Abstract. Willows (Salix spp.) are an ancient group of deciduous shrubs and trees which has undergone an intensive phase of speciation during and after pleistocene glaciation.

The majority of willow species, in total more thanoccur in the northern temperate and boreal zone. Willow species vary greatly in their morphology and ecology: some are tiny dwarf shrubs and others grow to mid Author: J.

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.

Nectar is a sugar-rich liquid produced by plants in glands called nectaries, either within the flowers with which it attracts pollinating animals, or by extrafloral nectaries, which provide a nutrient source to animal mutualists, which in turn provide antiherbivore nectar-consuming pollinators include mosquitoes, hoverflies, wasps, bees, butterflies and moths, hummingbirds.

The term sexual dimorphism is commonly used to refer to differences in morphological, ecological and behavioral attributes resulting from the differentiation of reproductive functions between males and females and their separation into separate individuals (Meagher Cited by: This group prob ably includes the condensed tannins from the barks of Rhizophora, Bruguiera, Pinus and certain Eucalyptus species (Hillis,).

Allelopathy is a natural ecological phenomenon. It has been known and used in agriculture since ancient times (Zeng,).Allelochemicals can stimulate or inhibit plant germination and growth, and permit the development of crops with low phytotoxic residue amounts in water and soil, thus facilitating wastewater treatment Cited by:   • Eucryphia of the family Eucryphiaceae can easily be distinguished based on their glycosides • Species of Spirodella,unidentifiable on morphological grounds,can distinguish on flavonoids • Thymol and derivatives in Calea nelsonii (Martinez et al.,) • Salicylalcohol and its glycosides in Populus and Salix (Julkunen-Tiitto, a,b.

WILLOW BARK. Various species of Salix which include S. purpurea L., (purple willow) S. daphnoides Vill. and S. fragilis L. (crack willow) are sources of the official drug (BP/EP, BHP, ESCOP, Complete German Commission E).There are about species of Salix showing much hybridization and unusual forms.

They are distributed in all parts of the North Temperate Zone, the Arctic Zone and the South. Plant defense against herbivory or host-plant resistance (HPR) describes a range of adaptations evolved by plants which improve their survival and reproduction by reducing the impact of herbivores.

Plants can sense being touched, and they can use several strategies to defend against damage caused by herbivores. Many plants produce secondary metabolites, known as allelochemicals, that influence.

Many antioxidant compounds can be found in fruits and vegetables including phenolics, carotenoids, anthocyanins, and tocopherols [].Approximately 20% of known plants have been used in pharmaceutical studies, impacting the healthcare system in positive ways such as treating cancer and harmful diseases [].Plants are able to produce a large number of diverse bioactive Cited by: Certain species of ethnobotanical importance belonging to families Asteraceae, Berberidaceae, Cupressaceae, Elaeagnaceae, Gentianaceae, Salicaceae and Tamaricaceae, were collected from Gilgit during the months of June and July and were investigated for the presence of alkaloids, amino acids, anthraquinone (free and as glycosides) ascorbic acid, carbohydrates, coumarins, flavonoids, Author: A.

and Salix L., distributed chiefly in northern temperate regions (Mabberley ).Members of both genera, but in particular members of the genus Salix are noted for their propensity to produce inter-specific hybrids. This makes accurate identification of plant material difficult.

The concept of bush encroachment and invasion. Bush encroachment could be defined as an increase in woody plant abundance in grassland and savanna regions accompanied by changes in the herbaceous cover and composition of the natural vegetation [31 - 33].This section addresses the question of whether bush encroachment and/or invasion are the problem in rangelands and if the phenomenon Cited by: 3.

The strength and organization of species interactions determine the structure and dynamics of ecological communities. However, interactions do not occur between species per se – interactions occur between individuals.

A rising challenge for ecology is to understand how intraspecific trait variation scales up to affect community structure and dynamics. My dissertation research has taken an Author: Matthew A.

Barbour. Carbohydrate-rich extrafloral nectar (EFN) is produced in nectaries on the leaves, stipules, and stems of plants and provides a significant energy source for ants and other plant mutualists outside of the flowering period.

Holopainen, James D. Blande, Jouni Sorvari. The combination of biochar (BC) with compost has been suggested to be a promising strategy to promote plant growth and performance, but although “synergistic” effects have been stated to occur, full-factorial experiments are few, and explicit tests for synergism are lacking.

We tested the hypothesis that a combination of BC and spent mushroom substrate (SMS) has a positive synergistic Cited by: With o distinct species in sub-Saharan Africa alone, the African continent is endowed with an enormous wealth of plant resources.

The purpose of this book is to present the most recent advances in this field, mainly concerning the uptake and translocation of heavy metals in plants, mechanisms of toxicity, perception of metal and regulation of cell response under metal stress. in which hormones and reactive oxygen species (ROS) also play an important role.

Pathways for Chemical Synthesis Rather than totally eliminate the use of Secondary Natural Products from my writing agenda or changing its traditional meaning, I developed a system to define these plants products as Levels 1 through 4. This mimics the primary, secondary, tertiary and quaternary method of classifying products, and allows us to avoid.
