Carex parva and Carex scabrirostris adopt diverse response strategies to adapt to low-light conditions

In terms of response strategies, <i>C. scabrirostris</i> is a high-photosynthesis investing species with high productivity under low-light conditions, whereas <i>C. parva</i> exhibits minimal response, indicating a slow investment. <i>C. scabrirostris</i> has greater potential for application in low-light environments compared to <i>C. parva</i>. These results provide a theoretical basis for the cultivation and application of these two <i>Carex</i> species, as well as the expansion of turfgrass germplasm resources.
