%X this work aimed to compare some aspects of the leaf-gas exchange and water balance of two field grown cultivars (fx 3864 e rrim 600) of the rubber tree. measurements were carried out for two months between the wet and dry seasons of 2001 and 2002. integrated values of gas exchange showed a decrease in photosynthesis (32% and 22%), transpiration (44% and 38%), and stomatal conductance (29% and 17%) for rrim 600 and fx 3864, respectively. osmotic potential decreased by 41% for rrim 600, and by 36% for fx 3864. the results suggest that the performance of fx 3864 was similar to that of rrim 600 throughout the year at the juvenile stage studied.
