Screening and selection of physio-biochemical traits to detect high temperature tolerance using multivariate analysis in tomato genotypes (Lycopersicon esculentum Mill)

Response of winter wheat genotypes to salinity stress under controlled environments

“…It is well known that soluble sugars play an important role in plant metabolism such as products of hydrolytic TABLE 5 Probability values of effects of salinity (S), genotype (G), and interaction (S x G) on physiological, biochemical, and agronomic traits of selected salinity tolerant (n=4) and suspectable (n=4) winter wheat genotypes at the booting (Feekes 10.0) stage (experiment 2). processes, substrates in biosynthetic processes, and energy production, and act as cellular osmotic regulators (Sunoj et al, 2020;Biradar et al, 2022). Numerous studies have tried to link the increase of soluble sugars to salinity tolerance and the present result agrees with results from wheat genotypes treated with higher salinity level resulted in a significant increase in sugars and proline in some genotypes (Dadkhah and Rassam, 2016;Akbar et al, 2021Akbar et al, , 2022.…”

“…It has been reported that proline plays a protective role in plants exposed to diverse stresses and is thought to be acting as a cellular osmotic regulator. And along with other enzymatic and non-enzymatic ROS quenching mechanisms proline regulates increased ROS production due to the reduced lightdependent and CO 2 assimilation reactions of photosynthesis (Munns and Tester, 2008;Aycan et al, 2022;Singh et al, 2022;Sunoj et al, 2022). A study reported the genotypic differences in proline accumulation under salinity were seen in wheat genotypes (Tavakoli et al, 2016).…”

“…Further, under diverse stress conditions, plants are induced to create changes in several metabolites such as sugars (reducing [glucose and fructose] and non-reducing sugars [sucrose]), starch, protein, and proline (Laxman et al, 2013;Sunoj et al, 2016;Ozturk et al, 2021). Among these metabolites, sugars, protein, and proline are known as osmolytes or osmoprotectants take part in osmotic regulation (Laxman et al, 2013;Ozturk et al, 2021;Biradar et al, 2022). Osmotic tolerance is vital for the plant to survive and maintain its growth rate by preserving optimum photosynthesis at a high salinity level.…”
