Ipomoea species are troublesome weeds in crop systems through Brazil. Drought stress typically reduces glyphosate efficacy by reducing the foliar uptake of herbicides and their translocation. Using both glyphosate tolerant (GT) and sensitive (GS) plants from Ipomoea grandifolia, I. indivisa and I.

Chemical composition of the slippery epicuticular wax blooms on Macaranga (Euphorbiaceae) ant-plants
Chemoecology, 2000The stems of many Macaranga ant-plants (Euphorbiaceae) are covered by epicuticular wax crystals rendering the surface very slippery for most insects. These wax blooms act as selective barriers protecting the symbiotic ant partners, which are specialized “wax-runners”, against the competition of other ants.

Plants in the genus Nepenthes obtain a substantial nutrient supply by trapping insects in highly modified leaves. A broad zone of the inner surface of these pitchers is densely covered with wax crystals on which most insects lose their footing. This slippery wax surface, capturing prey and preventing its escape from the trap, plays a pivotal role in ...

Epicuticular waxes of two arctic species: Compositional differences in relation to winter snow cover
Phytochemistry, 1995Abstract The leaf wax characteristics of Dryas octopetala and Saxifraga oppositifolia , collected from the high Arctic semi-desert of Svalbard, Norway (79° N, 13° E), were compared and differences in their wax composition related to winter snow cover. The leaf wax composition of the winter-green D. octopetala differed from that of the herbaceous

Effects of environment on the composition of epicuticular wax esters from kale and swede
Phytochemistry, 1997Abstract The composition of intact leaf epicuticular wax esters of two individual genotypes each of kale and swede grown indoors (I) and outdoors (O) at SCRI, Scotland, and outdoors at Wadenswil in Switzerland (S), were determined by GC-mass spectrometry.

Needles of Taxus baccata L. were covered with tubular epicuticular wax crystals varying in diameters (100 and 250 nm) and lengths (300-500 and 500-1000 nm) on the abaxial and adaxial surfaces, respectively. Various sampling protocols were employed to study the chemical composition of the needle waxes on three different levels of spatial resolution ...

Composition of epicuticular waxes from 28 genera of Gramineae: differences between subfamilies
Canadian Journal of Botany, 1981Epicuticular waxes from 34 species in 28 genera in 11 tribes (excluding the Triticeae) in four subfamilies of the Gramineae have been analyzed. Amounts and compositions of hydrocarbons, esters, free alcohols, free acids, and β-diketones were determined.

Surface wax crystals play important roles in protecting plants from pest and disease invasions, and UV irradiation. The wax crystals are less probed individually from the fruit surfaces. Herein the morphologies, chemicals and an efficient method to sample the wax blooms of white wax gourd were addressed. Various crystalloids such as rodlets, platelets,

Chemical composition of epicuticular wax in cabbage plants grown in vitro
Canadian Journal of Botany, 1984The chemical composition of epicuticular wax from cabbage plants grown in vitro was compared with that from plants grown in a greenhouse. There was a greater percentage of polar compounds (fatty acids, primary alcohols, aldehydes, and esters) and less alkanes and secondary alcohols in wax from cultured plants relative to those from greenhouse plants ...
