Thrips tabaci Lind. (Thysanoptera: Thripidae) is a key pest of onions worldwide. It causes both direct and indirect damage to onion crops, resulting in high yield losses. Today, the Integrated System Production Plant Protection requires growers use onion- thrips-resistant cultivars. has become apparent that improvement existing cultivars may not be sufficient, so it necessary search for desirab...

Rhodanese is the major detoxifying enzyme for cyanide and requires sulphur for its action. Allium cepa (Onion) is rich in organosulphur which may serve as an antidote for cyanide poisoning by supplying sulphur to the enzyme rhodanese. The possible effects of Allium cepa on rhodanese activity during cyanide toxicity was investigated in male Wistar rats. Sixty Wistar rats (150-180 g) were divided...

Introduction: It has been reported that garlic (Allium sativum) and onion (Allium cepa) are used all over the world in different diseases, such as infections, injuries, gastrointestinal dysfunctions and cardiovascular diseases. Therefore, our aim in this work was to study the ability of garlic and onion oils to offset the infectivity as well as the metabolic disturbances induced by Schistosoma ...

The problem of the localization of intranucleolar DNA in root meristematic cells of Allium cepa has been investigated under both light and electron microscopy following formaldehyde fixation coupled with deoxyribonuclease extraction. The observations reveal that most, if not all, of the intranucleolar DNA is located inside small lacunar spaces confined to the fibrillar regions of the nucleolar ...
