mechanisms of drought stress tolerance of gf677 rootstock, peach and almond hybrid, (prunus persica × prunus amygdalus) were studied under in vitro conditions. plantlets of gf677 rootstock were subcultured into the murashige and skoog (ms) solid proliferation medium containing 1 mg/l ba (6-benzyladenine) and 0.1 mg/l naa (naphthaline acetic acid) in four drought stress levels 0 (control), 10, 2...

background and objectives: over the last two decades, a large number of researches have been conducted regarding the importance of nitrogen in sugar beet. this indicate that there were needs to investigate more on nitrogen management to achive higher production and quality because less nitrogen application result in reducing yield and high nitrogen application would increase production costs an...

security policy-making in critical regions is one of the main concerns of the research centers and academic institutes. security-building in the regions like the caucasus is important because the historical roots of conflict could be seen in the policies of various countries. whenever some manifestations of authoritarianism can be seen, some countries are in the state of cooperative action. how...
