Accumulation of phenolics and growth of dioecious Populus tremula (L.) seedlings over three growing seasons under elevated temperature and UVB radiation.

Journal Article Plant physiology and biochemistry : PPB · August 2021 Accumulation of secondary metabolites may exhibit developmentally regulated variation in different plant organs. Moreover, prevailing environmental conditions may interact with development-related variations in plant traits. In this study, we examined deve ... Full text Cite

Genetic modification of the flavonoid pathway alters growth and reveals flexible responses to enhanced UVB - Role of foliar condensed tannins.

Journal Article Plant-environment interactions (Hoboken, N.J.) · February 2021 Accumulation of certain phenolics is a well-known response of plants to enhanced UVB radiation (280-315┬ánm), but few experiments have compared the relative importance of different phenolic groups for UVB resilience. To study how an altered phenolic profile ... Full text Cite

Phytochemical Shift from Condensed Tannins to Flavonoids in Transgenic Betula pendula Decreases Consumption and Growth but Improves Growth Efficiency of Epirrita autumnata Larvae.

Journal Article Journal of chemical ecology · February 2020 Despite active research, antiherbivore activity of specific plant phenolics remains largely unresolved. We constructed silver birch (Betula pendula) lines with modified phenolic metabolism to study the effects of foliar flavonoids and condensed tannins on ... Full text Cite

Interannual variation in UV-B and temperature effects on bud phenology and growth in Populus tremula.

Journal Article Plant physiology and biochemistry : PPB · January 2019 Warming affects phenological processes such as spring bud break and autumnal bud set, and also growth rates of trees. Recently, it has been shown that these physiological processes also may be influenced by the ultraviolet-B (UV-B) part of the solar spectr ... Full text Cite

Does fungal endophyte inoculation affect the responses of aspen seedlings to carbon dioxide enrichment?

Journal Article Fungal Ecology · June 1, 2018 Endophytes are microorganisms that live inside plants without causing visible symptoms, at least during some parts of their life cycle. We studied, for the first time, the combined effects of CO2 enrichment (700 ppm) and fungal endophyte inoculation on the ... Full text Cite

Effects of long-term UV-exposure and plant sex on the leaf phenoloxidase activities and phenolic concentrations of Salix myrsinifolia (Salisb.).

Journal Article Plant physiology and biochemistry : PPB · May 2018 The accumulation of flavonoids on the leaf surface is a well-characterized protective mechanism against UV-B radiation. Other protective mechanisms, such as the induction of antioxidative enzymes and peroxidase-mediated lignification may also be important. ... Full text Cite

Growth and defence of aspen (Populus tremula) after three seasons under elevated temperature and ultraviolet-B radiation

Journal Article Canadian Journal of Forest Research · January 1, 2018 The predicted climate change will affect the growth and secondary chemistry of plants, but most studies only include leaves and leave out the effects on the secondary chemistry of other plant parts. In a field experiment, we studied the stem phenolic chemi ... Full text Cite

Effect of climate change on bud phenology of young aspen plants (Populus tremula. L)

Journal Article Ecology and Evolution · October 1, 2017 Boreal tree species are excellent tools for studying tolerance to climate change. Bud phenology is a trait, which is highly sensitive to environmental fluctuations and thus useful for climate change investigations. However, experimental studies of bud phen ... Full text Cite

Responses of growth and leaf phenolics in european aspen (Populus tremula) to climate change during juvenile phase change

Journal Article Canadian Journal of Forest Research · January 1, 2017 In trees, the change from juvenile to adult vegetative phase can last for years. In Populus tremula L., this phase change is characterized by a morphological change in leaf shape, as leaves in the seedling phase typically are sharp-tipped, while saplings a ... Full text Cite

Interactive effects of supplemental UV-B and temperature in European aspen seedlings: Implications for growth, leaf traits, phenolic defense and associated organisms.

Journal Article Plant physiology and biochemistry : PPB · August 2015 Past studies reveal opposite effects of elevated UV-B and temperature on plant growth and concentrations of UV-B absorbing compounds, yet few studies have dealt with the combined and interactive effects of these two climate change factors on woody dioeciou ... Full text Cite

The vegetative buds of Salix myrsinifolia are responsive to elevated UV-B and temperature.

Journal Article Plant physiology and biochemistry : PPB · August 2015 The predicted rise in temperature and variable changes in ultraviolet-B radiation will have marked effects on plant growth and metabolism. Different vegetative parts of trees have been studied to detect the impacts of enhanced temperature and UV-B, but the ... Full text Cite

Boreal woody species resistance affected by climate change

Chapter · January 1, 2015 Climate change undoubtedly affects the metabolism and resistance of woody plants, and results in changes in their competitive management. Due to low climatic niche evolution, trees and shrubs are slow to react to climate change. In addition, current studie ... Cite

Long-term UV-B and temperature enhancements suggest that females of Salix myrsinifolia plants are more tolerant to UV-B than males

Journal Article Environmental and Experimental Botany · January 1, 2015 Males of sexually dimorphic trees and shrubs are hypothesized to have lower reproduction costs, to grow faster and to be less well defended than females. Sex-related differences in sexual reproduction, photosynthesis, growth, phenolic concentrations and ru ... Full text Cite

Sex-related differences in growth and carbon allocation to defence in Populus tremula as explained by current plant defence theories.

Journal Article Tree physiology · May 2014 Plant defence theories have recently evolved in such a way that not only the quantity but also the quality of mineral nutrients is expected to influence plant constitutive defence. Recently, an extended prediction derived from the protein competition model ... Full text Cite

Water use strategies of seedlings of three Malagasy Adansonia species under drought

Journal Article South African Journal of Botany · July 1, 2012 Adansonia species, known by the common name "baobab," have a very low regeneration rate in Madagascar. In order to determine if Malagasy Adansonia seedlings' vulnerability to drought may account for this low rate of regeneration, we compared growth, photos ... Full text Cite
