alginate oligosaccharides to enhance drought stress resistance of wheat during growth period

Alginate oligosaccharides (AOS) prepared from degradation of alginate is a potent plant elicitor. Hydroponic experiments were carried out to investigate the mechanism of alginate oligosaccharides (AOS) on improving Triticum aestivum L. resistant ability to drought stress.After alginate oligosaccharides (AOS) application, seedling and root length, fresh weight and relative water content of wheat were increased by 18%, 26%, 43% and 33%. AOS might regulate ABA-dependent signal pathway to enhance drought stress resistance of wheat during growth period.
