“…Taraxacum officinale is a good indicator of environmental pollution and is often used as a biomonitor because it is an abundant, widely distributed plant, and the leaves and roots accumulate metals, including As, Br, Cd, Co, Cu, Cr, Hg, Mn, Pb, Sb, Se and Zn (Kuleff and Djingova 1984;Djingova et al 1986;Simon et al 1996). Recently it was used to evaluate trace metal bioavailability in abandoned industrial sites, community gardens and parks in urban Montréal, QC (Marr et al 1999).…”

is a perennial weed occurring in parks, gardens, pastures, orchards, roadsides, vegetable gardens, agricultural crops and horticultural crops. A common weed worldwide, it was originally introduced from Eurasia and now occurs in every province of Canada. It is an aesthetic problem during flowering and seed production, interrupting turfgrass uniformity and density; it reduces yields of agricultural crops; it causes slower drying of hay; its pollen is allergenic; and it acts as an alternative host for several pests and diseases. A number of herbicides are available for its control. Mechanical removal of T. officinale plants has limited success, due to the regenerative capacity of the long taproot. Insects, fungi, sheep and geese have been considered as biological control agents for dandelion.

“…However, in order to compare concentrations from different land use areas, a plant that is ubiquitous in nature, like a weed species, must be tested. The concentration of many metals including Cd, Cu, Mn, Pb and Zn in the leaves of Taraxacum officinale Weber (dandelion) has been correlated with local environmental pollution in previous studies (Djingova et al 1986;Kabata-Pendias and Dudka 1991).…”

, W. 1999. Trace metals in Montreal urban soils and the leaves of Taraxacum officinale. Can. J. Soil Sci. 79: 385-387. Uptake of Cu, Zn, Mn, Pb, and Cd by Taraxacum officinale Weber (dandelion) growing on abandoned industrial sites, community gardens and parks in urban Montreal was measured to evaluate trace metal bioavailability. Total soil trace metal concentrations exceeded the Canadian remediation levels only in the industrial sites, but tissue concentrations at all land use types were normal. Multiple regression analysis suggests that available PO 4 may reduce uptake of Cu and Zn. It is evident that sites classified as contaminated on the basis of total soil metal may have low levels of bioavailability.

“…(1 suggested by Djingova and Kuleff (1986). For Na concentration, Djingova et al (1993) suggested the background level for dandelion harvested in spring during the blossoming period is about 150 mg g dm (1 , whereas our values for most biotypes in June were less than 100 mg g dm (1 .…”

“…P content was usually lowest in biotypes 711A and 231L, and Ca content was usually lower in biotypes 711H and 231A than in the other biotypes. In 2006, there was a trend for several elements of the lowest The concentrations of most elements were within the background levels or concentrations observed in areas that had not been contaminated by industrial activity (Djingova and Kuleff 1986;Bergen et al 1990; KabataPendias and Dudka 1991; Keane et al 2001). For example, Cd concentrations in 2006, 1 yr after dandelion plants were placed in the field, ranged from 0.74 to 1.13 mg g dm…”

The objectives of this study were to determine whether different leaf shapes are due to genotypic differences, whether chemical composition varies with leaf shape, and whether plants vary in their response to glyphosate. Plants with possible glyphosate tolerance were collected in 1998 from a pasture field where forage grasses were terminated with glyphosate, and from an alfalfa (Medicago sativa L.) field where no herbicides had been applied. Image analysis of plants that were progeny of the original collection indicated that they have significantly different leaf shapes. DNA analysis confirmed that genotypic differences associated with leaf shape exist among dandelion plants collected at the Lethbridge Research Centre. The biotypes had different metal concentrations, which may be a concern if plants are sampled to monitor metal contamination. All biotypes had acceptable metal concentrations for use as cattle feed. In greenhouse tests, all biotypes required similar doses of glyphosate to reduce growth by 50%. All biotypes have considerable tolerance to glyphosate at rates to at least 1.8 kg a.e. ha(1 , root fragments remained that were capable of supporting new leaf growth.
