Abstract

The shortage of water is extremely severe in China and the situation is growing worse because of the water pollution by heavy metal ions which is difficult to be removed with conventional methods. The precipitation of heavy metal ions makes the elimination even more difficult. Hydrocharis dubia (Bl.) grown in 1/2 Hoagland growth medium with different Cu2+ concentrations is studied to explore its utility in eliminating Cu2+ by investigating the effects of Cu2+ on the biomass gain and photosynthesis of Hydrocharis dubia (Bl.). The amounts of Chlorophyll a and b within the leaves, net photosynthetic rate, stomatal conductance, intercellular CO2 concentration and transpiration rate are also investigated. The biomass gain decreases with increasing Cu2+ concentration and negative gain occurs in Hydrocharis dubia (Bl.) grown in the medium with p(Cu2+)=5.0mg·L-1. The amounts of Chlorophyll a and b undergo decreasing with increasing Cu2+ concentration as well, indicating the synthesis of Chlorophyll is impaired by Cu2+ due to the effects of Cu2+ on the growth of Hydrocharis dubia (Bl.) which results in the decreasing of the net photosynthetic rate and stomatal conductance.
