Abscisic acid-enhanced starch accumulation of bioenergy crop duckweed (Spirodela polyrrhiza).

ABSTRACT: To meet the increasing energy consumption around the world and fight global climate change, there is an urgent need to explore renewable energy crops to replace the traditional energy sources. Duckweed (Spirodela polyrrhiza) is widely distributed in the world and has high starch and low lignin contents, which is perhaps an ideal feedstock for bioenergy production. To investigate the effects of abscisic acid (ABA) on duckweed biomass and starch accumulation, Spirodela polyrrhiza was cultivated at different ABA concentrations. The results showed that the highest starch content in duckweed (21.8% dry weight) was achieved in 1.0 × 10^-2 mg L^-1 ABA medium, 70.3% higher than that of the control medium without ABA. The number of starch granules in 1.0 × 10^-
