Study on the Physiological and BiochemicalResponses of N. grossedentata to Karst Soil

Severe rocky desertification and soil erosion, frequent occurrences of droughts and floods, recurrent karst collapses, and the degradation of groundwater quality constitute the most urgent ecological challenges currently facing karst regions [1].Since the early 21 st century, these challenges have been central to the focus of karst researchers.Considering the inherent features of rocky desertification regions -characterized by high rock exposure, limited and shallow soil presence, soil aridity, and increased calcium levels [1, 2] -plants selected for mitigating karst desertification must possess drought tolerance, lithophilous properties, a preference for calcium, and strong, well-developed root systems.Multiple studies have evidenced that climbing plants exhibit significant adaptability, rapid growth, and extensive root systems due to their capability to grow by adhering to supports such as rocks, other vegetation, and cliffs.These plants are distinguished by their substantial biomass, minimal ground space requirements, extensive coverage, and inherent mobility and resilience to degradation [3,4].These traits allow them to rapidly establish vegetation cover in rocky desertification
