Changes in the photosynthetically active radiation (PAR) levels to which a certain species are adapted can result in different plant growth responses. Thus, analytical and systematic studies on the mechanisms that plant species use to survive when subjected to changes in PAR are required. To address the lack of literature on this topic for Ananas comosus, this study aimed to evaluate the effects of different PAR levels on the growth of this species. A completely randomised experimental design was used consisting of subdivided plots containing a total of 1176 forest plants, including 1040 Sc (Schizolobium parahyba subsp. amazonicum), 96 Cg (Cordia goeldiana Huber), 40 Sw (Swietenia macrophylla King), and 13.000 An (Ananas comosus var. erectifolius) agricultural plant species. Seven treatments were established based on this combination of species. These treatments were installed using a completely randomised block design with split plots. Each plot measured 18 m x 24 m, and each treatment was replicated four times, resulting in a total of 28 plots and an experimental area of 12.096 m². After establishing the treatments, studies were conducted to evaluate the influence of different radiation levels on An plant growth. In this study, pluviometric precipitation data and mean percentage values (53, 64, 71 and 100%) of PAR (?mol m-² s-1) were recorded. Over the period between 2003 and 2006, the number of leaves, the lengths of the leaves, and the number of An sprouts were measured every six months. The highest number of leaves was recorded in the treatments in which the plants were exposed to 64% PAR. The number of leaves in this treatment was similar to that in the 71% PAR treatment. However, the number of leaves decreased in the plants that were subjected to either the highest (100%) or the lowest (53%) level of PAR. The use of different PAR levels for An plants under cultivation conditions showed that the best growth rates of the leaves and shoots were associated with lower levels of PAR (53% and 64%). However, cultivation under full sunlight favoured a higher number of leaves. The fibre, leaf and mucilage production progressively increased until the third year of the experiment.

O Acre é um dos maiores produtores de farinha da Amazônia e sua produção está concentrada na Regional do Juruá. A farinha de mandioca de Cruzeiro do Sul, vem sendo fabricada artesanalmente há mais de 100 anos. O objetivo deste trabalho foi demonstrar as experiências da Embrapa Acre com as populações não indígenas e indígenas, produtoras da farinha de mandioca conhecida como farinha de Cruzeiro do Sul, bem como caracterizar os aspectos tecnológicos que sobressaíram ao longo do tempo, conquistando notoriedade perante os consumidores. |
