Differences in Germination, Growth, and Fecundity Characteristics of Dicamba-Fluroxypyr-Resistant and Susceptible Kochia scoparia
The widespread occurrence of herbicide-resistant (HR) Kochia scoparia is an increasing concern for growers in the US Great Plains and Canada. K. scoparia populations resistant to dicamba have been reported in six US states. Populations cross-resistant to dicamba and fluroxypyr have been reported from wheat fields in Montana, USA. It is unclear whether resistance to the auxinic herbicides (dicam...
متن کاملFitness Outcomes Related to Glyphosate Resistance in Kochia (Kochia scoparia): What Life History Stage to Examine?
A fast-spreading weed, kochia (Kochia scoparia), has developed resistance to the widely-used herbicide, glyphosate. Understanding the relationship between the occurrence of glyphosate resistance caused by multiple EPSPS gene copies and kochia fitness may suggest a more effective way of controlling kochia. A study was conducted to assess fitness cost of glyphosate resistance compared to suscepti...
متن کاملNutritional and toxicological evaluations of kochia hay (Kochia scoparia) fed to lambs.
Kochia foliage that had tested positive to Dragendorff's reagent (presumptive alkaloids) and had elicited chronic toxicosis when fed to rats was fed to sheep to characterize early stages of kochia toxicosis and evaluate treatments that might improve tolerance. Twelve fine-wool lambs (46 +/- 9 kg BW) were fed chopped kochia hay (35%) mixed with chopped alfalfa hay (65%) for 4 wk. The kochia diet...
متن کاملاثر تنش شوری بر برخی از خصوصیات فتوسنتزی پنج توده کوشیا (Kochia scoparia (L.) Schrad.)
سابقه و هدف:کارکرد دستگاه فتوسنتزی گیاهان شور دوست قسمت عمده‌ای از تحمل به شوری این گیاهان را به عهده دارد. کوشیا (Kochia scoparia) به عنوان یک گیاه شور دوست در شرایط تنش شوری توانایی تولید زیست توده‌ی، بالایی دارد. مطالعه فتوسنتز و عوامل وابسته به آن در شرایط تنش شوری می‌تواند دیدگاه های فیزیولوژیک مناسبی را در درک رفتار این گیاه در مواجهه با تنش فراهم سازد. بنابراین آزمایش مزرعه‌ای به منظور...
متن کاملevaluation of salinity stress on some photosynthetic characteristics in five kochia (kochia scoparia (l.) schrad.) ecotypes
background and objectives: infunction of the photosynthetic apparatus of halophytes plays an important role in their salinity tolerance. kochia as a halophyte, is of high ability in biomass production in salinity stress conditions. thus study photosynthesis and the related factors salinity stress can provide appropriate physiological view for better understanding of the plant mechanisms of in s...
