Abstract：Taking Corylus maxima Purpurea and Corylus heterophylla Fisch as materials , the change trends of chlorophyll , carotenoid , anthocyanin and soluble sugar in developing leaves were studied in this pa -per.The results indicated that the length and width of leaves increased with the increase of developing days . The leaves developed into functional leaves on about May 27 th.The functional leaves of Corylus heterophylla Fisch were bigger than those of Corylus maxima Purpurea .The contents of anthocyanin , chlorophyll a and b of Corylus maxima Purpurea were higher than those of Corylus heterophylla Fisch, which increased firstly and then decreased during leaf development .The anthocyanin content of Corylus heterophylla Fisch leaves de-creased gradually .The contents of chlorophyll a and b in Corylus heterophylla Fisch leaves increased gradual-ly.The ratio of chlorophyll a/b in Corylus heterophylla Fisch was higher than that of Corylus maxima Pur-purea, and the carotenoid content was contrary .The change trends of soluble sugar in Corylus maxima Pur-purea and Corylus heterophylla Fisch both were up, down, up, down during leaf development , but the time of peak value appeared was different .Correlation analysis indicated that the chlorophyll had very significant posi -tive correlation with anthocyanin in Corylus maxima Purpurea .The chlorophyll of Corylus heterophylla Fisch had significantly positive correlations with carotenoid , and had no significant correlations with the other characters .
