Cytotoxic and genotoxic effects of Solanum lycocarpum St.-Hil (Solanaceae) on the cell cycle of Lactuca sativa and Allium cepa

Solanum lycocarpum St.-Hil popularly known as ‘fruta-de-lobo’ or ‘lobeira’ is native to the Brazilian Cerrado, and used in folk medicine due to its phytotherapic properties. The action of S. lycocarpum on the cell cycle and chromosomes in order to demonstrate whether there are aneugenic and/or clastogenic effects is unknown. Thus, this study aimed at investigating the cytotoxic and genotoxic po...

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...

Biological and chemical investigation of Allium cepa L. response to selenium inorganic compounds

The aim of this study was to evaluate the biological and chemical response of Allium cepa L. exposed to inorganic selenium compounds. Besides the investigation of the total content of selenium as well as its chemical speciation, the Allium test was used to evaluate the growth of onion roots and mitotic activity in the roots' meristem. The total content of selenium was determined by inductively ...
