Stem-unit measurements could be useful for early selection if these dimensions were highly heritable and strongly correlated with traits of commercial interest, such as height growth. Height increments and the number and length of stem segments were mesured in the first and second growth period in predetermined and free growth of Douglas-fir seedlings from 40 families in each of 2 populations from southwestern Oregon. Populations, or families in populations, exhibited genetic variation in all traits except number of stem units in predetermined growth. Heritabilities for stem-unit measurements were higher than those for height increment in the first growing season, but not in the second. Correlations among measurements of stem units and height increments were only moderate (generally <0.70). Stem units are not likely to be better measurements of height in early selection of Douglas-fir than are measurements of either predetermined or free growth.

The relationship between carbon dioxide, crop and food production index in Ghana: By estimating the long-run elasticities and variance decomposition Sarkodie, Samuel Asumadu; Owusu, Phebe Asantewaa (2017-06-01) The study estimated the relationship between carbon dioxide, crop and livestock production index in Ghana: Estimating the long-run elasticities and variance decomposition by employing a time series data spanning from 1960-2013 using both fit regression and ARDL models. There was evidence of a long-run equilibrium relationship between carbon dioxide emissions, crop production index and livestock production index. Evidence from the study shows that a 1% increase in crop production index will increase carbon d...
Correlated responses of height increment and components of increment in 2 year old Douglas fir Kaya, Zeki; Admas, WT (Canadian Science Publishing, 1989-09-01) The consequences for growth and phenology of early selection for height or its growth components were evaluated in 160 open-pollinated families of Douglas-fir (Pseudotsugamenziesii (Mirb.) Franco) from southwestern Oregon. Seedlings from two inland and two coastal populations (40 families each) were grown for two growing seasons in a common garden. Predicted response to selection suggests that risk of low juvenile–mature correlation and maladaptation with early selection would be less in the inland than in ...
The decay rho(0) -> pi(0)pi(0)gamma and the role of sigma-meson Gokalp, A; Yılmaz, Osman (2001-05-24) We study the radiative decay p(0) --> pi (0)pi (0)gamma within the framework of a phenomenological approach in which the contributions of sigma -meson and omega -meson intermediate states and of the pion-loops are considered. We conclude that the sigma -meson amplitude makes a substantial contribution.
Genetic and physiology of cold and drought resistance in Turkish red pine (Pinus brutia, Ten.) populations from southern Turkey Kandemir, Gaye Eren; Kaya, Zeki; Önde, Sertaç; Department of Biology (2002) The purpose of the study was to determine the pattern of genetic variation in morphological and physiological traits associated with cold and drought stress using seedling from over-exploited and natural populations of Pinus brutia Ten. (Turkish red pine) from southern Turkey. To determine the pattern of genetic variation existing in over-exploited and natural populations, seedlings from 6 populations each with 40 families were raised in Ankara forest nursery from 1998-2000. Three of the populations (Yaylaa...
Genetic diversity of sheep breeds focusing on conservation research in turkey Açan, Sinan Can; Togan, İnci Zehra; Öktem, Hüseyin Avni; Department of Biology (2012) In the first part of the present study, samples of 13 native Turkish sheep breeds (n=628) were examined, individually and comparatively, with respect to their 19 microsatellite loci to characterize them by employing various statistical analyses. Low FST values, high mean number of alleles and allelic richness as well as results of Factorial Correspondence Analysis and Structure analyses showed the degree of admixture between native sheep breeds of Turkey, IVE and SAK were observed as the most distincts of t...
