Cytological changes in Trigonella Foenum-graecum (l.) Under the Cadmium Stress

Abstract

The experiment was carried out to the study of cytological change in Trigonella foenum-graecum under the cadmium stress. Different kind of chromosomal abnormalities like chromosome fragment, ring chromosome, micronuclei, vagrant chromosome, C-metaphase etc. were observed during cytological studies. The mitotic index was frequently reduced and percentage of aberrant cells increase due to the concentrations of cadmium was increase and finally plant growth reduced.

Response of fenugreek (Trigonella foenum-graecum L.) seedlings under moisture and heavy metal stress with special reference to antioxidant system

“…However, once stress is set, stress tolerance responses preserve cell organelles and tissue structures (Kramer, 1983). The decreased mitotic index is attributed by the formation of aberrant cells and the result is very much similar with Patel and Patel (2013) in the same crop fenugreek with cadmium stress. The increased activity of antioxidant enzymes such as SOD and POD are found to occur during stress (Shah et al, 2001;Diaz et al, 2005), to resist oxidative damage leading to adaptation and survival of plants during periods of stress (Malecka et al, 2001).…”
