ETRAPLOID perennial teosinte, Zea psrennis (Hitchc. ) Reeves and ManTgelsd. is the only close relative of the annual Zea, including maize and 2n teosinte, that has the ability to regrow after producing seed. The other Zea, like most annuals, die during seed maturation. The tetraploid form retains totipotency in basal axillary buds and branches throughout the period when the older culms produce ...

Apple (Malus×domestica Borkh.) is the fourth fruit in importance and Iran ranks fifth in apple production in the world. Longevity of juvenility in apple extends breeding cycles and makes its breeding a tough job. To alleviate this barrier via genetic engineering, the genes involved in flowering and floral development of apple and their function must be identified and characterized. Most of thes...

the purpose of this research is to evaluate the effectiveness of implementation quality management system (iso 9001:2000) in gas processing plants of national iranian gas company using balanced scorecard approach. more specifically, we chose the balanced scorecard framework to examine five well-known gas processing plants in national iranian gas company from four different perspectives in order...

UNLABELLED The age structure of human populations is exceptional among animal species. Unlike with most species, human juvenility is extremely extended, and death is not coincident with the end of the reproductive period. We examine the age structure of early humans with models that reveal an extraordinary balance of human fertility and mortality. We hypothesize that the age structure of early ...

this research investigate the potential of rhizobium leguminosarum b.v .phaseoli to improve growth and nutritional status of common bean (akhtar cultivar) at three levels of salinity of s0, s1 and s2 (0, 35 and 70 mm sodium chloride, or 0, 3 and 6 ds/m, respectively). the greenhouse experiment was conducted as a factorial design in randomized completely with three replications by using the ster...
