A foundational study assessed effects of biochemical pathway introduction into poplar to produce eugenol, chavicol, p-anol, isoeugenol and their sequestered storage products, from potentially available substrates, coniferyl and p-coumaryl alcohols. At the onset, it was unknown whether significant carbon flux to monolignols vs. other phenylpropanoid (acetate) pathway metabolites would be kinetic...

Background Amaranthus hybridus, a common agricultural weed in Brazil, has been associated with complications the management of major crops. Recently, A. hybridus biotypes suspected resistance to herbicide glyphosate have observed state Paraná. Objective To characterize glyphosate-resistant biotypes. Methods Three independent experiments were conducted evaluate four hybridus. Twelve doses applie...

abstract in order to determine the critical period of weed control in euro-flour variety of sunflower (helianthus annus, l.) an experimental was conducted with a randomized complete block design with 10 treatments and three replications in islamic azad university astara-branch-agricultural college in 2006 growing season. experimental treatments were conducted in two sets, the first set included...

introduction:the prevalence of atopic diseases has increased in recent decades dramatically. the most common aeroallergens in northeastern iran have not been fully defined. define the most common aeroallergens in allergic patients based on the skin prick test (spt) was aimed in this investigation.materials and methods:this cross-sectional study enrolled 1,006 allergic patients (aged 1–86 years)...

the performance of different yield loss models from an exponential family was evaluated in safflower-redroot pigweed systems in two field experiments conducted during 2007 and 2008 growing seasons at the research field of agricultural college of shiraz university, iran. the yield loss of safflower was recorded as relative yield loss in experimental plots laid out in split plot design with three...

introduction this study was intended to evaluate the nutritional value, phenolic compounds and digestibility coefficients of barberry leaves. berberis vulgaris is one of the major crops in the province. the province has more than 70 percent and 95 percent of the total area under cultivation of barberry. waste and foliage of barberry harvest traditionally used to feed livestock tannin concentrat...

Estimation of coherent and incoherent radio frequency (RF) signal attenuation through foliage is of great importance for a number of radar and communication problems. At UHF band and higher frequencies foliage presents a complex environment for electromagnetic waves in terms of scattering and wave propagation. For most applications, dealing with complex foliage models that account for single an...

Gas exchange was measured on a pruned Pinus radiata D. Don hedge and on a long-branch P. radiata tree near Hamilton, New Zealand, in spring 1993 when soil water content was close to field capacity. Foliage at the end of long branches (9.0 m) showed a marked drop in net photosynthetic rate and stomatal conductance as the saturation deficit increased, whereas foliage on short branches (0.5 m) sho...

We investigated how host plant phenology and plant species affected longevity, reproduction, and feeding behavior of an invasive weevil. Phyllobius oblongus L. (Coleoptera: Curculionidae) is common in northern hardwood forests of the Great Lakes Region. Adults emerge in spring, feed on foliage of woody understory plants, and oviposit in the soil. Preliminary data indicate that adults often fee...
