附子光合特性研究

Study on the Photosynthetic Characteristics of Aconitum carmichaeli Debx.

以陕西南郑附子两个主要栽培品种老鸦嘴、和尚头及附子野生种为试材,研究附子不同叶位叶片光合速率变化,以及光合速率、光能利用效率和水分利用效率日变化,分析不同品种与野生种及品种间光合特性的差异,对附子栽培措施及当地栽培种的选用进行探讨。

The photosynthetic characteristics of two cultivars and wild Aconitum carmichaeli Debx. were studied. In the paper the change of net photosynthetic rote （Pn） at different leaf nodes and diurnal pattern of net photosynthetic rate （Pn）, light use efficiency and water use efficiency of Aconitum carmichaeli Debx were analyzed.
