摘要
目的研究鸡骨草、毛鸡骨草在开花结荚期的光合特性。方法应用TPS-1便携式光合作用测定系统测定两种植物的光合作用变化。结果鸡骨草、毛鸡骨草都具有光合"午休"现象,毛鸡骨草的光合性能强于鸡骨草。结论两种植物光合速率(Pn)的日变化主要受气孔和非气孔因素共同作用的结果。
Objective To study the photosynthetic characteristics of Abrus cantoneinsis and Abrus mollis at the flowering pods stage. Methods Photosynthesis changes of the two plants were measured through TPS - 1 portable photosynthesis system. Results Abrus cantoneinsis and Abrus mollis had a clear ＂midday depression＂ , photosynthetic performance Abrus mollis of was better than that of Abrus cantoneirtsis. Conclusion The two species of diurnal variation Pn mainly are influenced by stomatal and non-stomatalfactors.
