ABSTRACT: An experiment conducted at the University of Baghdad, College of Agriculture during 2014-2015 by Germination ofseeds ofwheat in the stimulation ofgeneticvariationsin three-variety wheat abo greab, ebaa, Iraq. The variables were the extract of(Citrullus Colocynthis) fruits at concentrations (0.0, 50.0, 100.0, 150.0, and 200.0) mL.L-1. PCR-RAPD test and detection PCR-RAPD test in differences presence in band number and weights in the extract of(Citrullus Colocynthis) fruits treatment and control treatment inlight of the resultscan be concluded that the extract of(Citrullus Colocynthis) fruits the ability tomake ageneticvariationsinwheat and recommends isolating thesubstance responsiblefor causingthesevariationsand diagnosis.

Keywords: The extract of(Citrullus Colocynthis) fruits, PCR-RAPD.

ABSTRACT: Maize is very important crop which is mainly used for food and human consumptions as well as wide adaptation to biotic and abiotic stress such as drought , heat , diseases and insects tolerant .It's can be used to stabile yield under growing conditions change when exposed it to extreme droughtstress. This is very big problem for maize genotypes, especially in tropics and subtropics areas. This study has been designed and carry out in greenhouse of university Texas A&M, USA to investigate the effects of three period of irrigation on DHN1gene expression and increasing of the drought tolerance in maize genotypes under this study. The chlorophyll content trait shown higher more than others genotypes in the Pioneer31B13 (52.23 ,46.02 and 41.11) respectively for three periods of irrigation...............

ABSTRACT: Characters of skin lesions of camels due to ticks' infestation were evaluated in abattoirs of Sammawah city of Iraq. Out of 30 camels inspected before slaughter, 10 skin specimens had no complication of scratching related to tick biting were processed for microscopical examination. Grossly the tick bite lesions showed congestion and swelling. The microscopic feature at skin attachment sites of ticks were congestion of the blood vessels of dermal plexuses and extensive haemorrhage in dermis with chronic inflammatory cellular response.
