Diversity and abundance of insect pollinators on Allium cepa L

Field experiment was conducted at CCS Haryana Agricultural University, Hisar during 2009-10 to investigate the diversity and abundance of insect pollinators on Allium cepa L. and correlate their incidence in relation to the abiotic environmental factors. Hymenopterans were found to be the most abundant (60%) followed by Lepidoptera, Diptera and Coleoptera. Variation in abundance was recorded ov...

Antioxidant and Phytobiological Studies on Two Allium Cepa L. Extracts.

AIM To investigate the antioxidant potential of two Allium cepa L. extracts. MATERIAL AND METHODS The antioxidant activity of the two extracts (encoded EC1 and EC2) was assessed using two methods: DPPH (2,2-diphenyl-1-picrylhydrazyl) scavenging capacity and determination of their reducing power; phytobiological, studies were performed using grains of Triticum aestivum L., Falmura variety. R...

Antibacterial Activity of Mature and Green Allium Cepa

Antibacterial in vitro activity of white (bulb), red (bulb) and spring (bulb and leafs) onion towards the Gramnegative Escherichia coli 8752 and the Gram-positive Bacillus subtilis 8751 was investigated. Mature onion samples were purchased from a big supermarket while the green onion was organically grown. Experiments were performed via agar well diffusion method. Samples were separately homoge...

Sensitivity of Allium cepa and Vicia faba towards cadmium toxicity

Sensitivity of common onion (Allium cepa L.) and faba bean (Vicia faba L.) to cadmium (Cd) stress was investigated using genotoxicity endpoints. Simultaneously, the antioxidative stress enzymes (guaiacol peroxidise and catalase) and lipid peroxidation [malonaldehyde (MDA) content] were investigated in the plants exposed to Cd in solution. The endpoints screened for genotoxicity included chromos...
