“…The levels of Zn in the plant material are low and generally in the range of 10-100 mg kg -1 of dry matter. Large parts of agricultural soil are contaminated with zinc by natural and anthropogenic activities including mining and industrial processes and agricultural practices, such as use of fertilizers containing various heavy metals (Staker and Cummings 1941;Lee and Page 1967;Ross 1994;Singla-Pareek et al 2006;Dudka et al 1996). The pollution of soil by zinc has been a major environmental concern (Zarcinas et al 2004).…”

The present study employed a sand culture experiment with three levels of zinc viz., 0.065 (control), 65.0 and 130 mg l -1 Zn (excess) as zinc sulfate, respectively, in sugarcane (Saccharum spp.), cultivar CoLk 8102. The results indicated growth depression, dark green leaves, decreased root number and length and sharp depression in mitotic activity of roots due to high doses of Zn (65 and 130 mg l -1 ); effects were significant at 130 mg l -1 Zn supply. The endogenous ion contents measurements revealed roots to be the major sink for excess Zn with lower amounts in leaves of sugarcane plants. High level of Zn decreased total phosphorus in leaves and increased it in roots. Fe and Cu content decreased, while, Mn increased in sugarcane plants due to high Zn in the growing medium. Plants experienced oxidative stress when exposed to higher levels of zinc. Biochemical investigations indicated high level of hydrogen peroxide, malondialdehyde contents with high chlorophyll a, b and carotenoids contents and activity of superoxide dismutase, catalase and peroxidase enzymes under high Zn conditions. These findings confirm suggest that excess Zn adversely affects root growth and mitotic efficiency, enhances chromosomal aberrations and increases growth and nutrient accumulation abnormalities, as well as oxidative stress.

“…Zinc phytotoxicity in higher plants has been noted by many authors (9,11,14,17,28); many investigators have been able to substantially reduce or eliminate Zn phytotoxicity by simply raising the soil pH if the soil Zn concentrations were not extremely high (8,18,19,27,30). Although pH's above 6.5 reduce the severity of Zn phytotoxicity, injury can still occur on heav-121 ily burdened soils; toxicity problems occurring on calcareous soils and highly contaminated alkaline ore tailings have been described by Robinson et al (25), Boawn and Rasmussen (3), and Brown and Jones (6).…”

Heavy metals in waste materials added to agricultural soils can severely inhibit subsequent crop growth. This study was conducted to evaluate the variation in tolerance among cultivars of an agriculturally important plant species to phytotoxic levels of added soil Zn. Twenty soybean (Glycine max L. Merr.) cultivars were screened, through greenhouse pot studies, for their growth response to Zn at pH 5.5 and 6.5 on a Sassafras sandy loam (Fragiudult) amended with 1.31 (control), 131, and 262 ppm Zn. Significant differential responses were found, and the cultivars were grouped into several tolerance and uptake classes, based on the results of the pH 6.5, 262‐ppm Zn treatment: tolerant (9 to 18% leaf dry weight yield reduction [YR], 5 cultivars), normal (20 to 32% YR, 12 cultivars), sensitive (33 to 48% YR, 3 cultivars); accumulator (696 to 730 ppm trifoliolate leaf Zn, 5 cultivars), normal (549 to 675 ppm Zn, 11 cultivars), and excluder (389 to 540 ppm Zn, 4 cultivars). Soil Zn additions significantly increased root and foliar Mn contents to reported phytotoxic levels at both pH 5.5 and 6.5, but did not influence DTPA‐TEA extractable soil Mn. Significant cultivar differences in root and leaf Mn contents were observed. The results of this work illustrate the importance of cultivar selection, not only for field planting of Zn‐enriched soils, but also for its influence on experimental results.

Sorghum [Sorghum bicolor(L.) Moench] production has increased in the Southeastern United States as a second crop in many double‐cropping systems. Guidelines are needed for Zn concentration in leaf blade tissue for the diagnosis and correction of Zn deficiency and toxicity problems. The Zn critical deficiency level (CDL) and critical toxicity level (CTL) are the minimum and maximum concentrations, respectively, associated with a 10% yield reduction from maximum yield due to Zn deficiency and toxicity. Sorghum was grown in nutrient solutions containing Zn concentrations ranging from 0.0 to 91.78 nmol L−1in 14 increments in the greenhouse. Individual blades were sampled at 49 days growth and analyzed for Zn concentration by atomic absorption spectrometry. The Zn CDL values in blades were 10, 10, 9, 13, and 24 µg g−1for blades 1 (top), 2, 3, 4, and 5 (bottom), respectively, as calculated from the exponential relationship of Zn concentration in blades and top dry weight. The Zn CTL values in blades were 64, 68, 80, 100, and 195 µg g−1in blades 1, 2, 3, 4, and 5, respectively. For tissue sampling to diagnose Zn deficiency and toxicity, blade 1 is recommended. The Zn CDL and CTL are 10 and 64 µg g−1, respectively, sampled at growth stage 2 and near maximum vegetative growth harvested at this time is expected if the Zn concentrations are within the CDL and CTL.
