Growth in herbaceous perennials

Creator:: Nakajima, Rie
Abstract:: Several studies of herbaceous perennials have addressed the effects of environmental factors during and after production, inherent cold hardiness, and post-harvest handling procedures to enhance flowering and growth during establishment. The regrowth of both woody and herbaceous forage plants following establishment is reported to be directly related to reserve-nitrogen content....

The Effects of Nitrate and a Pathogenic Fungus, Batrachochytrium dendrobatidis, on Amphibians

Creator:: Negru, Delia
Abstract:: The current rate of global biodiversity loss and extinctions is unparalleled and a major concern. Freshwater organisms are facing particularly rapid rates of biodiversity loss. Amphibians, which require an aquatic environment for part of their life cycle, are one of the most vulnerable vertebrate groups. Amphibians are experiencing population declines,...

Molecular basis of target-site resistance to acetolactate synthase-inhibiting herbicides in mayweed chamomile (Anthemis cotula L.)

Creator:: Intanon, Suphannika
Abstract:: Mayweed chamomile (Anthemis cotula L.) is an annual weed in the Asteraceae family that is commonly found in fields of the Pacific Northwest. Acetolactate synthase (ALS)-inhibiting herbicides are frequently used to control a broad spectrum of weed species including mayweed chamomile. Seeds of four biotypes of mayweed chamomile (KJ, KL1,...

Nitrogen use and management in red raspberry

Creator:: Rempel, Hannah Gascho
Abstract:: The effects of ¹⁵N-labeled fertilizer applied to mature summer-bearing red raspberry (Rubus idaeus L.) plants were measured over two years. Four nitrogen (N) treatments were applied singularly at 0, 40, or 80 kg·ha⁻¹ of N in early spring (budbreak), or split with 40 kg·ha⁻¹ of N (unlabeled) applied at budbreak...

The effects of water and shade treatments on photosynthesis and root-rhizosphere respiration in young ponderosa pine

Creator:: Johnson, Theresa J.
Abstract:: Water treatments were applied to young ponderosa pine trees in the Eastern Cascades, Oregon during the 2003 growing season, and shade treatments were applied during the 2003 and 2004 growing seasons to understand how photosynthesis and soil respiration, particularly the root/rhizosphere fraction (R[subscript rrh]), would respond to increased moisture availability...

Experimental and numerical modeling of wave height attenuation by emergent coastal vegetation

Creator:: Blackmar, Philip James
Abstract:: Coastal vegetation dampens waves which can provide benefits to the local area, but existing literature shows large variations in the degree of wave height attenuation depending on plant properties and wave conditions. Better knowledge of how to predict the wave height decay accurately in different types of vegetation may help...

Monitoring for Ozone Injury in West Coast (Oregon, Washington, California) Forests in 1998

Creator:: Campbell, Sally J., Smith, Gretchen, Temple, Pat, Pronos, John, Rochefort, Regina, and Andersen, Chris
Abstract:: In 1998, forest vegetation was monitored for ozone injury on permanent plots in two Sierra Nevada national forests in California, at three locations in Mount Rainier National Park in Washington, and at 68 forest health monitoring (FHM) locations throughout Washington, Oregon, and California. This was the first year that extensive...

Overexpression of antioxidant genes in transgenic tomato tolerant against multiple stresses

Creator:: Wang, Yueju
Abstract:: The effect of increased manganese superoxide dismutase (Mn-SOD) and cytosolic ascorbate peroxidase (cAPX) on various abiotic stresses was studied using transgenic tomato (Lycopersicon esculentum) plants. Transformants were selected in vitro based on kanamycin resistance, confirmed by PCR and northern blot analyses. Northern blots showed an enhanced gene expression of Mn-SOD...

Comparison of the water relations characteristics of woody plants in western Oregon

Creator:: Davis, Kent J.
Abstract:: I studied the water relations traits, twig conductivity, C'3 isotopic composition, and wood density of three conifer and five angiosperm species in western Oregon. This study took place from spring 2002 to fall 2003 on four sites. Species were selected to represent the diversity of drought tolerance of woody plants...

Hydrological consequences of two native shrubs in semi-arid Senegal : patterns, processes, concepts and methods

Creator:: Kizito, Fred
Abstract:: Water availability is a critical limiting element in semi-arid ecosystem productivity and presents particular challenges in Sahelian countries such as Senegal. The landscapes are characterized by the presence of two common semi-arid shrubs (Piliostigma reticulatum and Guiera senegalensis), both of which may be important hydraulic regulators in these water-limited ecosystems....
