Umedecimento do substrato, temperatura na germinação e vigor de sementes de Bixa orellana L.

Abstract: Resumo: A Bixa orellana L., é uma planta originária da América Tropical, pertencente à família Bixaceae, cujos frutos são cápsulas recobertas de espinhos, ovóides que contém em torno de 40 a 50 sementes e possuem um pigmento natural muito utilizado na indústria alimentícia. Estudos sobre a germinação do urucum são essenciais para otimizar a propagação sexuada, em relação a temperatura e ao volume de água no substrato, papel toalha Germitest, que melhor expresse a germinação . O objetivo foi avaliar diferentes … Show more

“…For E. phaeotricha seeds, substrate moistening at levels lower than 2.0 or higher than 2.5 times the dry weight of the paper led to reduction in germination, due to the lower production of normal seedlings and germination speed. Probably, at moistening levels lower than 2.0 times the dry weight of the paper, water availability was insufficient to trigger the germination process, as observed in seeds of Melaleuca quinquenervia and Bixa orellana L. (Martins et al, 2011;Sousa et al, 2015). At moistening levels higher than 2.5 times, the excess water in the substrate must have hindered seed germination due to the lower aeration.…”
