“…Chromium (VI) is more easily transported inside the plant, as it has been reported to occur by an active mechanism [17]. The initial symptoms of Cr toxicity appeared as severe wilting and chlorosis in Dhatura and Brassica species, as confirmed by [25]. They proposed that chlorosis appeared in the upper leaves of these plants, as an indirect effect of Cr, probably due to the retardation of Fe and Zn translocation.…”

Ghosh -Singh.: Comparative uptake and phytoextraction study of soil induced chromium by accumulator weed species -67 - Abstract. Plant species have been recently used for heavy metal accumulation and most of the studies have been done on hyperaccumulator tolerant species. Metal hyperaccumulator plants though useful to phytoextract metal contaminant from soil, have many shortcomings such as low biomass, edible nature and difficult to harvest. This study is part of a series of studies that attempt to evaluate the phytoextraction potential of commonly found high biomass weed species that are harmless, non-edible in nature. We have investigated and compared five weed species (Ipomoea carnea, Dhatura innoxia, Phragmytes karka Cassia tora and Lantana camara), with two accumulator plants (Brassica juncea and Brassica campestris), in a pot study to assess Cr uptake in the range of 5 to 200 mg kg -1 soil. The results indicated that P. karka showed much greater tolerance to metals than other plants, though the uptake was low. It was more effective at translocating Cr from soil to plant shoot. The order of Cr extraction was I. carnea > D. innoxia > C. tora > P. karka > B. juncea > L. camara > B. campestris. Among the studied plants I.carnea showed maximum chromium extraction and biomass growth, but the difference of shoot by root chromium concentration was least. Other than Lantana camara, all the tested weeds were better for chromium extraction than the accumulator Brassica species. To save the Brassica species infested by army moth, pesticide application was required, whereas weeds required no care.

“…It is known that plants sensitivity to Se is different (Laughli 1993. Turner and Rust (1971) observed wilt of different plants and crop as metal toxicity consequence, but little is known about exact Se(IV) effects to water content in higher plants. Banuelos et al (1997) introduced that roots and shoots DM of Brassica juncea (L.) Czern and Cross, and Brassica carinata cultivars, whose grew in the soil and water with 2 mg Se kg -1 , significantly decreased with increasing Se concentration.…”

Phytotoxicity of Se(IV), Se(VI), Cu and Zn to Sinapis alba L. seedlings was expressed by inhibition of selected physiological processes (root and shoot growth, fresh and dry biomass production, water content) and correlated with their bioaccumulation. Roots growth was inhibited more than that of shoots and only Se(IV) reduced also shoots growth (IC 50 = 25.8 mg L -1 ). Se(VI) decreased more roots (IC 50 = 23.6 mg L -1 ) than shoots growth (IC 50 = 461.4 mg L -1 ). Phytotoxicity to roots growth increased as follows: Zn < Se(VI) ≅ Cu < Se(IV). All metals, except Cu, decreased more roots and shoots fresh mass than that of dry mass. Water content was for all (semi)metals more depressed in shoots, however, for Zn any significant changes in roots WC were confirmed. In any case transportation index Ti overreached value 1 and that indicate metals storage in the roots; however, for control the opposite results were obtained. While the highest bioaccumulation factor (BAF) was determined for Cu in both roots (1.016) and shoots (0.271) the lowest values for this parameter were confirmed for Se(VI) in the roots (0.061) and for Se(IV) in the shoots (0.010). While in the control Cu, Se and Zn content was higher in the shoots, treatment with these metals increased their accumulation mainly in the roots. Statistically negative correlation was confirmed among Se(IV), Se(VI) and Cu accumulation in the roots and water content in the roots, and among Se(IV) and Cu accumulation in the roots and water content in the shoots.

“…Adema and Henzen (1989) Top weight of soybean seedlings grown for 5 d in nutrient solution containing Cr(VI) was reduced 21% by 1 ppm Cr, while 0.5 ppm had no effect (Turner and Rust, 1971). Length of the longest root of rye grass was reduced 69% by exposure to 2.5 ppm Cr(VI) (K Cr O ; 2 2 7 lowest concentration tested) in nutrient solution (pH 7) for 14 d (Wong and Bradshaw, 1982).…”
