Fig. 2From: Tea plant roots respond to aluminum-induced mineral nutrient imbalances by transcriptional regulation of multiple cation and anion transportersEffects of Al stress on the metal content in roots of hydroponically grown tea plants. Metal element accumulation (Mg, Fe, Zn, Mn, Cu and Cd) in roots of two-year-old tea seedlings grown hydroponically in SK medium containing 0.4 mM Al, and exposed to a series of Al concentrations (0, 0.4, 2.5 mM Al) for different times, then measured by ICP-MS. Data are presented as means ± SD from three independent experiments and statistical significance is based on Student’s t-test (*P < 0.05; ** P < 0.001) compared with controlsBack to article page
