In boreal woody plants, concentrations of defensive phenolic compounds are expected to be at a high level during the juvenile phase and decrease in maturity, although there is variation between plant species. Females of dioecious species, like most of the Salicaceae, are expected to invest their
Combined enhancements of temperature and UVB influence growth and phenolics in clones of the sexually dimorphic Salix myrsinifolia.

Although several climatic factors are expected to change simultaneously in the future, the effect of such combined changes on plants have seldom been tested under field conditions. We report on a field experiment with dark-leaved willow, Salix myrsinifolia, subjected to enhancements in ultraviolet-A
Effects of long-term UV-exposure and plant sex on the leaf phenoloxidase activities and phenolic concentrations of Salix myrsinifolia (Salisb.).

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. The effects of UV-B radiation have mainly

Nine S. MYRSINIFOLIA clones were studied for secondary phenolics and phytomass production in an old, unfertilized hayfield after the second growing season. S. MYRSINIFOLIA is one of the most promising willow species for the production of herbal drug material. Its salicylate content is moderately
Dry-air drying at room temperature - a practical pre-treatment method of tree leaves for quantitative analyses of phenolics?

BACKGROUND
In ecological experiments, storage of plant material is often needed between harvesting and laboratory analyses when the number of samples is too large for immediate, fresh analyses. Thus, accuracy and comparability of the results call for pre-treatment methods where the chemical
The vegetative buds of Salix myrsinifolia are responsive to elevated UV-B and temperature.

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 effects on buds have rarely been
Dark-leaved willow (Salix myrsinifolia) is resistant to three-factor (elevated CO2, temperature and UV-B-radiation) climate change.

Elevated carbon dioxide (CO2 ), temperature (T) and ultraviolet-B (UV-B) radiation may affect plant growth and secondary chemistry in different directions, but the effect of the combination of the three factors has seldom been tested. Here, we grew four dark-leaved willow (Salix myrsinifolia) clones
Increased CO2 and nutrient status changes affect phytomass and the production of plant defensive secondary chemicals in Salix myrsinifolia (Salisb.).

The effect of CO2 enrichment (700 and 1050 ppm) on phytomass, soluble sugars, leaf nitrogen and secondary chemicals of three Salix myrsinifolia clones was studied in plants cultivated at very poor (sand seedlings) and moderate (peat seedlings) nutrient availability and under low illumination. The
Gender differences in Salix myrsinifolia at the pre-reproductive stage are little affected by simulated climatic change.

Females of dioecious species are known often to prioritize defense, while males grow faster. As climatic change is known to influence both growth and defense in plants, it would be important to know whether it affects the sexes of dioecious species differently. This could have impacts on future sex
Salicylates of intact Salix myrsinifolia plantlets do not undergo rapid metabolic turnover.

Salicylates, the main phenolic glucosides of northern willow (Salix spp.), play an important role in plant-herbivore interactions. Salicylates are labile metabolites that are thought to undergo metabolic turnover. Salicylates are synthesized from phenylalanine (Phe) via the shikimate pathway.

The role of pathogens in insect ecology is widely appreciated but remains insufficiently explored. Specifically, there is little understanding about the sources of the variation in the outcome of insect-pathogen interactions. This study addresses the extent to which immune traits of larvae and pupae

We studied the effects of natural wounding by insects and artificial wounding by clipping with scissors on the phenolic chemistry of two willows, Salix myrsinifolia and Salix pentandra. Half of the blade of a mature leaf was removed from each experimental plant either by allowing insects
