Exogenous and endogenous factors related to seed germination and vigor in certain varieties of sugarbeet Beta vulgaris L.

Creator:: Kim, Syng Chul
Abstract:: Studies were conducted on the causes of low germination of monogerm sugarbeet seed grown in western Oregon. Emphasis was placed on the identification and measurement of endogenous inhibitors as related to the germination and vigor. Both qualitative and quantitative analytical methods were applied to examine the organic substances in the...

Physiological effects, distribution and metabolism of dimethyl sulfoxide in DMSO treated seed potato tubers (Solanum tuberosum L.)

Creator:: Dimalla, Gerard George
Resource Type:: Dissertation
Full Text:: more but smaller tubers; conse- quently, DMSO could aid in controlling growth in varieties which re

Growth and reproductive development in selected cultivars of Kentucky bluegrass given different durations of exposure to floral inductive conditions

Creator:: Turner, J. Kevin
Abstract:: Kentucky bluegrass (Poa pratensis L.) cultivars are known to differ quantitatively in their photothermal floral inductive requirements. The extent to which these requirements are met influences the potential for subsequent panicle exsertion. A better understanding of the inductive requirements as they vary among cultivars would aid in the selection and...

Nitrate reductase activity and inheritance of grain protein in six barley cultivars (Hordeum vulgare L. and Hordeum distichum)

Creator:: Samphantharak, Krisda
Resource Type:: Dissertation
Full Text:: . (1962) found that grain protein content in a population of plants within a 12 given variety varied

Genetic variability and association between agronomic and quality characteristics in twenty-nine female genotypes of Humulus lupulus L.

Creator:: Roberts, Donald Day
Abstract:: The genetic variability in and association between 14 traits that affect maturity, yield, and chemical properties of its product. The plant characters measured were: vigor, flowering date, harvest date, yield, lateral length, nodes per lateral, cones per lateral, cones per vine, cone weight. Alpha-acid and beta-acid content of the cone,...

CER and leaf characteristics of four tall fescue (Festuca arundinacea Schreb.) selections differing in forage yield

Creator:: Cohen, Cynthia Joy
Abstract:: Gas exchange, leaf area development, leaf anatomy and stomatal characteristics of four tall fescue selections differing in forage yield were examined to provide further insight into characteristics associated with yield differences of these selections. Winter-growing TFM 26 and TFM 16, the highest and lowest-yielding selections, respectively, and summer-growing selections TFK...

Chemical and genetic evaluation of high lysine and protein in selected barley crosses

Creator:: Helm, James Henry, 1944-
Abstract:: Four agronomically and genetically diverse spring barleys were used in a crossing program to study the inheritance of lysine in barley and to determine its possible association with certain agronomic and morphological characters. The cultivar Hiproly was used as the source of high protein and lysine. Characters measured included plant...

Combining ability and associations of agronomic traits involving three sources of dwarfism in wheat (Triticum aestivum, L. em Thell)

Creator:: Maya de Leon, Jose Luis
Abstract:: Three genetically different dwarf cultivars of spring wheat were evaluated as potential sources of short stature to use in a wheat improvement program. The study involved a five parent diallel cross which included a semidwarf, a standard height and three dwarf cultivars. The genetic sources of dwarfism included a Norma...

Compensating effects and gene action estimates for the components of grain yield in winter wheat (Triticum aestivum, L. em Thell)

Creator:: Abi-Antoun, Michel
Abstract:: Five winter wheat cultivars and their diallel crosses were evaluated for plant height, harvest index, deading-maturity duration, the components of yield, (spikes per plant, spikelets per spike, kernel weight and kernels per spikelet)and total plant yield. Two diverse locations, Moro, a dryland site (250 mm annually) located in central Oregon...

Seed development and germination of monogerm sugar beets (Beta vulgaris L.) as affected by maturity

Creator:: TeKrony, Dennis M.
Abstract:: Maturation rates of monogerm sugar beet seed grown in Western Oregon were measured quantitatively to determine attainment of maximum seed development and germination. Seed was collected at various intervals after anthesis from two hybrid varieties representing the extremes in resistance (hard bolting) and susceptibility (easy bolting) to seedstalk development. The...
