Growth and development of plants depend on the spectral composition and the intensity of the available light. To minimize energy costs and optimize the growth and quality of plants, the light intensity and color is essential in artificial lighting systems. As a rule, in both commercial and scientific applications, the light intensity should be homogeneous and of a controlled spectral composition. Light-emitting diodes (LEDs) offer a flexible approach to high-intensity light sources allowing for a well-regulated spectral composition, and are increasingly used in commercial crop production. The strongly focused light beam in many LED arrangements maximizes the radiation transmission to plants, but can lead to a very heterogeneous light. Although a greater distance between the light source and the plants can partially solve the problem, this also results in wasted light energy that does not benefit the plants. Therefore, it seems obvious to use optical measures such as lenses or reflecting surfaces to achieve uniform light. This project is designed to analyze the potential for the use of innovative lighting optimization solutions in the stimulation of plant growth. The aim of the project is to investigate the use of optical light-steering films to optimize the use of light by plants under artificial lighting.

Starting in 2016, an area of 14.6 ha will be reforested with the involvement of the local community in Costa Rica. A substantial number of native tree species will be planted, and the growing new rainforest will act as a carbon sink. We estimate that 4400 tons of CO2 will be sequestered by the aboveground and belowground biomass. The growing forest will additionally become part of a biological corridor, enabling plants and animals to migrate between the lowland and the montane forests. Training local stakeholders should ensure that the project is supported by the community and increase understanding and appreciation of conservation.

The objective of TOPWOOD is to build a four-year scientific exchange program about the development of medium and high-throughput phenotyping measurement and analysis tools for selected basic wood properties in the laboratory and in the field (TOols for Phenotyping WOOD-TOPWOOD). The participants wish to exchange knowledge and experience for sharing and expanding skills, improving existing tools and developing new original measuring devices. The phenotyping tools and the methods of analysis developed and improved in TOPWOOD are intended to be used by the participants to investigate the genetic and environmental determinism of key wood properties involved in forest tree adaptation, wood production, quality of stem wood and profitability of the forest-wood chain. The participants of TOPWOOD are three academic institutions and two private companies from three European Union countries, Austria, France and Spain, and one third country, Argentina.
