Using salt-sensitive rice variety IR29 and salt-tolerant rice variety FL478 as test materials, a pot experiment was conducted to study the effects of 900mg/L Alginate Oligosaccharide (AOS) on the shoot growth, root morphogenesis, antioxidant enzyme activity, and the effects of 0.3% NaCl stress on rice seedlings. The effects of antioxidant content, osmotic adjustment substance content, malondialdehyde (MDA) content and O2.- production rate.

Effects of foliar spraying of AOS on root establishment of rice seedlings under salt stress
The results showed that spraying exogenous AOS under salt stress could enhance the stress resistance of rice seedling growth under salt stress by enhancing antioxidant and osmotic regulation ability, scavenging excess reactive oxygen species, and reducing membrane lipid peroxidation level. Under the condition of salt stress, foliar spraying of exogenous AOS could promote the root formation of the two rice seedlings, and the promotion effect on IR29 was stronger than that of FL478.
