Despite an extensive history of research into herbicide resistance in New Zealand maize, some aspects remain understudied. Herbicide was first detected the 1980s maize crops, with atrazine Chenopodium album L. and Persicaria maculosa Gray. Since then, has also developed to dicamba, last five years Digitaria sanguinalis (L.) Scop. populations have been reported be resistant nicosulfuron. Here we...

Sunflower is the most important oil crop in Republic of Croatia. In last two decades, it has been grown on average 33,506 ha with a grain yield 2.66 t/ha. Weeds represent one causes biotic stress, and their action reflected competition for nutrients, water, light space. The weed flora sunflower crops Croatia extremely diverse, we will often meet: Polygonum persicaria L., lapathifolium Ambrosia ...

The experiments were conducted in 2017-2018 on soybean (Glycine max L.) three climatic regions of Russia (Altai Region, Krasnodar Region and Astrakhan Region) to evaluate efficacy herbicide diclosulam (WG, 750 g/kg). Treatments included diclosulam: 1) applied preemergence (PRE) - 18.75 37.5 g i.a. ha-1; 2) postemergence (POST) at 1-3 leaves soybeans (BBCH 11-13) 11.25 22.5 ha-1. Monocotyledonou...

Quercetin 3-O-beta-(2(")-galloyl)-rhamnopyranoside (QGR) is a naturally occurring quercitrin gallate, which is a polyphenolic compound that was originally isolated from Persicaria lapathifolia (Polygonaceae). QGR has been shown to have an inhibitory effect on nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated macrophage RAW 264.7 cells. Therefore, this study was conducted to in...

Interspecific hybridization followed by polyploidization appears to have played a major role in plant diversification, but quantifying the contribution of this mechanism to diversification within taxonomically complex clades remains difficult. Incongruence among gene trees can provide critical insights, especially when combined with data on chromosome numbers, morphology, and geography. To furt...
