Environmental influences on monoterpenes and phenolics of Mentha piperita

Creator:: Yao, Cheng C.
Abstract:: Vegetatively propagated peppermint (Mentha piperita L., cv. Black Mitcham) was used to determine the effects of night temperatures (8°C vs 25°C) on the plant growth in terms of fresh weight and leaf area, and on metabolite contents. The plants were sampled after 14 days, 21 days and 28 days in...

A biochemical investigation of the nitrogenase system from soybean root nodules

Creator:: Koch, Burton Lee
Abstract:: The primary purpose of this investigation was to determine the conditions necessary for the preparation of cell-free extracts of nodule bacteroids capable of catalysing the reduction of acetylene to ethylene and nitrogen to ammonia. Initial investigations were conducted to determine whether intact soybean root nodules would reduce acetylene to ethylene...

Propionate metabolism and its relationship to leghemoglobin biosynthesis in soybean nodules

Creator:: Jackson, Earl Kenneth
Abstract:: Experiments are reported which demonstrate that a cobalt deficiency in R. meliloti results in a decreased cytochrome content of bacterial cells. It is concluded that the effect of cobalt deficiency on cytochrome content of Rhizobium cells and on the leghemoglobin content of nodules possibly may be explained by an effect...

Some properties of ribonucleotide reductase in Rhizobium species

Creator:: Cowles, Joe Richard, 1941-
Abstract:: Ribonucleotide reductase from Rhizobium meliloti has been partially purified and characterized. The enzymatic reduction of ribonucleotides to deoxyribonucleotides is dependent upon B₁₂ coenzyme and dihydrolipoate. B₁₂ coenzyme was more effective than B₁₂ coenzyme analogues in the reductase reaction. The affinity of the R. meliloti reductase system for B₁₂ coenzyme was...

Correlations between horticultural characteristics and Fusarium root-rot resistance in Phaseolus vulgaris L.

Creator:: Wang, Theodora
Abstract:: To study the association between Fusarium root-rot resistance (Fusarium solani f. sp. phaseoli) and economically inportant characteristics of beans, 2259 lines each consisting of 30 plants were used. The lines were randomly selected for root-rot reaction, but were selected for differences in vigor and differences in plant and seed pigments,...

Comparative gibberellin relationships in tall and dwarf peas (Pisum sativum L.)

Creator:: Anderson, James David
Abstract:: Experiments were performed to determine whether a direct correlation exists between the growth rates of tall and dwarf peas grown either in the light or in the dark and endogenous gibberellin (GA) content. Three separate but related experimental approaches were utilized: (1) the determination of possible qualitative and /or quantitative...

The biology and control of reed canarygrass (Phalaris arundinacea L.) on irrigation ditchbanks

Creator:: Comes, R. D. (Richard Durward), 1931-
Abstract:: 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,...

Physiology of ripening in pears

Creator:: Wang, Chien Yi
Abstract:: Investigations were conducted to study in detail some biochemical and physiological aspects of ripening in pears. Anjou pears picked at different degrees of maturity were treated with Ethrel (2-chloroethane phosphonic acid), 4000 ppm, and ethylene, 500 ppm, for different lengths of time. Respiration rate was measured twice daily and changes...

Response of strawberry plants to manganese nutrition

Creator:: Sabharwal, Sudarshan Lal
Abstract:: The effects of manganese nutrition on growth, mineral composition, carbohydrate and nitrogen metabolism, IAA oxidase and phenols of 'Northwest' strawberry plants are reported. Growth and mineral composition response were investigated in sand culture and Hoagland's solution 2 modified to contain 0.0, 0.5, 2.5, 12.5, 25.0, 62.5 and 125.0 ppm substrate...
