Abstract

The pollution of environment by toxic heavy metals has increased dramatically over the past decades due to various sources of contamination, mainly industrial and human activities. Soil is the main recipient of air and water contamination. In this study, we evaluated the ability of radish plants to accumulate chromium VI (Cr(VI)) (150 ppm) under the application of citric acid (CA) (15 mM). The results showed that Cr(VI) reduced shoot dry weight, root dry weight, hypocotyl dry weight, and total chlorophyll content. On the other hand, Cr(VI) increased H2O2, malondialdehyde, and antioxidant activities of the radish plant. However, the application of CA improved the growth and physiological parameters and antioxidant content (superoxide dismutase 5 % and 4 %, peroxidase content 24 % and 4.25 %, catalase 38 % and 28 %, and ascorbate peroxidase 4 % and 35 %) in root and shoot part respectively, and increases the accumulation of Cr(VI) in different parts of the radish plant.

外源柠檬酸处理下莴苣提取六价铬的研究

在过去的几十年里，由于各种污染源，主要是工业和人类活动，有毒重金属对环境的污染急剧增加。土壤是空气和水污染的主要接受者。在本研究中，我们评估了在柠檬酸(CA) (15 mM)施用下萝卜植株积累铬VI (Cr(VI)) (150 ppm)的能力。结果表明，Cr(VI)降低了油菜地上部干重、根系干重、下胚轴干重和叶绿素总含量。另一方面，Cr(VI)增加了萝卜植株的H2O2、丙二醛和抗氧化活性。然而，CA的施用提高了萝卜根系和茎部抗氧化剂含量(超氧化物歧化酶含量分别为5%和4%，过氧化物酶含量分别为24%和4.25%，过氧化氢酶含量分别为38%和28%，抗坏血酸过氧化物酶含量分别为4%和35%)和生长生理参数，并增加了萝卜植株各部位Cr(VI)的积累。

期刊介绍： Botanica Pacifica (BP) publishes peer-reviewed, significant research of interest to a wide audience of plant scientists in all areas of plant biology (structure, function, development, diversity, genetics, evolution, systematics), all levels of organization (molecular to ecosystem), and all plant groups and allied organisms (cyanobacteria, fungi, and lichens). BP requires authors to frame their research questions and discuss their results in terms of contemporary problems of plant biology. While the geographic focus of the journal is the Pacific region, research submissions that demonstrate clear linkages with other regions are welcome. BP aims to foster the exchange of research ideas between countries with diverse cultures and languages.
