Boron nutrition and fruit set of 'Italian' prune

Creator:: Hanson, Eric J.
Abstract:: Foliar B sprays have increased fruit set in 'Italian' prune (Prunus domestica L.) by 2 fold in some trials and had no effect in others. This work was conducted to identify reasons for this inconsistent response. Since B levels in flowers are associated with the amount of fruit set, factors...

Sugar uptake, fruit growth and carbon partitioning in the strawberry

Creator:: Forney, Charles F.
Abstract:: Sinks, plant organs which depend on the import of assimilates for growth, play a central role in determining assimilate distribution patterns within the plant. The strawberry fruit is a strong sink for dry matter and its effect on carbon partitioning and assimilation in the plant as well as the mechanism...

Water management effects on birdsfoot trefoil seed production

Creator:: García-Díaz, Carlos Alberto
Abstract:: There is no information available on water management of birdsfoot trefoil grown for seed. Information is also not available describing how to minimize seed losses due to shattering in order to obtain consistently high birdsfoot trefoil seed yields. The objectives of this research are to: (i) quantify crop water use,...

Factors influencing barnyardgrass (Echinochloa crus-galli) control with diclofop

Creator:: West, Lynn Douglas
Abstract:: Diclofop (2- [4 -(2, 4-dichlorophenoxy)phenoxy] propanoic acid), formulated as the methyl ester, selectively kills barnyardgrass [Echinochloa crus -galli (L.) Beauv.] in several crops when applied postemergence. Studies were conducted to determine the effect of soil moisture, barnyardgrass age, and site of exposure on control of barnyardgrass with diclofop. Soil moisture...

Microbial analysis of coniferous forest and nursery soils : effects of ectomycorrhizae, volatiles, and humic-rich organic substrates

Creator:: Schisler, David Albert
Abstract:: Fusarium spp. frequent conifer nursery soils yet are rarely recovered from coniferous forest soils. Experiments were performed to determine what influence humic-rich organic amendments and volatiles from soil, ectomycorrhizal fungi and ectomycorrhizae have on the populations of several physiologic and taxonomic microbial groups potentially related to this phenomenon. A comparative...

Evaluation of allelopathy as a mechanism by which buckwheat suppresses Canada thistle and its mycorrhizae

Creator:: Eskelsen, Steven R.
Abstract:: Experiments were conducted to determine if allelopathy is a mechanism by which buckwheat interferes with a) the growth of Canada thistle and/or b) mycorrhizae colonization in Canada thistle roots. In a competition experiment, buckwheat plant biomass was only affected by the intraspecific competition from other buckwheat plants and not by...

Mechanisms of uptake and some factors influencing the toxicity of 2-chloro-2', 6'-diethyl-N-(methoxymethyl) acetanilide (alachlor) for selected plant species

Creator:: Groenwold, Bareld Egge, 1939-
Abstract:: A number of studies with ¹⁴C-labeled 2-chloro-2', 6'-diethyl- N-(methoxymethyl) acetanilide (alachlor) were conducted to obtain information about the mechanisms of uptake of this herbicide. In other studies, technical alachlor as well as the emulsifiable concentrate formulation of the chemical were used to investigate the effect of several factors on the...

Adaptability of winter wheat cultivars to dryland conditions and their response to water stress

Creator:: Keim, Don Lee
Abstract:: Winter wheat cultivars (Triticum aestivum) were evaluated for their response to water stress and adaptability to a wide range of moisture limited environments. Grain yield was analyzed for ten cultivars at six locations across four years. Regression of the cultivar mean on the year-location mean was used as a measure...
