Table 1 Effects of applications of CaO2 and MgO2 on the SPAD (chlorophyll content), height, and shoot biomass of snap bean with and without flooding in pots, and data were collected two days after flooding, since at that time the flooded plants started wilting.
From: Effects of oxygen fertilization on damage reduction in flooded snap bean (Phaseolus vulgaris L.)
