Four study sites were selected along an altitudinal gradient on Mt. Ashland in the Siskiyou Mountains of southern Oregon. The altitudinal gradient roughly corresponded to a gradient in temperature and water availability ranging from very hot and dry to cool and moist. Air and soil temperatures were continuously measured on...
Reed canarygrass (Phalaris arundinacea L.) is a desirable pasture
grass on wet areas in the Northern United States and Southern Canada,
but it is a serious and troublesome ditchbank weed in the Pacific Northwest
and Rocky Mountain States. The purpose of this study was to learn
more about the development,...
This publication furnishes information that should be useful to 4-H Club leaders and members and other young people. It is intended to supplement subjectmatter material published by the various States and other agencies. The text emphasizes getting acquainted with forest trees and forest stands and learning their different values to...
A series of studies was performed to more clearly evaluate gonadal function in llamas. Luteinizing hormone (LH) and progesterone (P₄) concentrations were compared following natural or hormone-induced ovulation. Luteal regression was evaluated following administration of the prostaglandin F₂α analog cloprostenol. The interaction of age, season and castration on testosterone (T)...
In order to determine the total number of cytochrome P-450 isozymes
present in a given species following various treatments, mature
male rats (Sprague-Dawley) were injected intraperitoneally with the
classic mixed-function oxidase inducers phenobarbital (PB), pregnenolone-
16a-carbonitrile (PCN), 3-methylcholanthrene (3-MC), or the appropriate
control vehicle.
Hepatic microsomes were solubilized and P-450...
Oxidative stress that occurs during cryopreservation may be reduced by the addition of antioxidants. Vitamin E (Vit E), Vitamin C (Vit C), glutathione (GSH), lipoic acid (LA), glycine betaine (GB) and polyvinylpyrrolidone (PVP) were applied at four steps of the PVS2 vitrification protocol (pretreatment, loading, rinsing, and regrowth). Shoot tips...
Hazelnut is one of the most important nuts in worldwide production and the European hazelnut (Corylus avellana L.) is the most economically important of the 11 recognized hazelnut species. Development of new cultivars is continuous, with emphasis on better nut quality, high yield and disease resistance. Hazelnuts are highly heterozygous,...
Corylus avellana L. is a global commodity and a valuable crop for the U.S. Pacific Northwest. A tremendous amount of work has been put into the development of healthy disease free, high yielding and tasty hazelnuts for the in-shell and confectionary markets. Clonal propagation is required to provide nursery trees...

Several aspects of the potent inhibition of bovine plasma amine
oxidase (PAO) by hydrazines were investigated by kinetic and preparative
means. The inhibition was classified as pseudo-irreversible
by the method of Ackerman and Potter (Proc. Soc. Exptl. Biol. Med.
72, 1 (1949), and was found to exhibit Zone B kinetic...
