energetic cost of leaf construction in the invasive weed Mikania micrantha H.B.K. and its co-occurring species: implications for invasiveness
Construction cost (CC) is a quantifiable measure of energy demand for biomass production and is related to energy-use efficiency. Low construction cost was hypothesized to give invaders a growth advantage by utilizing energy efficiently. The present study examines the energetic cost of leaf construction in the invasive weed Mikania micrantha H.B.K. and its five common co-occurring species (Ager...
متن کاملSeed germination eco-physiology of Mikania micrantha H.B.K
Mikania micrantha H.B.K is an invasive alien weed in South China. To help understand the mechanisms of its invasiveness, we studied its seed germination ecophysiology. We found that the optimal temperatures for seed germination were 25, 30, 15/30°C (night/day), and an ambient temperature (24-32°C). Germination percentage (GP) in dark was less than 10%, and it increased with increasing light int...
متن کاملPhenolics from Mikania micrantha and Their Antioxidant Activity.
A phytochemical study on the aerial parts of Mikania micrantha led to the isolation of two new phenolic compounds, benzyl 5-O-β-d-glucopyranosyl-2,5-dihydroxybenzoate (1) and (7S,8R)-threo-dihydroxydehydrodiconiferyl alcohol 9-acetate (2), together with twelve known compounds, benzyl 2-O-β-d-glucopyranosyl-2,6-dihydroxybenzoate (3), 4-allyl-2,6-dimethoxyphenol glucoside (4), (+)-isolariciresino...
متن کاملAntimicrobial Constituents of the Leaves of Mikania micrantha H. B. K
BACKGROUND To isolate plant-derived compounds with antimicrobial activity from the leaves of Mikania micrantha, to determine the compounds configuration, and to evaluate their antimicrobial activity against eight plant pathogenic fungi (Exserohilum turcicum, Colletotrichum lagenarium, Pseudoperonispora cubensis, Botrytis cirerea, Rhizoctonia solani, Phytophthora parasitica, Fusarium solani, and...
متن کاملInteractive Effect of Herbivory and Competition on the Invasive Plant Mikania micrantha
A considerable number of host-specific biological control agents fail to control invasive plants in the field, and exploring the mechanism underlying this phenomenon is important and helpful for the management of invasive plants. Herbivory and competition are two of the most common biotic stressors encountered by invasive plants in their recipient communities. We predicted that the antagonistic...
