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...

Factors associated with the implementation fidelity of a school-based social and character development program : findings from the Positive Action program, Hawai’i

Creator:: Beets, Michael W.
Abstract:: Implementation fidelity (dosage, adherence, quality of delivery, responsiveness, program differentiation) is the degree to which a program was carried out to its original intent. The following three studies examined the implementation fidelity of a school-based health promotion social and character development (SACD) program. The, Positive Action (PA) program was a...

Classification errors in the analysis of fourfold tables

Creator:: Abdullah, Mohammed Abusaleh
Abstract:: Misclassification introduced by fallible measurements affects the estimate of the proportion in a class as well as the comparison of proportions in different classes. In this thesis the magnitude of effects of misclassification and the importance of misclassification error rates on estimates of proportions and variances of these estimates were...

Floret fertility and seed yield in selected perennial ryegrass cultivars as affected by time and rate of nitrogen (N) application

Creator:: Gangi, Ali Salih
Abstract:: To increase efficiency of seed production, it is important to understand the effects of nitrogen (N) fertilizer rate and time of application. In particular, the effects on floret fertility should be examined since only a small proportion of florets actually produce harvestable seed. For these reasons, experiments were conducted in...

Pollination biology and pollinator alternatives in mermaid meadowfoam (Limnanthes alba Hartw. ex Benth.)

Creator:: Jahns, Thomas R.
Abstract:: Meadowfoam (cultivar Mermaid) is an entomophilous winter annual oilseed crop that has historically produced an average of only two of five seeds per flower. Reference to inadequate meadowfoam pollination exists in the literature, but quantitative evidence is lacking. Studies were undertaken to: 1) quantify meadowfoam pollination requirements and 2) evaluate...

Interrelationships of Meloidogyne hapla Chitwood, 1949 with Heterodera schachtii Schmidt, 1871 on Beta vulgaris L.

Creator:: Jatala, Parviz
Abstract:: Self-interactions (effects of reinoculation with the same nematode) in Meloidogyne hapla and Heterodera schachtii on Beta vulpris at different levels of inocula with various population combinations were studied. In M. hapla, the only significant increase of galls was noted in treatments when 250+250 larvae were inoculated at 10-day intervals. Longevity...
