Urinary metabolites of brominated fatty acids - identification and kinetics in rats

Creator:

Sotillo, Vidal Eliezer

Resource Type:

Masters Thesis
Chemically induced male sterility and natural out-crossing in selected wheat cultivars (Triticum aestivum L. em Thell)

Creator:

Ekse, Ali Osman

Abstract:

Three chemicals SD 55446, SD 55447 and WL 84245 were found to induce male sterility in cultivars of wheat or triticale. Both SD 55446 and SD 55447 when applied at a concentration of 0.896 kg/ha resulted in 90% male sterility. However, SD 55447 caused female sterility at the same concentration...

Masters Thesis
Time and duration of growth stages and subsequent grain yield in selected wheat cultivars (Triticum aestivum L. em Thell)

Creator:

Choi, Byung Han

Abstract:

The need to develop a shorter life cycle wheat cultivar which would be more adapted to multiple cropping systems prompted this study. Thus the following information was obtained. Greatest variations in developmental patterns were found in the stem elongation, booting, inflorescence emergence and anthesis for five winter and five spring...

Masters Thesis
Role of inoculum sources of Botrytis cinerea in the epidemiology of gray mold of snap beans

Creator:

Johnson, Kenneth Bjorn

Abstract:

Spore dispersal gradients and pod disease gradients from point inoculum sources of Botrytis cinerea were measured over time in two snap bean field experiments. Laboratory grown inoculum was placed at ground level in a 30 x 30 cm square at bloom initiation and removed at full bloom. Dispersal of inoculum,...

Masters Thesis
Possible association between dwarfing genes Rht₁ and Rht₂ and the reaction to Septoria tritici blotch in winter wheat (Triticum aestivum L. em Thell)

Creator:

Baltazar, Baltazar

Abstract:

Four isogenic lines possessing different combinations of height reducing genes Rht₁ and Rht₂ from 'Norin 10' were crossed to a short stature, early maturing, septoria susceptible cultivar identified as the 'Tibet Dwarf'. The isogenic lines originated from the backcross population of 'Itana'/3/'Norin 10'/'Brevor 14'//6*'Itana'. Parents, F₁ and F₂ generations provided...

Masters Thesis
Duration and rate of the grain filling period and subsequent grain yield in crosses between facultative and winter wheat cultivars (Triticum aestivum L. em Thell)

Creator:

Mou, Beiquan

Abstract:

Concerns about the genetic control and environmental influence of various stages of development including the grain filling period, and the relationship between early maturity and grain yield prompted this study. The experimental material consisted of two facultative and two winter wheat cultivars. A dial!el cross, excluding reciprocals, was also developed...

Masters Thesis
Potential of Trichoderma sp. for inhibition of Botrytis cinerea and Sclerotinia sclerotiorum on snap beans

Creator:

Nelson, Mark E.

Abstract:

Isolates of Trichoderma spp. collected from snap bean foliage were tested for inhibition of grey mold of snap beans caused by Botrytis cinerea. In a detached blossom-pod assay an isolate of Trichoderma hamatum reduced pod rot by 94% compared to the nontreated check. Control was comparable to that obtained with...

Masters Thesis
Durum wheat quality and its relation to electrophoretic banding patterns

Creator:

Encinas-Mungarro, Andrés

Abstract:

Physical properties of gluten and pigment content are of primary importance in determining quality in durum wheat (Triticum turqidum L. var. durum). The objective of this investigation was to evaluate the contribution of different -y-gliadin protein subunits in durum wheat pasta quality as measured by the sodium dodecyl sulphate microsedimentation...

Masters Thesis
Utilization of non protein nitrogen by rabbits

Creator:

Mathius, I-Wayan

Abstract:

Several studies have been conducted to examine the utilization of non-protein nitrogen by the New Zealand White rabbit. Soybean meal (SBM) or urea added to a low protein (13% CP) diet and a positive control diet were fed to does and their offspring during a nine month experiment. Urea and...

Masters Thesis
Possible association between grain protein content and yield as influenced by harvest index and biological yield in selected hard red winter wheat (Triticum aestivum L.) crosses

Creator:

Costa, José María

Abstract:

Grain yield and grain protein are often negatively associated in wheat. When yield increases and grain protein decreases, there can be an adverse effect on the milling and baking quality if the desired end product is bread flour. It has been suggested that this inverse association is the result of...
