Limitations to photosynthesis were examined for Encelia farinosa Toney et A.Gray, a common C3 sub-shrub in arid regions of south-westem United States, for plants grown in full sunlight and those shaded to 40% of full sunlight. Encelia farinosa, grows well in most of Southern California with no water after the first few months. Brittlebush (Encelia farinosa, USDA zones 8 through 11) has silvery white leaves covered with reflective, white hairs that can reduce the plant's temperature by several degrees. It can also be found on hillsides and valleys in Hawaii. The effects of leaf hairs on photosynthesis, transpiration, and leaf energy balance were measured on the desert shrub Encelia farinosa in order to determine the adaptive significance of the hairs. It blooms during the rainy season – most often beginning in February and continuing even into May. At both sites, temperature has increased at a rate of ∼0.04 °C per year, and VPD has increased at … The two habitats contrasted sharply in air temperature, atmospheric vapor pressure deficit, and precipitation.
