Increased germination of diverse crop-wild hybrid sunflower seeds.
Gene flow from crop fields to wild populations produces hybrids that often differ from their wild counterparts in growth form, phenology, and life history characteristics. Germination and dormancy dynamics have a strong influence on population persistence, competitive dynamics, and ultimately, plant fitness. They may also play a role in modifying crop gene introgression, which has been of prima...
متن کاملJournal of Crop and Weed
Radiations and radioisotopes are used in agricultural research to induce genetic variability in crop plants to develop improved varieties, to manage insect pests, monitor fate and persistence of pesticides, to study fertilizer use efficiency and plant micronutrient uptake and also to preserve agricultural produce. Use of radiation and radioisotopes in agriculture is one of the most important fi...
متن کاملNitrogen Fertilizer and Crop Residue Effects on Seed Mortality and Germination of Eight Annual Weed Species
Weed seed persistence in the soil seedbank is central to weed population dynamics; however, limited knowledge of mechanisms regulating seed survival in soil remains an obstacle to developing seed-bank management practices. Weed seeds are rich in carbon and nitrogen, and therefore may represent an important nutritional resource to soil microbes. The objective of this study was to test the hypoth...
متن کاملWeeds of agricultural importance: bridging the gap between evolutionary ecology and crop and weed science.
An undeniable and expensive consequence of agricultural practices is the adaptation of weeds to agricultural systems. Weeds are responsible for significant crop yield losses and for financial losses in agricultural production – in the order of 10% per year worldwide (Oerke, 2006). To address this critical problem, the discipline of weed science has expanded over the past 50 yr into an amalgam o...
متن کاملSoftware Tools for Weed Seed Germination Modeling
The next generation of weed seed germination models will need to account for variable soil microclimate conditions. To predict this microclimate environment we have developed a suite of individual tools (models) that can be used in conjunction with the next generation of weed seed germination models. The three tools that will be outlined here are GlobalTempSIM, GlobalRainSIM, and the soil tempe...
