Respostas ecofisiológicas de Aniba parviflora ao sombreamento

Abstract

Com o objetivo de avaliar as respostas ecofisiológicas de mudas de macacaporanga (Aniba parviflora) em diferentes níveis de sombreamento foi conduzido um experimento no viveiro de mudas da Universidade Federal do Oeste do Pará, em Santarém-PA. Os níveis de sombreamento foram 30%, 50% e 70% de sombreamento e a pleno sol com 0% de sombreamento. O delineamento foi inteiramente casualizado, com quatro repetições, das quais cada uma foi composta por cinco plantas. Foram avaliados altura, diâmetro, número de folhas, área foliar, área foliar específica, massa seca da raiz, caule, folhas e total, taxa assimilatória líquida, condutância estomática, transpiração, eficiência do uso da água e teores de clorofila. Os maiores valores para altura, área foliar e área foliar específica foram obtidos sob 70% de sombreamento, no entanto, para diâmetro e número de folhas os maiores valores foram sob 50% de sombreamento. O sombreamento de 70% proporcionou os maiores valores na taxa assimilatória líquida, condutância estomática, transpiração, eficiência do uso da água, clorofilas a, b e total. O sombreamento de 50% ocasionou os maiores valores na massa seca de raiz, caule, folhas e total. O nível de sombreamento de 50% proporcionou o melhor crescimento e desenvolvimento das mudas.
