Influência das condições e período de armazenamento na germinação, formação de mudas e rendimento do óleo de Carapa guianensis AUBL. (Meliaceae).

Abstract

Brazil has a vast plant diversity and various experiments linked to popular knowkdge of medicinal plants, with most of their agricultural production traditionally grounded in Agroforestry System (AFS). The species Carapa guianensis known as andiroba, occurs naturally throughout the Amazon. It is a tree belonging to the family of Meliaceae and officially recognized by the Ministry of Health of Brazil for its herbal properties from the oil from its seeds. It is a potential species for recovery and restoration of degraded areai of the legislation, as the areas of Legal Reserve (RL) and Permanent Preservation Áreas (PPAs). Thus, it is essential to invest in research activities aimed at knowledge related to emergency, conservation of seeds and the extraction of its flagslnp product that are essential for the perpetuation and economic and environmental valuation of this kind. This study aimed to add research efforts in knowledge of the multiple use of C. guianensis, focusing on seedling production and extraction procedures facing the oil to small farmers. It was stmctured in the form of chapters. the first of which focuses on the production of seedlings from d fferent methods and C. guianensis seed storage periods, in order to verify the influence of the method in the emergence of seedling in its growth and survival. In the second chapter was chec ced the oil yield and its chemical composition from the influence of the four storage methods. The experiments were performed in the nursery garden of medicinal plants of Embrapa Amazônia Oriental, Belém-PA. The collected seeds were submitted to the sand storage environments, water, and natural refrigerator for three periods of storage, namely 4, 8 and 12 days In the first chapter the majority of the variables analyzed was affected by seed storage process, and the environment, water and sand those who most influenced the growth of the species when sown after four days of storage, compared to the plants grown from seeds stored in refrigerator .In the second chapter it was found that the yield of seeds from storage n sand and water oil had higher values compared to from seeds stored in natural and refrigerator, inferring that the seed storage influenced the andiroba oil income.
