Four species of AcerA. mandshuricumA. tataricum subsp. ginnala., A. saccharumA. pictum subsp. mono)on Mudanjang were selected as materials in spring, summer and autumn, respectively, and the seasonal variation trend of leaf traits(e.g. leaf thickness(TL), stomata length(LS), stomata width(WS), stomata density(DS), leaf vein density(DV), specific leaf area(ASL) and pigment content) were analyzed, and the relationship between pigments and leaf morphological traits in different seasons were explored respectively. The result showed that: (1)Four kinds of Acer species showed higher TL, lower ASL and DS in summer, higher ASL and DV, lower TL in autumn. (2)The chlorophyll a and b of four Acer species were higher in summer, and the pigment content decreased in autumn. Their seasonal variation ranges were chlorophyll a 77.40%-98.80%, chlorophyll b 85.60%-99.53%, and carotenoids 4.29%-78.52%. (3)Pigment was closely related to leaf morphological traits. Under seasonal dynamics, pigments were positively correlated with ASLDS and DV, and negatively correlated with TLLS and WSP<0.05), but the correlations were slightly different in different seasons. The leaf was formed different construction strategies in response to climatic conditions in different seasons in four color species. The variation of leaf functional traits reflected the trade-off mechanism of colored-leaf plants adapting to seasonal changes.

Key words: seasonal dynamics, morphological traits, pigment, colored-leaf plant, correlation
