匍茎翦股颖 (Agrostis stolonifera)为禾本科翦股颖属冷季型 C3植物 ,2 n=2 x=14。具有相对较高的光饱和点 (5 0～ 15 0 mg/ L CO2 浓度 ) ,光呼吸释放的 CO2 为光合作用同化 CO2 的 1/ 3左右 ,是一种高光呼吸植物 ,在贵州省境内野生资源分布极广 ,是贵州地区值得推广的一种优?
Agrostis stolonifera is a cold-season C3 plant of the genus Poaceae, with 2 n = 2 x = 14. Has a relatively high light saturation point (50 ~ 150 mg / L CO2 concentration), CO2 released by photorespiration is about 1/3 of photosynthetic CO2 assimilation, and is a kind of high light respiration plant. Widely distributed, it is worth promoting a good area in Guizhou?
