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

Abstract

This study aimed to add research efforts in knowledge of the multiple use of C. guianensis, focusing on the production of seedlings and extraction procedures aimed oil to small rural producers. It was structured in the form of chapters, the first of which focuses on the production of seedlings from different 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. The collected seeds were subjected to sand storage environment, water, refrigerator and natural (outdoor) for three periods of storage, they are 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 was checked the oil yield and its chemical composition from the influence of the four storage methods. The experiments were performed in the garden of medicinal plants at Embrapa Amazônia Oriental, in Belém-PA. In this chapter it was found that the yield of seeds from storage in 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.
