  • Models of a four-species annual weed community : growth, competition, and community dynamics

    Creator:
    Roush, Mary Lynn
    Abstract:
    Models of weed communities aid in the development of weed management strategies and elucidate the processes and mechanisms that regulate plant populations and communities. A conceptual weed community model was developed to organize key regulatory life-history processes. Specific investigations focused on the processes of plant growth and competition, and relationships...

  • The effects of density and proportion on spring wheat and Lolium multiflorum Lam

    Creator:
    Concannon, Julie Ann
    Abstract:
    This thesis consists of four chapters. Literature is reviewed in Chapter 1. Chapter 2 describes an addition series experiment to determine the influence of species density and proportion on vegetative and reproductive yield of spring wheat and Lolium multiflorum. Chapter 3 consists of a growth analysis experiment to determine whether...

  • The population dynamics and growth of salmonberry (Rubus spectabilis) and thimbleberry (Rubus parviflorus)

    Creator:
    Maxwell, Bruce D.
    Abstract:
    Salmonberry (Rubus spectabilis) and thimbleberry (Rubus parviflorus) are clonal shrub species common to reforestation sites in the Oregon Coast Range. These species have economic importance, because they reduce conifer seedling growth and survival. A population modeling approach was used to facilitate study of the biology of these species and to...

  • Dinitroaniline-herbicide resistance in goosegrass (Eleusine indica) : ecophysiological aspects

    Creator:
    Valverde, Bernal E.
    Abstract:
    Growth of individual goosegrass (Eleusine indica (L) Gaertn.) plants of three dinitroaniline-herbicide resistant (R) and three susceptible (S) biotypes from North Carolina, South Carolina, and Mississippi was analyzed in greenhouse experiments. Leaf area and biomass measurements, including root, shoot, above-ground, and total dry weights were similar among the biotypes studied....
