Water-soluble chitosan and phytoremediation efficiency of two <i>Brassica napus</i> L. cultivars in cadmium-contaminated farmland soils
<p>Pot and field trials were conducted to investigate Cd uptake and phytoremediation efficiency of two <i>Brassica napus</i> cultivars (QY-1 and SYH) with applied water-soluble chitosan (WSC, Pot: 0, 2% and 4%; Field: 0 and 10 g·m<sup>−2</sup>) grown in Cd-contaminated soils. The results from the pot and field trials generally showed that WSC treatments significantly increased Cd concentrations in shoot and root tissues by 33.77–159.71% (except for SYH/JY) and 7.42–168.71% of two <i>B. napus</i> cultivars compared with the control (<i>p</i> < 0.05). The uptake of Cd by shoots of SYH was obviously higher than by shoots of QY-1 treated with WSC under pot and field conditions, which was 1.54–2.22 times than that of QY-1 (<i>p</i> < 0.05). The results indicated that 2% WSC treatment significantly increased the water-soluble and acid extractable Cd in rhizosphere soils of both <i>B. napus</i> cultivars. Furthermore, Cd concentrations in the oils of two <i>B. napus</i> cultivars with applied WSC (10 g·m<sup>−2</sup>) grown under field conditions were not significantly different from commercial rapeseed oils. Rapeseed oil of <i>B. napus</i> is not only an edible oil with high nutritional value, but it can also be converted into biomass diesel that can be used as a substitute for petroleum diesel.</p>
