ).…”

Abiotic stresses adversely affect rice yield and productivity, especially under the changing climatic scenario. Exposure to multiple abiotic stresses acting together aggravates these effects. The projected increase in global temperatures, rainfall variability, and salinity will increase the frequency and intensity of multiple abiotic stresses. These abiotic stresses affect paddy physiology and deteriorate grain quality, especially milling quality and cooking characteristics. Understanding the molecular and physiological mechanisms behind grain quality reduction under multiple abiotic stresses is needed to breed cultivars that can tolerate multiple abiotic stresses. This review summarizes the combined effect of various stresses on rice physiology, focusing on grain quality parameters and yield traits, and discusses strategies for improving grain quality parameters using high-throughput phenotyping with omics approaches.
