Conteúdo: 	This paper reports on further studies of a model for interpreting kaf water potencial data for Citrus. Experimental data confirmed the assumption that the ratio of vapor pressure deficit to leaf diffusion resistance adequately estimates transpiration when kaf-to-air temperature differences are small. Data collected diurnally indicated that the relationship between leaf water potential and transpiration followed a sequence of steady states without hysteresis. No difference in water trnasport characteristics was found for Valencia orange on three rootstocks in well-watered soil, but the two rootstock Cleopatra mandarin and Rangpur gave slightly greater leaf water stress in Valencia orange leaves than "Troyer" citrange rootstock at high transpiration rates under mild soil water deficits. In laboratory studies, previously unstressed seedlings had higher leaf water potentials than field trees at equivalent transpiration rates. After several dryng cycles, hower, leaf water potentials were similar to those observed in the field.
