Biochemical Basis for Plant CompetitionA survey has been made of the literature on biochemical characteristics of plants with particular emphasis on factors affecting photosynthesis. From these characteristics, plants have been divided into two groups, efficient and non-efficient. This division is justified on the basis of data published by numerous workers. A hypothesis has been developed that efficient plants often have been ... ... hiện toàn bộ

Interactions of Herbicides with Photosynthetic Electron TransportThe two primary sites of herbicide action in photosynthetic electron transport are the inhibition of photosystem II (PS II) electron transport and diversion of electron flow through photosystem I (PS I). PS II electron transport inhibitors bind to the D1 protein of the PS II reaction center, thus blocking electron transfer to plastoquinone. Inhibition of PS II electron transport prevents t... ... hiện toàn bộ

Weed Survey System used in Saskatchewan for Cereal and Oilseed CropsA weed survey system methodology was developed and used annually for 4 yr in the province of Saskatchewan. Based on a stratified random sampling procedure, fields were selected in wheat (Triticum aestivum L.), barley (Hordeum vulgare L.), oat (Avena sativa L.), rye (Secale cereale L.), r... ... hiện toàn bộ

Nitrogen fertilizer timing and application method affect weed growth and competition with spring wheatManaging crop fertilization may be an important component of integrated weed management systems that protect crop yield and reduce weed populations over time. A field study was conducted to determine the effects of various timings and application methods of nitrogen (N) fertilizer on weed growth and spring wheat yield. Nitrogen fertilizer was applied the previous fall (October) or at plant... ... hiện toàn bộ

The Herbicide Saflufenacil (Kixor™) is a New Inhibitor of Protoporphyrinogen IX Oxidase ActivitySaflufenacil (Kixor™) is a new herbicide of the pyrimidinedione chemical class for preplant burndown and selective preemergence dicot weed control in multiple crops, including corn. In this study, the mode of action of saflufenacil was investigated. For initial characterization, a series of biotests was used in a physionomics approach for comprehensive physiological profiling of saflufenac... ... hiện toàn bộ

Using Assembly Theory to Explain Changes in a Weed Flora in Response to Agricultural IntensificationThe intensification of crop management in the U.K. over the past 60 years has resulted in the decline of the populations of a number of annual plant species adapted to arable habitats. In contrast, other species continue to be common as arable weeds. A community assembly approach was taken to explain these recent changes in the weed flora using databases of plant functional traits, a pot e... ... hiện toàn bộ

Use of Ecophysiological Models for Crop-Weed Interference: Relations Amongst Weed Density, Relative Time of Weed Emergence, Relative Leaf Area, and Yield LossThe performance of a mechanistic simulation model of crop-weed competition was evaluated with data on the effects of weed density, relative time of weed emergence, and environmental conditions on crop yield for three different crop-weed combinations. Reductions in crop yields due to weed competition were simulated accurately for all experiments, except for one case in which severe water st... ... hiện toàn bộ
