Capital Deepening and Wage Differentials: Germany vs. US Capital deepening may affect the evolution of the wage differential between skilled and unskilled workers differently in countries with different labor market institutions. If labor market institutions raise the relative wage of unskilled workers in Germany, firms have incentives to invest relatively more into capital equipment complement...

A cytogenetical study on 13 alfalfa (Medicago sativa) cultivars available in Iranian Forest and Rangelands Genebank was performed in order to obtain basic information on the variability in chiasma frequency/distribution, chromosome association and segregation. Such cytogenetic information is useful for planning hybridization programs. Cluster analysis of meiotic data and ordination of cultivars...

Osmotic and oxidative stress responses to iso-osmotic (-0.4 Mpa) NaCl, PEG-6000 and mannitol stress were studied in 15-day old plants of three potato cultivars viz. ‘Kufri Kufri Bahar’ ‘Jyoti’ and ‘Chandramukhi’. After 2-weeks of treatment, plants were analyzed for biochemical and physiological determinants of stress. Relative water content (RWC) and membrane damage rate (MDR) were significantl...

Twelve pumpkin cultivars (Cucurbita maxima D.), cultivated in Iowa, were studied for their seed oil content, fatty acid composition, and tocopherol content. Oil content ranged from 10.9 to 30.9%. Total unsaturated fatty acid content ranged from 73.1 to 80.5%. The predominant fatty acids present were linoleic, oleic, palmitic, and stearic. Significant differences were observed among the cultivar...

because of the importance of iranian rice germplasm and its application in the rice breeding programs and international genetic resources exchanges, some researches are necessary to preserve these valuable genetic resources. for this purpose, the cryopreservation of the biological samples in liquid nitrogen at -196 °c can be used. in this research, the cryopreservation of the zygotic embryos of...

Six chilli cultivars belonging to three species of Capsicum: Capsicum annuum L. (cvs ‘Meiteimorok’ and ‘Haomorok’), Capsicum !utescens L. (cvs ‘Uchithi’ and ‘Mashingkha’) and Capsicum chinense Jacq. (cvs ‘Umorok’ and ‘Chiengpi’) are economically important food crops. !e capsaicin content and pungency in scoville heat unit (SHU) of these six chilli cultivars were determined by high-performance l...

apricot ( armeniaca vulgaris l.) is a popular and an economically profitable fruit of the temperate zone. various apricot genotypes grow in different areas in iran. the genetic diversity of 30 cultivars and genotypes of iranian apricot and as well, of two foreign cultivars (as control) was studied through morphological attributes and rapd markers. in a first experiment, 21 quantitative and qual...

Turkey is very rich in local grape varieties. The solution to the problem of identifying local cultivars, which is considered an important deficiency for the region, will only be possible when they can be defined with molecular markers. Forty-nine local grapevine cultivars from Şanlıurfa (Turkey) were characterized with RAPD markers. Twenty-five decamer primers selected from 60 primers were use...

in this research, the host preference and life cycle of the colorado potato beetle, leptinotarsa decemlineata (say), was studied on 33 potato cultivars. significant difference was observed for all studied traits (p>0.05 & p>0.01). the lowest number of adults was attracted to cultivars raja, carlita and bridget with mean values of 0.33±0.17, 0.50±0.29 and 0.50±0.29 adults, respectively. the lowe...
