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....

The metabolic pathways and physiological effects of atrazine in Douglas-fir seedlings

Creator:: Peterson, Charles Adrian
Abstract:: Herbicides are being used as a tool by forest managers to speed the restocking of sites where tree seedlings face competition from grasses for limited moisture, light and nutrients. Retarded growth or, more commonly, death of the seedlings would occur if a selective herbicide was not used to control competing...

The differential response of Fraxinus pennsylvanica, Liquidambar styraciflua, and Acer saccharinum to picloram as measured by CO₂ absorption and evolution

Creator:: Webb, Warren Lewis, 1935-
Abstract:: The tolerance of woody plants to picloram (4amino-3,5,6-trichloropicolinic acid) has been shown by field applications to vary from mild to extreme. A laboratory study was done to investigate the basic causes for this range of tolerance known to exist among three woody plant species, Fraxinus pennsylvanics, March, (green ash) resistant,...

Selective filtering of light by coniferous forests and minimum light energy requirements for regeneration

Creator:: Atzet, Thomas
Abstract:: Spectroradiometric analyses were made to examine the light filtering capacity of coniferous forests and to establish the lower light energy limits for growth of Pseudotsuga menziesii (Mirb. ) Franco, Abies concolor (Gord. and Glend.) Lindi. and Pinus ponderosa Dougi. Visible energy(400-750 nm) was recorded at 48 points under four mixed...

The effects of univalent cations on the inductive formation of nitrate reductase

Creator:: Nitsos, Ronald Eugene
Abstract:: An investigation was undertaken to determine whether potassium is indeed necessary for the in vivo synthesis of a specific protein. The effects of univalent cations on the inductive formation of nitrate reductase and on the level of activity of representative non-adaptive enzyme are presented. Cultures of Neurospora crassa were grown...

The effects of nitrogen, potassium and chloride on nutrient composition in Russet Burbank potatoes (Solanum tuberosum)

Creator:: Murarka, Ishwar P., 1942-
Abstract:: Three greenhouse experiments were designed to measure the effects of N, K and Cl on the nutrient uptake by Russet Burbank potatoes (Solanum tuberosum). A Deschutes sandy loam soil from Powell Butte area in Central Oregon, low in potassium, was used to study these effects. Nitrogen applications produced significant increases...
