Growth hormone (GH) has an effect on a broad variety of physiological parameters such as lactation, reproduction, growth and metabolism. Thus, the aim of this study was to detect GH gene polymorphism and its association with breeding values of production and reproduction traits in Raini Cashmere goat. Breeding values were estimated using records on 26731 Raini Cashmere goats. To study GH gene p...

The permanent decline of equipment prices relative to nondurable consumption prices rendered fixed-base quantity indexes obsolete, because of the well-known substitution bias. National Income and Product Accounts (NIPA) responded by switching to a flexible-base quantity index to measure GDP growth. We argue this is a welfare measure of output growth. In a two-sector endogenous growth model, we ...

in order to determine the best traits related to indirect increasing of grain yield, five wheat genotypes (zagros, tajan, durum cul., kohdasht and n-81-18 line) were evaluated by using randomized complete block design (rcbd) with 4 replications in research field of gorgan university of agricultural sciences and natural recourses. the studied traits included leaf area index (lai), crop growth ra...

abstract confused flour beetle, tribolium confusum duval (col.: tenebrionidae) is one of the most important stored product pests of flour in iran. in this research the effects of insect growth regulators (igrs): teflubenzuron, hexaflumuron and pyriproxyfen were studied on larval and imago nutritional indices of confused flour beetle. the results showed that they were more effective on relative ...

use of the growth indices is a method to assessment of intercropping efficiency. in order to evaluation growth indices of soybean, sweet basil and borage in intercropping with different ratios, an experiment base on randomized complete block design was conducted with 9 treatments and 3 replications at north khorasan in 2011. treatments were consisted of the plants pure culture, replacement seri...

the development of seminal and lateral root system plays a major role in plant access to water and nutrients under abiotic stress, especially salinity. in order to understand the relation between root growth responsesand shoot physiological indices oftwo bread wheat cultivars contrasting in salt tolerance (kavir and shiraz), a greenhouse experiment was conducted with two salinity levels (0 and ...
