摘　　要：为探明油茶发育过程中叶片生理生化指标变化与环境的关系,以普通油茶长林4号叶片为研究对象,分析叶片生理生化指标变化,结果表明:油茶叶片碳氮化合物和内源激素含量在不同月份间变化差异极显著;叶片中可溶性蛋白含量在12月份最低,仅为5.84%,翌年4月份最高,为10.17%;可溶性总糖含量春梢萌发初期较低,为5.85%,在花盛开期(11月份)达到最高,为13.39%;蔗糖含量以翌年1月份最高,达到7.42%,翌年4月份最低,为0.23%;果糖含量在翌年2月份最高,为4.90%,翌年4月份最低,为0.57%;油茶叶片中生长素含量4月份最高,达到了171.19 ng·g FW^(-1),翌年5月份最低,为35.73 ng·g FW^(-1);赤霉素含量4月份最高,为23.92 ng·g FW^(-1),12月份最低,为5.01 ng·g FW^(-1);玉米素含量5月份最高,达到19.82 ng·g FW^(-1),翌年5月份最低,仅为9.32 ng·g FW^(-1);脱落酸含量在4月份最高,为225.49 ng·g FW^(-1),翌年4月份最低,为125.71 ng·g FW^(-1)。In order to study the relationship physiological and biochemical with the environment, leaves of Chang Lin 4#were used as the research materials, then analysis changes of leaf physiological and biochemical, the results showed that： carbon and nitrogen compounds and plant endogenous hormones content had significantly different changed each month between; the soluble protein content in December was the lowest（5.84%） and highest（10.17%） in next April, soluble sugar content was low（5.85%）germination early,and reached the highest（13.39%） in bloom period（November）, sucrose content was the lowest content（0.23%） in May and highest（7.42%） in next January, fructose was the highest（4.90%） in next February and lowest content（0.57%）in next April; The IAA content was the highest（171.19 ng·g FW-1） in April and lowest（35.73 ng·g FW-1） in next May, the GA content was the highest（23.92 ng·g FW-1）in April and lowest（5.01 ng·g FW-1）in December, the ZR content was the highest（19.82 ng·g FW-1）in May and lowest（9.32 ng·g FW-1） in next May, the ABA content was the highest（225.49 ng·g FW-1）in April and lowest（125.71 ng·g FW-1）in next April.
