Floodplains are unique environments that provide a dynamic link between terrestrial and aquatic systems. Intensification of human activity – particularly agriculture urbanisation has resulted in the degradation floodplains worldwide. Restoration sustainable management requires holistic assessment compromise stakeholders to successfully balance environmental, economic, social benefits. Yet, understanding these complex systems sufficiently evidence-based recommendations is challenge. We...
Glyphosate-based herbicide (GBH) applications were reported to induce physiological damages glyphosate-resistant (GR) soybean, which mainly attributed aminomethylphosphonic acid (AMPA). In order study glyphosate and AMPA dynamics in plants associated phytotoxic effects, a greenhouse experiment was set where GR soybeans exposed GBH (0.7 4.5 kg ha–1) sampled over time (2, 7, 14, 28 days after treatment (DAT)). Hydrogen peroxide content increased 2 DAT, while decrease observed for the effective...
Riparian buffer strips (RBS) are encouraged to control agricultural diffuse pollution. In Quebec Province, Canada, a policy promotes 3-m-wide RBS. Abiding farmers minimally maintain herbaceous vegetation, but nutrient retention efficiency could be improved with woody biomass. This work aimed assess if fast-growing willows ( Seemen 'SX64') reduce loads stream, in addition yielding Triplicate treatments of two stem densities and plot were monitored from 2011 2013 randomized block design on...
We investigated the effects of different concentrations glyphosate acid and one its formulations (Roundup) on seed germination two glyphosate-resistant (GR) non-GR variety soybean. As expected, herbicide affected shikimate pathway in seeds but not GR seeds. observed that can disturb mitochondrial electron transport chain, leading to H2O2 accumulation soybean seeds, which was, turn, related lower germination. In addition, showed increased activity antioxidant systems when compared making them...
Since the late 1950’s, Malaysian human population has nearly quadrupled, increasing pressure on natural resource exploitation to meet domestic needs and earn foreign exchange from exports. Global demand for palm oil in particular had steeply increased since mid-1970s by 2013, commodity was leading earner. To fulfill sustain this demand, country’s economy steadily shifted bias towards production associated value addition of products export. However, as a consequence, many Malaysia’s tropical...
The use of glyphosate-based herbicides (GBHs) in industrial agriculture has intensified the past decades, causing a growing concern about occurrence and spatial distribution glyphosate its principal metabolite, aminomethylphosphonic acid (AMPA), environment. In 2014, AMPA content was measured 45 soils from St. Lawrence Lowlands (Quebec, Canada) before seeding at harvest soybean field crops using various weed management practices with or without GBH applications. At same time, recent history...
Abstract Weed management (WM) is necessary to prevent crop losses through competition with weeds and maintain high yields. However, in the case of glyphosate‐tolerant (GT) crops, phytotoxic effects can occur after glyphosate‐based herbicide (GBH) applications, which could impact yields quality. In order assess agronomic performance six WM strategies on GT soybean [ Glycine max (L.) Merr.] maize ( Zea mays L.), field experiments were conducted randomized blocks replicated four times (T 1 :...
Soybean [Glycine max (L.) Merr.] is an important source of health-beneficial compounds, including soyasaponin I. A field study was conducted for 11 yr in Ottawa, ON, Canada, to assess the impacts temperature and precipitation during specific growth stage intervals on I concentration three soybean cultivars. Soyasaponin response air variables were observed at some The complex cultivar specific. Overall, reproductive stages more responsive 20 °C appeared be a critical threshold determining temperature.
L'alpiste roseau ( Phalaris arundinacea L.) est une espèce adaptée au littoral du lac Saint-Pierre. Elle peut être utilisée comme source de fourrage et sa biomasse résiduelle en fin saison par les poissons pour y déposer leurs œufs lors la crue printanière. Une régie plus intensive favorise production fourragère (6974 kg MS/ha), tandis qu'une moins produit des rendements fourrages moindres (2600 MS/ha) mais maximise à l'automne (6271 MS/ha). La favoriser dans le devra tenir compte besoins...
