Conteúdo: 	Growth and longevity of leaves of two tree especies from the "cerrado", Vochysia rufa Mart. (Vochysiaceae) and Curatella americana L. (Dilleniaceae), were evaluated and related to intensity of herbivory. A branch from three individuals of each species was marked and all leaves followed from April 1985 to August 1986. Leaf growth, longevity and herbivory intensity measured every two weeks. Also, every three months, samples of leaves of these species were collected in order to quantify leaf damage due to herbivory with respect to the rainy and dry seasons. In both species, growth was completed by the 45th day. Leaf fall pattern differed between species. Herbivory intensity and the number of attacked leaves in V. rufa (2,9%) was lower than for C. americana (4,6%). The herbivory intensity was lower than values reported for other tropical species. Leaf longevity of both species was apparently not related to herbivory. The synchrony of the initial, fast growth of leaves with the end of the dry season and after fires seems to be an effective anti-herbivore strategy in these species, although some chemical defenses, such as high content of Al and Si may play a secondary role.
