摘要
研究了少花桂幼苗对不同光照条件在形态和生理方面的适应．研究结果表明，随着生境中光照的减弱，植株叶片增大、叶色加浓、光饱和点、光补偿点逐渐下降，Ｃｈｌｂ含量升高，以保持一定的光合速率，适应弱光环境．但过度遮荫导致二氧化碳补偿点提高，固定二氧化碳能力减弱．
he adaptablity of Cinnamommum pauciflorum biennial seedlings to various light intensities in photosynthetic shaped and photosynthetic physiological characteristics is researched.It shows that with the light intensity in which the plants lived weakening,the leaf blades enlarged,the leaf color became thinner,the epidermis hair amount lessened;while the light saturation points and compensation points cut down,chlorophyllb content increased.
