Plants were treated with either 0 mm (control) or 1 mm methyl jasmonate (MeJA).
Elemental absorption (μg per leaf)=(elemental concentration in the treated half – elemental concentration in the control half) × dry weight of the treated half of the leaf.
Values are the mean ± SD (n = 6).
Where P < 0·05 occurred between control and 1 mM MeJA for each species is indicated with different lower case letters.
