Allelopathic Potential of the Invasive Alien Himalayan Balsam (Impatiens glandulifera Royle)
Investigations were carried out into the allelopathic potential of the invasive alien annual Himalayan Balsam (Impatiens glandulifera Royle) using a series of bioassays, including ones developed or adapted for this study. They were evaluated for their suitability to detect three of the four main modes of allelochemical release, namely leaching, exudation and decomposition. Assays which involved...
متن کاملThe Impact of the Invasive Alien Plant, Impatiens glandulifera, on Pollen Transfer Networks
Biological invasions are a threat to the maintenance of ecological processes, including pollination. Plant-flower visitor networks are traditionally used as a surrogated for pollination at the community level, despite they do not represent the pollination process, which takes place at the stigma of plants where pollen grains are deposited. Here we investigated whether the invasion of the alien ...
متن کاملSeparation and identification of 1,2,4-trihydroxynaphthalene-1-O-glucoside in Impatiens glandulifera Royle.
Methanolic extract from lyophilized roots of Impatiens glandulifera Royle was analyzed by high performance liquid chromatography using DAD and FLD detection and this revealed one dominant highly fluorescent very unstable substance. The stability of this derivative is strongly dependent on the plant material drying procedure and extraction procedure used. The structure of the substance was estab...
متن کاملExtension growth of Impatiens glandulifera at low irradiance: importance of nitrate and potassium accumulation.
BACKGROUND AND AIMS The summer annual Impatiens glandulifera can reach 3 m in height within deciduous woodland. The primary objective was to determine if NO(3)(-) accumulation, and hence its osmotic effect, is an important physiological mechanism allowing Impatiens to achieve substantial height under low irradiance. METHODS Stem extension, concentrations of K(+) and NO(3)(-) in leaves and con...
