Evaluation of the Potential of Duckweed as a Human Food, Bioethanol Production Feedstock, and Antileukaemia Drug

Table 3

Comparisons of the yield, starch yield, and potential bioethanol production between the major bioethanol cereal crops and duckweed.

Parameters	Crops
	Wheat (grain)	Maize (kernel)	Duckweed (whole plant)
Average world yield (t/ha/y)	3.47^a	5.75^a	26.11^#
DW of starch yield (t/ha/y)	2.42^b	4.03^c	13.43^#
Potential yield of bioethanol (L/ha/y)	1552^d	2585^d	8670^#
