Table 1.

Total plant dry weight and leaf dry weight of cucumber plants at the end of experiment. Plants were treated with excess Cu (Cu), excess Cu and Si supply (Cu + Si), excess Cu and additional Fe supply (Cu + Fe), or combined excess Cu and additional Fe and Si supply (Cu + Fe + Si); control plants (C) remained untreated.

Treatment	Dry Biomass (g Plant−1)
	Total	Leaf
C	0.330 ± 0.050 c	0.223 ± 0.035 b
Cu	0.209 ± 0.047 a	0.160 ± 0.005 a
Cu + Si	0.265 ± 0.021 b	0.199 ± 0.014 b
Cu + Fe	0.291 ± 0.005 bc	0.200 ± 0.006 b
Cu + Fe + Si	0.305 ± 0.008 bc	0.217 ± 0.008 b 1

¹ The values are means of four replicates ± SD. Different letters indicate significant differences among the treatments at p < 0.05.
