Technological advances in agriculture make it possible to manage the light spectrum radiation a protected environment and generate improvements plant photomorphogenesis, which can be promising strategy for supply of seedlings pomegranate qualities. It aimed evaluate whether microclimatic environmental changes, due management radiation, modify photomorphogenesis water consumption by cuttings treated with aqueous C. rotundus (nutsedge) extract, as well determine most important variables explain such effects. A completely randomized design, 4x4 factorial scheme, three replications. Four (white, blue, red, extreme red lights) four nutsedge extract concentrations (0, 25, 50, 100%) were applied. Throughout experimental period, environments monitored establish illuminance, average air temperature, relative humidity, soil temperature evapotranspiration cuttings. The numbers shoots recorded weekly, roots calculated 60 days after cutting planting. All influenced conditions. Shoots observed on under white blue lights application 0, 100% concentrations. Variations promote microclimate changes influence nutsedge. studied considered variation,
