About Jack Dekker

I studied the evolutionary ecology and biology of important weed species:
- Weedy foxtails (Setaria species-group) seed-seedling life history:   Relationship of seed heteroblasty to seedling emergence
- s-triazine resistant Brassica napus:   Evolutionary ecology as pleiotropic chronomutant 
- Chenopodium album (common lambsquarters):   Continental diversity of seedling emergence
- Abutilon theophrasti (velvetleaf):  Growth, development and light competition with soybeans
- Elymus/Agropyron repens (quackgrass):   Rhizome bud dormancy and herbicide translocation
- Experimental-Technical:  World weed seed germplasm collection

Publications herein: Weed Seed Germplasm Collection; Evolutionary Biology of Weeds; Setaria Species-group (foxtails); Chenopodium album (common lambsquarters); Abutilon theophrasti (velvetleaf); Elymus repens (quackgrass); and s-Triazine Resistant Plants
