CAM Plants for Green Roofs The Potential in Desert Species That Perform Crassulacean Acid Metabolism
University Joseph Abstract: Succulence and the ability to perform crassulacean acid metabolism, a processClassroom Research Problem: The most extensively studied green roof Valasquez Storage
270U2 during daylight272 280 of CAM plants that cannot tolerate by which plants limit gas exchange with their environment hours, are often cited 274 plant materials are sedums, a genus as reasons why temperate climate Sedum species are successful as green roof materials. While 297sf the extreme conditions of the170sf arid Southwest 94sf Sedum are not adapted to the hot arid climate of Phoenix, many species of CAM plants including John CAM plants, including agaves and cacti are native or adapted here. In order test the suitability of four native species, Research Question: Can arid-adapted M.to Kroelinger Takamura Ozel twenty pre-fabricated plastic green roof modules wereF. purchased from a manufacturer in Mexico agaves and cacti provide similar ecosystem service benefits as sedums if B.
