Hermaphroditism in the rubber tree Hevea brasiliensis (Willd. ex Adr. de Juss.) Muell. Arg. - II

flowers of three hevea brasiliensis clones, rrim 527, rrim 600 and gt 1, were analyzed under stereomicroscope and scanning electron microscope, aiming to observe hermaphroditism rates. results showed 71.49% hermaphrodite flowers, 29.83% of which exhibited incompletely developed, residual anthers. the scanning electron microscope analysis did not detect differences in anther epidermis of male and bisexual flowers of rrim 600 and rrim 527. in gt 1 clone (sterile male), the anther epidermis was already weak at the beginning of floral development and completely wrinkled at the end of maturation. consequently, the anthers were empty by this stage.
