Morfologia foliar de Theobroma grandiflorum Schum Foliar morphology of Theobroma grandiflorum Schum

Abstract

As folhas de Theobroma grandiflorum Schum. são morfologicamente descritas. A espécie apresenta elementos histológicos comuns para a família, destacando-se tipos de tricomas, estômatos e contornos das células epidérmicas em visão frontal. Empregou-se microscopia eletrônica de varredura para a caracterização de segmentos foliares jovens, em que ficou evidenciada a presença de tricomas estrelados nas superfícies adaxial e abaxial dos mesmos. As folhas de cupuaçu são hipoestomáticas com número elevado de estômatos anomocíticos. As nervuras principais apresentaram-se desprovidas de tricomas, com estômatos esparsamente distribuídos.The cupuassu leaves are morphologically described. The species present common histological elements in the family, showing types of trichomes, stomata and epidermal cells on the surface view. Young foliar segments were photographed with scanning electron microscopy, where trichomes with star form were detected in the adaxial and abaxial epidermis. The cupuassu leaves are hypostomatic with high numbers anomocytic stomata. The main veins of the cupuassu leaves did not show trichomes, and stomata were sparsely distributed.
