The Effect Of Two Growth Retardant Chemicals, Cycocel And B-Nine, On Certain Nitrogeneous Components In Barley Seedlings, Linda Kinser

Masters Theses & Specialist Projects

Certain chemicals are known to inhibit growth in many plant species. These chemicals possess a common trait, the ability to inhibit stem elongation by suppressing the activity of the subapical meristematic region (11). These growth retardants have been extensively studied during the past several years in an effort to determine the biochemical mechanism responsible for reduction in plant height. The characteristic effect of these chemical retardants on the growth pattern has been described as producing plants with shorter, thicker stems and broader, darker green leaves. Tolbert, however, noted that although plants treated with the plant growth retardant, Cycocel, (2-chloroethyltrimethlammoniumchloride) and …

A Statistical Study Of Sex Ratio Data From A Sample Of Students At Western Kentucky University, Robert Loyd

Masters Theses & Specialist Projects

Information on family size, sex ratio, and sex by order of birth was obtained from a sample of students at Western Kentucky University during the 1968-69 school year. Participants were white Americans coming primarily from Central Kentucky.

Data were obtained on the immediate, maternal, and paternal families from 1,018 students. Sex ratios for the immediate and parental generations were 101.2 and 103.3, respectively. The overall sex ratio for the study was 102.7. These ratios did not differ significantly from he reported secondary sex ratio of 106 in the United States.

Correlation coefficients were computed between the sexes of various children …
