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...
Hydrogen cyanamide (CY) has been used to break rest
in temperate crops, but levels used to overcome rest are
sometimes toxic to plants. The rest breaking effect of CY
is thought to involve peroxide metabolism. Inhibition of
catalase by CY has been proposed as a mechanism for
overcoming dormancy in...
Sequence-specific PCR markers were derived from one new and eight previously identified random amplified polymorphic DNA (RAPD) markers for the purpose of identifying grape (Vitis) rootstocks. The markers were developed because the RAPD assay was found to be inconsistent and the original RAPD markers unreliable. Southern hybridization analysis of the...
Fall-sown barley will be increasingly important in the era of climate change due to higher yield potential and efficient use of water resources. Resistance/tolerance to biotic and abiotic stresses will be critical. Low temperature is an abiotic stress of great importance. Resistance to barley stripe rust (incited by Puccinia striifomis...
Collaboration is crucial when advancing in scientific research. One person cannot
study all aspects of a system. That is why it is important for the scientific community to
communicate with each other and stay updated on research being conducted in other labs
around the world. In my research, I was...
Meadowfoam (Limnanthes alba Bentham; Order: Brassicales; Family: Limnanthaceae) is a self-compatible, predominantly allogamous, insect pollinated species. Meadowfoam oil is a source of novel unsaturated very-long-chain (VLC) seed oils (C₂₀ and C₂₂) with low concentrations of saturated fatty acids (typically less than 2%) and outstanding oxidative stability. Here we report the...
Cultivated meadowfoam (Limnanthes alba Benth.) is an annual oil seed crop native to southern Oregon. California and British Columbia. The genus Limnanthes is composed of nine species and divided into two sections, Inflexae and Reflexae. The seed oil of meadowfoam is a rich source of erucic acid and several novel...
The effects of overcoming rest by application of "near-lethal" (NL)
stress treatments on the subsequent development of cold hardiness of
stem tissues of red-osier dogwood, Comus sericea L., at different rest
stages under three post-environments (0°, 23°, and natural condition)
were studied. NL-heat stress (47°C for one hour) treatment during...
