摘要: 以6个不同牡丹品种(太平红、玉楼紫、肉芙蓉、金腰楼、彭州紫、凤丹白)为研究对象，对其生物学特性和光合特性进行了比较研究。结果表明：不同品种牡丹均具有较高的观赏价值，生长规律总体一致；玉楼紫株高最高，彭州紫最低，太平红、玉楼紫和彭州紫均为重瓣花。光合特性研究结果表明，金腰楼和玉楼紫净光合速率最高，凤丹白最低；气孔导度和胞间CO2浓度的变化一致，变化顺序为玉楼紫 > 金腰楼 > 彭州紫 > 肉芙蓉 > 太平红 > 丹凤白；玉楼紫和金腰楼以及彭州紫蒸腾速率都较高。
Abstract: The biological and photosynthetic characteristics were comparatively studied in six peony cultivars (Taipinghong, Yulouzi, Roufurong, Jinyaolou, Pengzhouzi, Danfengbai). The results showed that the all peony cultivars possessed high ornamental values and growth regularity was consistent with each other; plant height of Yulouzi peony was the tallest; that of Pengzhouzi peony was opposite. Taipinghong Yulouzi and Pengzhouzi peonies had multiplicate flower. Net photosynthetic rate (Pn) of Jinyaolou and Yulouzi peony was higher than others, and that of Fengdanbai peony was the lowest. The changes of stomata conductance (Gs) and intercellular carbon dioxide concentration (Ci) were uniform, which is Yulouzi > Jinyaolou > Pengzhouzi > Roufurong > Taipinghong > Danfengbai. The transpiration rate (Tr) of Yulouzi Jinyaolou and Pengzhouzi peony was higher than others.
