Use of innovative technology for the production of high-quality forest regeneration materials

Light quality and intensity of light-emitting diodes during pre-cultivation of Picea abies (L.) Karst. and Pinus sylvestris L. seedlings – impact on growth performance, seedling quality and energy consumption

“…The results from measurements of shoot height and shoot diameter support the suggestion that LED lamps are an alternative to conventional light sources since seedlings precultivated under LEDs in this study performed in comparable ways. These findings are supported by other studies within this field of research (for example Mattsson et al 2010;Apostol et al 2015b;Riikonen et al 2016;Smirnakou et al 2017). In addition, LEDs can offer advantages such as potential reduction in energy consumption, low directional thermal output, adjustable light intensity and prolonged life span (Gerovac et al 2016).…”

“…Although the use of LED lamps in horticulture is rapidly establishing as an effective and reliable practice (Mitchell et al 2015), there are still relatively few studies conducted on tree species. Some of these studies involve broadleaves such as beech, holm oak, wild cherry (Astolfi et al 2012), common dogwood (Bantis and Radoglou 2017) and conifers such as Douglas fir, Engelmann spruce (Apostol et al 2015b), Bulgarian fir, Scots pine and Norway spruce (Mølmann et al 2006;Mattsson et al 2010;Riikonen et al 2016;Smirnakou et al 2017). However, these studies have been conducted under a fixed PAR intensity of approximately 100-300 μmol m −2 s −1 for the entire seedling cultivation.…”

Did Ecological Restoration Hit Its Mark? Monitoring and Assessing Ecological Changes in the Grain for Green Program Region Using Multi-source Satellite Images

“…Responsible forest management could be promoted by bringing in market-based third-party certification for evaluating forests according to a set of standards [97,98]. Improving the biological, physiological, and genetic quality of forest planting stock through plant biotechnology, a high level of environmental control in the growth chambers, and transnational co-operation are also practical ways to carry out forest restoration projects [99][100][101][102]. International climate change mitigation programs, which are designed to reduce emissions from deforestation and forest degradation in developing countries (REDD+), should also be taken into consideration as collateral payments for the substantial carbon benefit in maintaining forest [103].…”

Treatments for induction of cold hardiness inPicea abies(L.) Karst. andPinus sylvestrisL. seedlings pre-cultivated under light-emitting diodes – impact of photoperiod and temperature including energy consumption and seedling quality after cold storage

“…As an alternative to current nursery practices, a novel concept for year-round cultivation of forest seedlings has been under development during the past decade (Mattsson et al 2010;Astolfi et al 2012;Riikonen et al 2016;Bantis and Radoglou 2017). The new approach consists of a seedling pre-cultivation phase under light-emitting diodes (LED) using high container densities inside of a growth room facility followed by transplanting to larger containers for an outdoor growth phase without using greenhouses.…”
