Seasonal Coloration and Ecological Adaptations of Adventitious Roots of Four Salicaceous Species in Jiuzhaigou World Natural Heritage Site, Southwestern China.

ABSTRACT: Jiuzhaigou is a world natural heritage with extraordinary beauty of wetlands largely developed on tufa landforms. The wetlands are dominated by shrubs and trees. A striking feature of dense and plentiful adventitious roots is found during summer, and the color changes to unnoticeable during winter. Despite the visual prominence of this phenomenon, its biochemical mechanisms and ecological significance remain unexplored. Integrating field surveys, anatomical analyses, and biochemical profiling to decipher coloration dynamics and their potential as environmental bioindicators, results indicate that dense adventitious roots were found only with willow and poplar species in the tufa wetlands in Shuzheng and Rize valleys. Adventitious roots displayed specialized adaptations, including well-deve
