Determination of Genotoxic Effect of Boron on Allium Cepa Root Meristematic Cells

The effect of boron on the mitotic index of Allium cepa root meristematic cells were investigated. By using the growth inhibition test LD50 value was determined first and then different doses of varied concentrations of boron were introduced to onion tuber roots. Distilled water was used as control. Since Allium cepa cell cycle is 24 hours, application process was carried out at 12, 24 and 48 h...

Genotoxicity of Industrial Paint Effluent on the Root Meristem of Allium Cepa

The genotoxic effects of the industrial effluent from a paint (100%, 50%, 25%, 10%, 5%, 1%, 0.50% and 0.25%) manufacturing company in Ikotun, Lagos was evaluated using the root meristem cells of Allium cepa. chromosomal aberration assays were used to determine the mitotic index and chromosome aberration rate. There was a significant difference (p<0.05) in the average root length of Allium cepa ...

Carbohydrate Content of the Root Tip Cells of Allium Cepa.

Chromosomal aberrations induced by Glycidol in Allium cepa L root meristem cells

Glycidol is used as a stabilizer in the manufacture of vinyl polymers and natural oils and as an intermediate in the synthesis of glycerol, glycidyl ethers, and amines. It is also used as an alkylating agent, demulsifier, and dye-leveling agent and for sterilizing milk of magnesia. Glycidol is an alkylating agent which reacts readily with glutathione; it causes a decrease in glutathione content...
