plants can ameliorate the negative effects of abiotic stresses. The objective of this study was to (i) investigate gas exchange
(ii )measure oxidant andantioxidant compounds
and (iii) respond how B supply acts on tolerance mechanism to water deficit in young Schizolobium parahyba plants. The experiment employed a factorial that was entirely randomised
with two boron levels (25 and 250 µmol L-1
simulating conditions of sufficient B and high B
respectively) and two water conditions (control and water deficit). Water deficit induced negative modifications on net photosynthetic rate
stomatal conductance and water use efficiency
while B high promoted intensification of the effects on stomatal conductance and water use efficiency. Hydrogen peroxide and electrolyte leakage of both tissues suffered non-significant increases after B high and when applied water deficit. Ascorbate levels presented increases after water deficit and B high to leaf and root. Our results suggested that the tolerance mechanism to water deficit in young Schizolobium parahyba plants is coupled to increases in total glutathione and ascorbate aiming to control the overproduction of hydrogen peroxide and alleviates the negative consequences on electrolyte leakage and gas exchange.
