Application of near infrared spectroscopy for authentication of Picea abies seed provenance

Authentication of seed provenance is an importance issue to avoid the negative impact of poor adaptation of progenies when planted outside their natural environmental conditions. The objective of this study was to evaluate the potential of near infrared (NIR) spectroscopy as rapid and non-destructive method for authentication of Picea abies L. Karst seed provenances. For this ...

Rescue of American chestnut with extraspecific genes following its destruction by a naturalized pathogen

Following the near-obliteration of American chestnut (Castanea dentata [Marsh.] Borkh.) by the chestnut blight early in the last century, interest in its restoration has been revived by efforts to develop a blight-resistant form of the species. We summarize progress and outline future steps in two approaches: (1) a system of hybridizing with a blight-resistant chestnut species and ...

Invasive glossy buckthorn impedes growth of red oak and sugar maple under-planted in a mature hybrid poplar plantation

Native tree seedlings (nursery produced) were planted under control and herbicide treatments in the understory of a mature hybrid poplar plantation, naturally invaded by glossy buckthorn, a major invasive exotic shrub of Eastern North America. The objectives were to (1) test the negative effect of the invasive buckthorn on seedling growth, (2) determine if this effect differed for ...

Improved growth and weed control of glyphosate-tolerant poplars

We studied the impact of glyphosate tolerance on weed control and tree growth in field-grown transgenic poplars. Using Agrobacterium-mediated transformation, we produced 94 transgenic transformation events in four hybrid genotypes (three Populus trichocarpa × P. deltoides and one of P. trichocarpa × P. nigra). These lines were screened for high levels of tolerance in two ...

Nutrient loaded seedlings reduce the need for field fertilization and vegetation management on boreal forest reclamation sites

Tree seedlings loaded with nutrients during nursery production have shown increased growth and survival relative to standard seedlings upon outplanting. We examined outplanting performance of nutrient loaded and standard trembling aspen (Populus tremuloides) seedlings, along with composition and cover of competing vegetation, on a boreal oil sands reclamation site with two ...

Tree diversity and canopy cover in cocoa systems in Ghana

Cocoa (Theobroma cacao L.) growing systems in Ghana and West Africa consist of diverse tree species and densities. This study was conducted to determine factors that influence tree species configurations and how tree characteristics affect canopy cover in cocoa farms. Eighty-six farmers and corresponding farms were selected in a systematic approach in four districts across two ...

Restoring forests: What constitutes success in the twenty-first century?

Forest loss and degradation is occurring at high rates but humankind is experiencing historical momentum that favors forest restoration. Approaches to restoration may follow various paradigms depending on stakeholder objectives, regional climate, or the degree of site degradation. The vast amount of land requiring restoration implies the need for spatial prioritization of ...

Forest restoration following surface mining disturbance: challenges and solutions

Many forested landscapes around the world are severely altered during mining for their rich mineral and energy reserves. Herein we provide an overview of the challenges inherent in efforts to restore mined landscapes to functioning forest ecosystems and present a synthesis of recent progress using examples from North America, Europe and Australia. We end with recommendations for ...

Scots pine (Pinus sylvestris L.) site index in relation to physico-chemical and biological properties in reclaimed mine soils

The aim of this work was to assess Scots pine (Pinus sylvestris L.) growth response and potential productivity on various reclaimed mine soils (RMS) developed on dominant parent rock in Poland (Central Europe). The study was conducted on four afforested post-mining sites after lignite, hard coal, sand and sulphur mining extraction. Site index (SI) was modeled as a function of the ...

Influence of mycorrhizal inoculation on growth of micropropagated Populus × canescens lines in metal-contaminated soils

Micropropagated grey poplar (Populus × canescens (Aiton) Sm.) plantlets selected during in vitro culture as tolerant to toxic Cu and Pb ions, as well as control plantlets, were inoculated ex vitro with selected strains of ectomycorrhizal fungi (Hebeloma crustuliniforme, Paxillus involutus) and an arbuscular mycorrhizal fungus (Rhizophagus irregularis BEG 87) or not inoculated, and ...

Effects of cutting size and exogenous hormone treatment on rooting of shoot cuttings in Norway spruce [Picea abies (L.) Karst.]

The effects of cutting length, cutting diameter, and exogenous hormone pretreatment on rooting were studied in comparative experiments to improve the efficiency of cutting propagation in Norway spruce. The results showed that cutting length, diameter, and the interaction between cutting length and diameter significantly affected rooting efficiency. Higher rooting efficiency was ...

An analysis of potential investment returns and their determinants of poplar plantations in state-owned forest enterprises of China

China’s state-owned forest enterprises have been important national timber production bases and their timber resources have been severely degraded during the past decades. About one-third of the state-owned forestland has been classified as commercial forestland, but no economic mechanisms have been laid out on governing timber plantations under market economy. This paper ...

Genetic aspects of age dynamics of a natural Picea abies (L.) Karst. population in the Białowieża Primeval Forest, Poland

We studied temporal changes in the genetic structure and diversity of a naturally regenerated Picea abies (L.) Karst. (Norway spruce) population in the Białowieża Primeval Forest, Poland. The analysis included five age classes of trees: newly germinating seedlings (in laboratory conditions), seedlings up to 3 years old, young trees 4–10 years old, middle-aged trees 11–100 years ...

Impact of cadmium on young plants of Populus euphratica and P. × canescens, two poplar species that differ in stress tolerance

Populus euphratica is a salt tolerant species, and Populus × canescens is a salt sensitive species. Because stress tolerance is mediated by an array of overlapping defense mechanisms, we hypothesized that P. euphratica would confer co-tolerance to heavy metal stress. To test this hypothesis, both poplar species were exposed to 50 μM Cd for 24 h in hydroponic solutions. For the ...

Development of a molecular test to determine the vitality status of Norway spruce (Picea abies) seedlings during frozen storage

In boreal forest regions, a great portion of forest tree seedlings are stored indoors in late autumn to prevent seedlings from outdoor winter damage. For seedlings to be able to survive in storage it is crucial that they store well and can cope with the dark and cold storage environment. The aim of this study was to search for genes that can determine the vitality status of Norway ...

Advances in domestication of indigenous fruit trees in the West African Sahel

Fruit trees play an important nutritional role for livelihoods of rural people in the West African Sahel through provision of energy and nutrients such as vitamins, minerals, and proteins. Research on the domestication of local fruit trees has started recently through projects concentrating on some of the most important indigenous species of dry West Africa, i.e. Adansonia ...

Limited response to nursery-stage mycorrhiza inoculation of Shorea seedlings planted in rubber agroforest in Jambi, Indonesia

We transplanted Shorea selanica and Shorea lamellata seedlings that either had or had not received ectomycorrhiza (EcM) Scleroderma columnare inoculum, commercially available and prescribed as standard practice in nursery, into rubber gardens of different age and plot history. The objective was to assess whether or not absence of fungal inoculants restricted seedling survival, ...

Estimation and economic evaluation of aboveground carbon storage of Tectona grandis plantations in Western Panama

Tropical tree plantations may play an important role in mitigating CO2 emissions through their potential to capture and sequester carbon from the atmosphere. The Clean Development Mechanism (CDM) as well as voluntary initiatives provide economic incentives for afforestation and reforestation efforts through the generation and sale of carbon credits. The objectives of our study were ...
