Pollination Biology of Ailanthus altissima (Mill.) Swingle (Tree-of-Heaven) in the Mid- Atlantic United States
To date little information has been collected on the pollination biology of Ailanthus altissima (Mill.) Swingle (tree-of-heaven), an invasive exotic in the U.S. This study was conducted to determine the insect pollinator fauna visiting A. altissima and to study general pollinator visitation patterns associated with the trees nectar profile. A list of taxa visiting trees within each of three si...
متن کاملBiological flora of Central Europe: Ailanthus altissima (Mill.) Swingle
Ailanthus altissima (tree of heaven), Simaroubaceae, is an early successional tree, native to China and North Vietnam, which has become invasive in Europe and on all other continents except Antarctica. It is most abundant in urban habitats and along transportation corridors, but can also invade natural habitats. This paper reviews the literature on the morphology, distribution, ecology, habitat...
متن کاملNeighbourhood analyses of the allelopathic effects of the invasive tree Ailanthus altissima in temperate forests
1. Allelopathic interactions between invasive and native species have been suggested to be an important mechanism for the success of some of the most aggressive plant invaders. However, field experiments that test the effects of natural levels of allelopathic compounds on coexisting native species are exceptionally rare. 2. In this study, we analyzed the allelopathic effects of the invasive tre...
متن کاملA New Canthinone-Type Alkaloid Isolated from Ailanthus altissima Swingle.
The present investigation of the chemical constituents of the stem barks of Ailanthus altissima has resulted in the isolation of six canthinone-type alkaloids, including a new compound, (R)-5-(1-hydroxyethyl)-canthine-6-one (1), and five known compounds (2-6). Moreover, four phenyl propanoids (7-10), two lignans (11 and 12), two triterpenoids (13 and 14) and a fatty acid (15) having previously ...
متن کاملElicitation of Canthin-6-one Alkaloid Accumulation in Cell Suspension Cultures of Ailanthus altissima (Mill.) Swingle
Cell suspension cultures of Ailanthus altissima (Simaroubaceae) were cultivated under illumination and in the dark. Under influence of a yeast elicitor and cell wall preparations of various Phytophthora species, respectively, alkaloid formation was stimulated. Canthin-6-one and 1methoxycanthin-6-one accumulation could be increased up to a 125-fold and 2.5-fold, respectively within 96 h by elici...
متن کاملAilanthus Altissima (miller) Swingle: a Source of Bioactive Compounds with Antioxidant Activity
Ailanthus altissima (Miller) Swingle is a tree used in Chinese traditional medicine as a bitter aromatic drug and in the treatment of colds and gastric diseases. Previous phytochemical studies have demonstrated the presence of quassinoids in the plant, as well as indole alkaloids. The purpose of this work was to determine the phenolic, flavonoid, and total alkaloid contents of the ethanolic, me...
