Effects of competition on the fitness of wild and crop-wild hybrid sunflower from a diversity of wild populations and crop lines.
Gene flow between crop fields and wild populations often results in hybrids with reduced fitness compared to their wild counterparts due to characteristics imparted by the crop genome. But the specifics of the evolutionary outcome of crop-wild gene flow may depend on context, varying due to local environmental conditions and genetic variation within and among wild populations and among crop lin...
متن کاملstudy on the efficacy of some current herbicides for control of wild oat (avena ludoviciana durieu) biotypes resistant and susceptible to acetyl coa carboxylase (accase) inhibitors
abstract three separate greenhouse experiments were conducted in the greenhouse facilities of the iranian plant protection research institute, tehran, to study the efficacy of some accase inhibiting herbicides for control of resistant based on mechanism, resistance based on enhanced metabolism and susceptible wild oat biotypes. in each experiment, biotypes were treated separately by 17 herbicid...
متن کاملCombining Cultural Practices with Herbicides Reduces Wild Oat (Avena fatua) Seed in the Soil Seed Bank and Improves Barley Yield
A study was initiated in 2001at four locations in western Canada to investigate an integrated approach to managing wild oat, the region’s worst weed. The study examined the effects of combining semidwarf or tall barley cultivars with normal or twice-normal barley seeding rates in either continuous barley or a barley–canola–barley–field pea–barley rotation. Herbicides were applied at 25, 50, and...
متن کاملa comparison of the efficacy of some acetyl coa carboxylase, and acetolactase synthase inhibitor herbicides in control of wild oat (avena ludoviciana)
two separate greenhouse experiments were conducted in the greenhouse of the iranian plant protection research institute, tehran, to compare the efficacy of some acetyl coa carboxylase (accase) and acetolactase synthase (als) inhibiting herbicides in control of wild oat biotypes. in each experiment, populations were independently treated by 10 herbicides each in 12 replications. to evaluate the ...
متن کاملCompetition alters life history and increases the relative fecundity of crop-wild radish hybrids (Raphanus spp.).
The evolutionary impact of crop-to-wild gene flow depends on the fitness of hybrids under natural, competitive conditions. Here, we measured the performance of third-generation (F3) radish hybrids (Raphanus raphanistrum x Raphanus sativus) and weedy R. raphanistrum to understand how competitive interactions affect life history and relative fecundity. Three wild and three F1 crop-wild hybrid rad...
