Creator:: Maas, E. V. (Eugene Vernon), 1936-
Abstract:: An investigation of Mn uptake by five-day-old excised barley roots revealed that a metabolically-mediated process was involved. In short-term experiments, the rate of Mn absorption was comparable to that of the macronutrient cations. Like other metabolically absorbed cations, the Mn absorption rate was a direct function of the ambient concentration...

Creator:: Mantai, Kenneth Edward
Abstract:: The effects of ultraviolet (UV) irradiation on photosynthesis and various partial reactions involving the individual photoreactions of photosynthesis were examined. These reactions included photo-reduction in adapted green algae, Hill reaction, cyclic photophosphorylation, the 520 nm absorbance change and variable-yield fluorescence. The reactions were measured in spinach chloroplasts and isolated chloroplasts...

Creator:: Rojanasoonthon, Santhad
Abstract:: Nine Gray Podzolic soils from different physiographic regions of Thailand were studied to determine their characteristics and genesis in relation to their parent materials, land form, pedogenic environment, classification and management. The clay was characterized by X-ray diffraction and standard chemical and physical analyses were performed. Mineralogy of the light...

Creator:: Matheron, Michael Earl
Abstract:: A transaminase (aminotransferase, EC 2. 6. 1) was extracted and purified approximately 148-fold from shoot tips of pea (Pisum sativum L. cv. Alaska) seedlings and some properties of the enzyme were determined. The purification included acetone precipitation followed by column chromatography on hydroxylapatite. With a-ketoglutarate as co-substrate, the acetone precipitated...

Creator:: Stevens, Patricia T.
Abstract:: Under defined cultural conditions, large populations of zygotes of the brown algae Fucus vesiculosus L. and F. distichus L. Powell synchronously form a cell wall shortly after fertilization. Intact cell walls, free of cytoplasm and maintaining shape properties of early stages of embryo development, have been isolated from these zygotes....

Creator:: Lopez-Jurado, Gerardo
Abstract:: Field experiments were established in 1982 and 1983 on a Woodburn silt loam soil (Aquultic Argixeroll) to examine the effect of S fertilizer on dinitrogen fixation and dry matter yield of 10 week-old seedling alfalfa (Medicago sativa L. cv. 'Apollo'). Six levels of S fertilizer (0 to 67.2 kg S/ha)...
