The effects of cadmium on the nitrogen fixation system in Alnus rubra

Creator:: Wickliff, Carlos
Abstract:: Alnus rubra (Bong. ) seedlings were grown in sand culture and irrigated with nutrient solution containing CdCl₂ ranging from 5 μg to 100 mg per liter. Treatment of A. rubra seedlings for 4 weeks with 50 and 100 mg CdCl₂ per liter of nitrogen-free nutrient solution decreased in situ nitrogenase...

Yield, quality characteristics, and composition of Limnanthes alba seed as affected by rate, source, and date of nitrogen application

Creator:: Ayres, Thomas Arthur
Abstract:: The effect of nitrogen (N) application on seed yield of Limnanthes alba was studied for two years at two locations. Seeding following alfalfa (Medicago sativa L.) was compared to establishment after wheat (Triticum aestivum L.). Treatments used were a control (no N applied), and two rates of N (50 and...

Some effects of sulfur fertilization on the nutrient value of subclover-grass forage

Creator:: McCarthy, Michael J.
Abstract:: Pastures consisting of mixtures of subclover (Trifolium subterraneum) and grasses have responded to sulfur fertilization on many sites in Douglas County, Oregon. The objectives of this study were to examine specific changes in forage quality which occur as sulfur is applied in excess of the amount required for maximum yield...

Aluminum toxicity studies in rice (Oryza sativa L.)

Creator:: Martinez-Racines, Cesar P.
Abstract:: A nutrient solution technique developed for wheat was used to determine tolerance of rice cultivars to aluminum (Al) toxicity. Pre-germinated rice seed was placed on top of a screen and allowed to grow on the Al-free solution for 72-96 hours or until the primary root was 2-3 cms long. Seedlings...

Sethoxydim herbicide in red fescue and bentgrass : levels and mechanisms of selectivity

Creator:: Butler, J. Hugh B.
Abstract:: The herbicide rate required to reduce growth by 50% (GR₅₀) of 11 cultivars of red fesue (Festuca rubra L. and F. rubra ssp. commutata) and for four cultivars of bentgrass (Agrostis tenuis Sibth. and A. stolonifera L. var. palustris) to sethoxydim (2-[1-(ethoxyimino) butyl]-5-[2-(ethylthio)propyl]-3-hydroxy-2-cyclohexen-1-one) was determined in greenhouse and laboratory experiments....

Nitrate reductase activity as a factor influencing the seasonal succession of marine phytoplankton

Creator:: Roelofs, Nancy Ann
Abstract:: Nitrate reductase is known to be the enzyme regulating the reduction of nitrate to nitrite in plants. This reduction is the first and rate-limiting step in the transformation of inorganic nitrate to a cellular nitrogen form. Since this reduction process is essential to phytoplankton growth when nitrate is the only...

The effects of light on photosynthesis and rooting of leafy cuttings of Pisum sativum L.

Creator:: Davis, Tim D.
Abstract:: The effects of light incident on leafy cuttings is quite complex because' light influences several factors which may affect root formation. One effect of light is to influence the carbohydrate status of the cutting by influencing photosynthesis. The role of current photosynthate in the rooting of leafy cuttings is uncertain....
