摘要: 为研究4种虾脊兰属植物光合作用的差异,了解不同种适应温室栽培的能力,为引种栽培提供理论依据,以银带虾脊兰(Calanthe argenteo-striata)、葫芦茎虾脊兰(C. labrosa)、长距虾脊兰(C. sylvatica)和三褶虾脊兰(C. triplicata)为材料,对其光响应曲线和CO2响应曲线等进行测定,并通过非线性回归拟合响应曲线。结果表明:4种植物的光合能力由大到小排序:葫芦茎虾脊兰(2.04)>银带虾脊兰(1.75)>长距虾脊兰(1.65)>三褶虾脊兰(0.83);4种植物的净光合速率随光强和CO2浓度的增加均增大;最大光化学效率排序:银带虾脊兰(0.625)>长距虾脊兰(0.583)>葫芦茎虾脊兰(0.561)>三褶虾脊兰(0.544);叶绿度排序:三褶虾脊兰(39.90)>银带虾脊兰(31.29)>葫芦茎虾脊兰(27.75)>长距虾脊兰(27.25)。银带虾脊兰和葫芦茎虾脊兰有较大的光能利用范围,对光能的适应性较强。

Abstract: This study aims to understand the difference of assimilation ability of four different kind of Calanthe species, and to compare the ability of different species to adapt to sunlight under greenhouse cultivation, thus to provide a theoretical basis for production management in facility cultivation.Taking Calanthe argenteo-striata, C. labrosa, C. sylvatica, and C. triplicata as materials, response characteristic curve of photosynthesis to the light and CO2 responses, chlorophyll fluorescence data, and relative chlorophyll contents of these four species were studied. The results showed that, according to parameters of the established response characteristic curve of photosynthesis to the light, the photosynthesis capability of four plants was C. labrosa (2.04) > C. argenteo-striata (1.75) > C. sylvatica (1.65) > C. triplicata (0.8). The rapid light curves showed that the net photosynthetic rate increased as the photosynthetic active radiation and intercellular CO2 mole fraction increased, and the rank of maximal photochemical efficiency was C. argenteo-striata (0.625) > C. sylvatica (0.583) > C. labrosa (0.561) > C. triplicata (0.544), the rank of relative chlorophyll content of the plants in the study was C. triplicata (39.90) > C. argenteo-striata (31.29) > C. labrosa (27.75) > C. Sylvatica (27.25). The comparison of the photosynthetic response parameters showed that C. argenteo-striata and C. labrosa have higher photosynthetic rate Light use range, adaptability to light energy.
