采用LI-6400XT便携式光合测定系统, 研究了西伯利亚 ( Siberia)、 帝伯 ( Tiber)、 索邦 ( Sorbonne)、罗宾娜 (Robina)、 木门 (Concad'or)、 元帅 (Acapulco) 等6个百合 (Lilium spp.) 品种的光合-光响应曲线,获得了净光合速率、 光饱和点和光补偿点等光合参数, 并探讨了净光合速率与气孔导度、 蒸腾速率、 胞间二氧化碳浓度的关系.结果表明: 6个百合品种的净光合速率与气孔导度、 叶片蒸腾速率呈极显著正相关, 但与胞间二氧化碳浓度呈极显著负相关.6个百合品种中, 罗宾娜积累物质的能力最高, 西伯利亚对光照的适应范围最广泛.
採用LI-6400XT便攜式光閤測定繫統, 研究瞭西伯利亞 ( Siberia)、 帝伯 ( Tiber)、 索邦 ( Sorbonne)、囉賓娜 (Robina)、 木門 (Concad'or)、 元帥 (Acapulco) 等6箇百閤 (Lilium spp.) 品種的光閤-光響應麯線,穫得瞭淨光閤速率、 光飽和點和光補償點等光閤參數, 併探討瞭淨光閤速率與氣孔導度、 蒸騰速率、 胞間二氧化碳濃度的關繫.結果錶明: 6箇百閤品種的淨光閤速率與氣孔導度、 葉片蒸騰速率呈極顯著正相關, 但與胞間二氧化碳濃度呈極顯著負相關.6箇百閤品種中, 囉賓娜積纍物質的能力最高, 西伯利亞對光照的適應範圍最廣汎.

The curves of photosynthesis-light response of six lily ( Lilium spp.) cultivars ( Siberia, Ti-ber, Sorbonne, Robina, Concad'or and Acapulco) were determined with portable LI-6400XT photosyn-thetic system, and a series of the photosynthetic parameters were obtained including net photosynthetic rate, light saturation points, and light compensation points.The relations between net photosynthetic rate and conductance to H2 O, transpiration race, intercellular CO2 concentration were investigated.The result showed that the net photosynthetic rate of the six lily cultivars was extremely significantly positively relat-ed to conductance to H2 O and transpiration race, while extremely significantly negatively related to CO2 concentration.Among the six lily cultivars Robina had the higherst photosynthetic rate, and Siberia could adapt to the widest range of light intensity.
