Classificação de sementes de espécies florestais dos gêneros Nectandra E Ocotea (Lauraceae) quanto ao comportamento no armazenamento

Abstract

Studies on seed storage behaviour allow the establishment of suitable conditions to maintain seed viability, in order to support programs of ex situ conservation and seedling production. Thus, this study aimed to investigate the seed storage behavior of five species of the Lauraceae family which grow in South of Minas Gerais State, Brazil. Seeds of Nectandra grandiflora, Nectandra lanceolata, Nectandra oppositifolia, Ocotea corymbosa and Ocotea pulchella were assessed regarding germination and moisture content before and after artificial drying. The seeds show recalcitrant behaviour due to their desiccation sensitivity.
