The aim of this study is to evaluate the responses of 'Tahiti' lime fruits to different range of wetted soils on gassed changes, fruit development, productivity and quality. The experiment will be performed at Areão ESALQ/USP Farm, Piracicaba, SP, BR, in a 1 ha orchard with a space of 7 x 4 m with dropping irrigation. For the gassed change lectures it will be used the infrared gas analyzer (IRGA), and for determination of plant water potential it will be used the Scholander camera. The water stock will be obtained considering the whole lysimeter profile, as well as the root water extraction, checked by potential matrix sensors and soil humidity. The evaporate-transpiration of reference will be estimate by Penman-Monteith FAO-56, basead on meteorological data given by an automatic station (datalogger), present in the area.
