“…In this study, all subalpine fir plants exposed to a day-extension with BL rapidly developed terminal buds similar to the situation without a day-extension. In Scots pine, the application of BL or R light during germination and hypocotyl development increased the fibre dimensions compared with FR or white light [13]. In that study, a higher rate of survival in the field was observed after exposure to BL, white, and R light as compared with FR light [13].…”

“…In a range of plant species, BL affects the photosynthesis efficiency and growth rate as well as morphological characteristics like branching, stem elongation, and root growth, as well as stress tolerance [12]. In Norway spruce, low irradiances of BL provided as a day-extension delayed the terminal bud formation [7,13]. However, in subalpine fir, no such effect of BL was observed [3].…”

Blue light (BL) affects different growth parameters, but information about the physiological effects of BL on conifer seedlings is limited. In northern areas, conifer seedlings are commonly produced in heated nursery greenhouses. Compared with Norway spruce, subalpine fir seedlings commonly show poor growth in nurseries due to early growth cessation. This study aimed to examine the effect of the BL proportion on the growth and development of such conifer seedlings in growth chambers, using similar photosynthetic active radiation, with 5% or 30% BL (400–500 nm) from high pressure sodium (HPS) lamps (300 μmol m−2 s−1) or a combination of HPS (225 μmol m−2 s−1) and BL-emitting diodes (75 μmol m−2 s−1), respectively. Additional BL increased transpiration and improved the growth of the Norway spruce seedlings, which developed thicker stems, more branches, and a higher dry matter (DM) of roots and needles, with an increased DM percentage in the roots compared with the shoots. In contrast, under additional BL, subalpine fir showed reduced transpiration and an increased terminal bud formation and lower DM in the stems and needles but no change in the DM distribution. Since these conifers respond differently to BL, the proportion of BL during the day should be considered when designing light spectra for tree seedling production.

“…However, the current studies mostly selected the adequate species by statistical methods or focused on the ability of plants to accumulate heavy metals but lacked a systematic analysis of the field performance (such as height, diameter, and dry‐weight) of species. Currently, the comprehensive index, Dickson quality index (DQI) have been used to compare the performance of plants under different light conditions (Ranade & Gil, ); different fertilization conditions (Rodrigues et al, ); different N, P, and K ratios (Cuzzuol, Milanez, Gomes, Labate, & Canal, ); and different container characteristics (Chirino, Vilagrosa, Hernández, Matos, & Vallejo, ). It can also be used to predict the survival rate of plants according to their seedling morphology (Tsakaldimi, Ganatsas, & Jacobs, ).…”

Open‐pit mining results in large amounts of degraded lands that require ecological recovery. Adequate‐species selection for ecological recovery is of great importance. In this study, field investigations along the disturbance gradients (marginal area, restoration area, and control area) in a manganese ore deposit of Guangxi in Southern China were carried out. We screened the adequate species from two aspects. In the marginal area, the result of corrected Akaike information criterion revealed that Mn was the most important soil parameter affecting vegetation diversity. Cyclosorus parasiticus (L.) Farwell., Setaria viridis (L.) Beauv., Mimosa sepiaria Benth., and Bidens pilosa L. were selected for their abilities to adapt to high‐Mn‐content soils. In the restoration area and control area, we combined important values and field performance (Dickson quality index, DQI) of species to select adequate species. Miscanthus sinensis Anderss. and Arundinella hirta (Thunb.) Tanaka were selected using the similar DQI (p > 0.05) in both areas. In summary, C. parasiticus (L.) Farwell., S. viridis (L.) Beauv., M. sinensis Anderss., and A. hirta (Thunb.) Tanaka were selected as adequate species because of their high potential to adapt to these disturbed sites. Our results and methodology could have a demonstrating effect for restoration programmes in manganese ore mining areas of China.

Somatic embryogenesis is a powerful technique for forestry improvement programs when implementing multi-varietal forestry. However, it still faces some bottlenecks to be e cient in many forestry species. In this work we have studied the effect of some physico-chemical modi cations at proliferation, maturation and germination stages of Pinus radiata D. Don somatic embryogenesis, as well as the impact of this modi cations on plant conversion, survival, and on the morphology and biochemical pro le (carbohydrate and amino acid analysis) of the resulting plantlets. Given the long culture period needed for maturation and germination in radiata pine, an increase of the plant yield could be very bene cial for its commercial application.A preculture of 14 days without plant growth regulators before maturation seems to be bene cial for the development and germination of somatic embryos. Before germination, a cold storage at 4ºC had no detrimental effect and even increased plant conversion in some embryogenic cell lines. During germination, supplementation of the culture medium with glutamine and a reduction of the sucrose content can improve the greenhouse acclimatization of the plants. Similarly, germinants were demonstrated to be in uenced by the light source: uorescent light enhanced root formation, whereas blue LED light increased the shoot height of somatic plants. Moreover, the highest plants showed lower contents of arginine, asparagine and total carbohydrates. Key MessageModi cation of the physico-chemical environment before or during somatic embryo maturation and germination improves the success of the process.
