Abstract：To investigate the mechanism of the effects of fertilizer application rate on metabolites and differential metabol-ic pathways in cucumber leaves,the cucumber variety Jinyou 30 was used as the test material,and no fertilization(CF0),reduced fertilization(CF0.5),conventional fertilization(CF1),and excessive fertilization(CF2)treatments were set up.Gas chromatography-mass spectrometry(GC-MS)was used to analyze the changes in leaf metabolomics,and the metabol-ic differences between CF0.5,CF2,and CF1 were compared.The results showed that compared with CF1,CF0.5 treat-ment screened 14 differential metabolites,CF2 treatment screened 16 differential metabolites,and CF0.5 and CF2 had a total of 10 differential metabolites.These differential metabolites are mainly divided into amino acids,sugars,and organic acids,and their relative abundance generally shows a downward trend under CF0.5 treatment and an upward trend under CF2 treatment.The changes in differential metabolites may be closely related to nutrient content in soil,and cucumber leaves may respond to fertilization stress by accumulating amino acids and organic acids.
