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.

Science and technology are highly progressing in different domains towards safe and healthy food products originated from sustainable supply chains. Ohmic sciences combined with novel food processes empowered by digital technologies may contribute to optimized cyber physical ecosystems for food, biofuel or biomaterials production. Multifunctional institutions with multidisciplinary expertise are required for an efficient and optimized ecosystem aiming at achieving a more balanced and effective outcome. Knowledge translation and capacity building are key factors for innovation driven ecosystems by integrating education and training actions. Infrastructure sharing and expertise synergy in national and international cooperation may enhance the potential and competitiveness for innovation for a broader and more equal social and economic global development. |
