• Currently, studies on celery mainly focus on cultivation, genetic breeding, genome discovery, functional genes and chemical composition. Although the beneficial impacts of exogenous proline on plant resilience to abiotic stresses have gained widespread interest, however, there is a lack of research on how exogenous application of proline regulates on mineral nutrition and amino acids, organic acids, and volatile components in celery under salt stress. • In this study, we investigated the potential effects of proline application on mineral nutrients, amino acid fractions, organic acids, nitrate, lignin, dietary fiber and volatile fractions of different parts of celery under salt stress by using the comprehensive evaluation analysis of the affiliation function and correlation analysis. This study aim to provide a theoretical basis for the cultivation of high-quality and high-yielding celery under saline and alkaline soil conditions. Salt stress is one of the constraints limiting high-yield and high-quality cultivation of vegetables, currently, the effect of exogenous proline on the quality of celery under salt stress is rarely reported. The study aimed to explore the comprehensive effects of exogenous proline application on the quality of celery ( Apium graveolens L.) under salt stress. The affiliation function method was used to comprehensively analyze the effects of foliar application of 0.3 mM proline on celery mineral nutrients, amino acids, organic acids, nitrate, dietar...
