Aims We investigate the effect of position within a size-structured population on the reproductive allocation (RA) and flowering probability of individual plants of Sinapis arvensis. We also assess the effects of plant size and changing level of CO2 on both responses. Methods Sinapis arvensis L., (field mustard), an annual agricultural weed, was grown in monoculture at six densities under ambie...

Wild mustard (Sinapis arvensis L.) and milk thistle (Silybum marianum (L.) Gaertn.) are two competitive broad-leaved weeds commonly found in cereals Europe, while several weed species have developed resistance to the main herbicides that applied on these crops. Thus, implementation of integrated management (IWM) programs is great importance. Field experiments were conducted based a split-plot d...

to evaluate the competition between wheat and wild mustard (sinapis arvensis) in nitrogen and herbicide levels, an experiment was conducted in ramin agriculture and natural resources university, at 2007-8. a split-plots design in rcbd (randomized complete blocks design) with three replications was used for this experiment. the nitrogen levels (0, 60, 120 and 180kg/ha) arranged in main plots. ea...

over the past 20 years since tribenuron-methyl herbicide registration in iran, reports of erratic control of broadleaf weeds with it have increased in wheat fields of aq qala. in order to evaluate the incidence of resistance in wild mustard (sinapis arvensis) and turnipweed (rapistrum rugosum) to tribenuron-methyl herbicide, dose-response assays were conducted during the years 1390 and 1391 at ...

Introduction Yellow mustard (Sinapis alba L.) is a new multipurpose rotation oilseed crop for Willamette Valley agriculturalists, especially non-irrigated operations. Yellow mustard can also be used to produce condiment mustard, as a green manure crop, and as a biopesticide. Although yellow mustard seed production is relatively new to the Willamette Valley, Oregon’s north-central counties have ...

abstract in order to study the effect of various densities of wild mustard (sinapis arvensis l.) on growth indices of canola (brassica napus l.) in climate of molathani, ahvaz, an experiment was conducted in the experimental field of ramin agricultural and natural resources university, in 2006-2007. the split-plot set of treatments was arranged within randomized complete block design with four ...

Under controlled-environment conditions, ethametsulfuron-methyl doses that inhibited growth by 50% (ED(50)) were >100 and <1 g of active ingredient (ai) ha(-)(1) for ethametsulfuron-methyl-resistant (R) and -susceptible (S) wild mustard, respectively. There were no differences between the two biotypes with regard to absorption and translocation of the herbicide. Three days after treatment, appr...

Biotypes of the broad-leaved wild mustard (Sinapis arvensis L.) found in wheat fields of Aegean and Marmara region of Turkey were characterized and shown to have developed resistance to sulfonylurea (chlorsulfuron), an inhibitor of acetolactate synthase (ALS). DNA sequence analysis of the ALS genes from two such resistant ("R") biotypes, KNF-R1 and KNF-R2, revealed point mutations, CCT (Pro 197...
