Evolução da ontogenia foliar em plantas de cupuaçuzeiro Theobroma grandiflorum Schum sob condições semi-controladas.

Abstract

The Cupuaçu Theobroma grandiflorium schum, has been awakening as a fruit of great economic potential, although it is still exploited in an extractive way. In recent years the increase in the area planted with this species has made possible the increase in the incidence of the disease "vossoura-de-bruxa", caused by the fungus Crenipellis perniciosa. To date, little is known about the biology and epidemiology of the fungus and its effect on the physiology of the plant, which is always measured by the decrease in production. In the present work, the behavior of the leaf ontogeny of cupuaçu seedlings was studied, aiming to obtain basic parameters that can help in the understanding of the physiological responses of plants against infection by the pathogen.
