Cytogenetic effects of⁹⁹technetium on meristematic cells of root tips ofVicia fabaL. andstatistical comparison

Abstract

In this study, cytogenetic effects of 99 technetium (99 Tc) on meristematic cells of root tips belonging to Vicia faba L. have been investigated. Seeds of the plant were prepared and kept in 99 Tc standard for different time periods: 1/12, 1/4, 1/2, 1, 2, 3, 4, 5, 6 and 12 h. Seeds treated with 99 Tc were sprouted and the root tips obtained were prepared for microscopic examination. Some abnormalities e.g. chromosome breaking, chromosome dispersion, bridge chromosomes, chromosome adherence and ring chromosomes were observed. Abnormalities seen for each treatment depended on the time period. The variety and number of abnormalities usually increased with increased treatment time. The results obtained were evaluated statistically.

Uranium Sources, Uptake, Translocation in the soil-plant System and Its Toxicity in Plants and Humans: A Critical Review

“…Furthermore, it leads to chromosomal cell defects 133 . According to a study conducted on the Vicia faba a decrease in the mitotic index has been observed on the root tip cell 134 . It was found that uranium adversely affected the germination rate and seedling growth, and the level of toxicity depends upon the physiological state and selective permeation of different metal ions through tissues surrounding the embryo and hence determines the toxicity.…”

Mathematical evaluation of chromosomal anomalies induced by xylol in Vicia faba L. regarding application time and concentration

“…The type and severity of health effects depends on several factors, including the amount of xylol you are exposed to and the exposure time (Vijayakumar, 2015). In the literature, some researchers made investigations on cytogenetic effects of especially heavy metal pollution on plants and other living things (Shraideh, 2010;Özdemir et al, 2015;Şutan et al, 2018;Osama et al, 2020;Tengjaroenkul & Neeratanaphan, 2020). In the literature, the studies on the effects of solvents on plants have mostly been evaluated in terms of agricultural productivity (Barchan et al, 2014;Ghasemzadeh et al, 2011).…”
