This study investigates aberrations caused by barium and vanadium on meristematic cells of Lens culinaris Medik. Barium and vanadium ions at various concentrations (0.05 M, 0.1 M, 0.25 M, 0.5 M, and 1.0 M) were exposed to the seeds of the plant at fixed time interval (12 h). After seedlings, with a microscopic examination images were captured about the root tips. Those images showed that several abnormalities occurred on the plant such as chromosome breakings, chromosome dispersion, bridge chromosome, chromosome adherence, ring chromosome. Variety and number of abnormalities were counted and compared to each other statistically. The results show an increase in abnormalities caused by for both ions with increasing treatment time. Chromosome adherence and chromosome breaking have reverse relationship in which number of occurrence for one of them decreases with increase on other one. Fish bone and chromosome adherence have a positive relationship in which number of one increases with the raise in other's number. Exposed metals have caused formation of ligands with proteins which can prevent the persistence of metal ions in DNA protein cross-links that are involved in DNA formation process.

的新视角的像差引起的钡和钒离子扁豆Medik

这项研究调查了钡和钒引起的晶状体分生组织细胞的像差梅迪克 以固定的时间间隔(12小时)将各种浓度(0.05 M,0.1 M,0.25 M,0.5 M和1.0 M)的钡和钒离子暴露于植物种子。幼苗后,用显微镜检查捕获有关根尖的图像。这些图像表明植物​​上发生了一些异常,例如染色体断裂,染色体分散,桥染色体,染色体依从性,环染色体。对异常的种类和数量进行计数,并进行统计学比较。结果表明,随着处理时间的增加,由两种离子引起的异常增加。染色体依从性和染色体断裂具有相反的关系,其中一种发生的次数随着另一种发生的增加而减少。鱼骨与染色体的依从性呈正相关,其中一个的数量随另一个的数量的增加而增加。暴露的金属导致与蛋白质形成配体,从而可以防止金属离子在DNA形成过程中涉及的DNA蛋白质交联中持续存在。
