Abstract

This study was undertaken to determine whether 2-(3,4-dichlorophenoxy)-triethylamine (DCPTA) improve plant growth of Cd-exposed hemp (Cannabis sativa L.) plants. The results showed that exposure of plants to 50 mg Cd kg 1 soil resulted in an increase in the shoot and root biomass, as well as the root/shoot ratio. These results confirmed that hemp is a Cd-tolerance plant species, and it is possible to culture hemp in Cd contaminated farmlands for bioenergy production. Single application of 10-50 mg L–1 DCPTA increased biomass production in hemp seedlings. When DCPTA and Cd were used simultaneously, they increased the root biomass in a dose-dependent manner. Moreover, DCPTA application caused an increase in root Cd content and the total Cd in the root, and there is a positive correlation between biomass and Cd accumulation in the root.
