By controlling nutritional conditions, temperature, humidity and other factors, cucumber seedlings treated with different concentrations of 5-aminolevulinic acid and agmatine were observed and measured to analyze the changes in their cold resistance. The results showed that 5-aminolevulinic acid and agmatine significantly improved the cold resistance of cucumber seedlings, and the degree of their action was positively correlated with the treatment concentration. This research result has certain theoretical and practical significance for the protection and cold-resistant cultivation of cucumber seedlings, and can provide reference and reference for similar fields of study.【Keywords】5-aminolevulinic acid; Agmatine; Cucumber seedlings; Cold resistance; Impact
