Hydraulic strategy of cactus trichome under arid environment




2018.01.02 15:57

 Being an essential component in various metabolic activities, water is important for the survival of plants and animals. Cacti grown in arid areas have developed intrinsic water management systems, such as water collection through spines, water absorption through trichome, and water storage using mucilage. This study analyzed the morphology and wettability of cactus trichomes by using advanced bio-imaging techniques and by performing experiments on an artificial system mimicking these structures, respectively. In addition, the in situ water absorption process through the trichome cluster was quantitatively visualized.
