Abstract: The stem heat balance method (HBM) measures sap flow (SF) in plants, and can be used to estimate daily transpiration flow. It is a powerful technique for water relations and irrigation field studies, but it has to be tested in species of particular interest. This paper discusses effectiveness of the HBM to estimate transpiration of young acid lime plants (Citrus latifolia Tan. cv. Tahiti), grafted on citrumelo cv. Swingle (Poncirus trifoliata Raf. x C. paradisi Macf.), in the field using commercial gauges (mod…
