Morfologia de frutos, sementes, plântulas e mudas de Senna multijuga var. lindleyana (Gardner) H. S. Irwin & Barneby – Leguminosae Caesalpinioideae

Abstract

(Morphology of fruits, seeds and seedlings of Senna multijuga var. lindleyana (Gardner) H. S. Irwin & Barneby – Leguminosae Caesalpinioideae). We described and illustrated the external and internal morphology of fruits and seeds and the external morphology of seedlings of Senna multijuga. The work was carried out in laboratory and forest nursery conditions. We detected useful characters to identify this species both in laboratory (in seed analyses) and field studies (ecology and regeneration). The main fruit characters described were: dehiscence, shape, color and pericarp texture. The main seed characters described were: closed pleurogram, shape and persistence of cotyledons, areole and endosperm; of the seedlings: aspects of young stem, shape and persistence of cotyledons, leaf arrangement, presence of hair and glands and shape of eophyll.
