Abstract
Soil salinity is a major abiotic stress that seriously impairs crop growth and development, limiting global food production. As a primary staple food, wheat reduced grain yield and quality under salt stress, posing significant challenges to food security. Recent studies indicate that choline chloride, a safe and efficient plant growth regulator, can alleviate drought symptoms in wheat seedling and enhance crop salt tolerance.In this study, the growth and physiological indexes of wheat seedlings were determined by hydroponics.The current study demonstrates that application of 400 mg.L-1 choline chloride effectively mitigates salt stress symptoms in wheat seedlings. Specifically, it increases leaf chlorophyll content while reducing osmic and oxidative stress biomarkers. Furthermore, choline chloride treatment significantly boosts the activity of key reactive oxygen species (ROS)-scavenging enzymes. These findings hold considerable promise for famers cultivating saline soils.
期刊介绍:
In an ever changing world, plant science is of the utmost importance for securing the future well-being of humankind. Plants provide oxygen, food, feed, fibers, and building materials. In addition, they are a diverse source of industrial and pharmaceutical chemicals. Plants are centrally important to the health of ecosystems, and their understanding is critical for learning how to manage and maintain a sustainable biosphere. Plant science is extremely interdisciplinary, reaching from agricultural science to paleobotany, and molecular physiology to ecology. It uses the latest developments in computer science, optics, molecular biology and genomics to address challenges in model systems, agricultural crops, and ecosystems. Plant science research inquires into the form, function, development, diversity, reproduction, evolution and uses of both higher and lower plants and their interactions with other organisms throughout the biosphere. Frontiers in Plant Science welcomes outstanding contributions in any field of plant science from basic to applied research, from organismal to molecular studies, from single plant analysis to studies of populations and whole ecosystems, and from molecular to biophysical to computational approaches.
Frontiers in Plant Science publishes articles on the most outstanding discoveries across a wide research spectrum of Plant Science. The mission of Frontiers in Plant Science is to bring all relevant Plant Science areas together on a single platform.
