Alleviation of salt stress in Glycyrrhiza uralensis by lanthanum nitrate: a predictive modeling approach
Year: 2025
Type: article
Abstract: Seedling growth of Glycyrrhiza uralensis is severely inhibited by salt stress, limiting its cultivation in saline-alkali soils. This study aimed to evaluate the mitigative effects of lanthanum nitrate (La(NO 3 ) 3 ) and develop a predictive model for the salt stress response. The results showed that the photosynthesis, anti-oxidative stress, growth and relative content of pharmacological active components of G.uralensis were significantly inhibited under salt stress. Under 0.75 mM exogenous La(NO 3 ) 3 treatment, licorice under salt stress showed photosynthetic compensation recovery, activation of antioxidant defense, synergistic improvement of biomass and medicinal quality. At the same time, this study innovatively constructs the NRBO-LSSVM-ABKDE coupling prediction model, and its prediction accuracy is significantly better than the traditional algorithm, and the mitigation effect of La(NO 3 ) 3 on G.uralensis was successfully verified. These findings not only confirm the efficacy of La(NO 3 ) 3 in alleviating salt stress in G. uralensis but also provide a powerful predictive tool for assessing plant stress responses, offering a new strategy for sustainable agriculture in salt-affected areas.
