Weedy Setaria Seed Life History
The nature of weeds is a complex adaptive, soil-seed communication system. The nature of weedy Setaria life history is an adaptable, changeable system in which complex behaviors emerge when self-similar plant components self-organize into functional traits possessing biological information about spatial structure and temporal behavior. The nature of the weedy Setaria is revealed in the physical...
متن کاملFitness correlates of crop transgene flow into weedy populations: a case study of weedy rice in China and other examples
Whether transgene flow from crops to cross-compatible weedy relatives will result in negative environmental consequences has been the topic of discussion for decades. An important component of environmental risk assessment depends on whether an introgressed transgene is associated with a fitness change in weedy populations. Several crop-weed pairs have received experimental attention. Perhaps, ...
متن کاملFunctional Trait Differences between Weedy and Non-weedy Plants in Southern California
Weedy plants may have unique functional traits that distinguish them from other species. We categorized four annual plant species as weedy and five as non-weedy based on their prevalence in disturbed and invaded environments. This designation was tested in a field trial where we scattered equal numbers of viable seeds in 20 different plots and monitored density and cover over three months. The ...
متن کاملInheritance of Seed Dormancy in Weedy Rice
should provide new insight into seed dormancy and resistance to preharvest sprouting. Seed dormancy contributes to the adaptability of plants in nature Rice germplasm (Oryza spp.) varies in degree of seed and is of considerable importance in agriculture. The weedy rice dormancy (Roberts, 1961a; Wu, 1978; Oka, 1988, p. 87– (Oryza sativa L.) strains LD, SS18-2, and TKN12-2 and cultivar ‘N22’ 123;...
متن کاملAphids Limit Fecundity of a Weedy Annual (raphanus Sativus)1
Few previous studies document effects of herbivores on the reproduction of wild plants in situ. We examined the impact of aphids' on seed production in wild radish (Raphanus sativus L.), an annual herb. Aphid infestation increased during the three-month flowering period. Flower and fruit production declined during the season, in part due to aphids. Inflorescences of lateblooming plants more tha...
