Calcium partially relieves the deleterius effects of hypoxia on a maize cultivar selected for waterlogging tolerance

| description |
Low soil oxygen concentrations due to waterlogging or transient flooding
severely reduce maize production. However, genotypes with tolerance or even resistance
to hypoxia develop morphological and biochemical adaptation mechanisms which may
prove to be useful criteria for the selection and breeding of new improved genotypes.
The objective of this work was to evaluate the effect of levels and modes of application
of calcium sources on biomass yield, the contents of total soluble sugars and reduced
sugars and on the activities of invertase isoforms and phosphoenolpyruvate carboxylase,
in a maize variety (BRS 4154) derived from the 14th selection cycle for tolerance to
transient soil flooding conditions, when cultivated under waterlogging conditions. The
study was carried out in a greenhouse, utilizing 20 kg pots, filled with a lowland soil.
The effects of two sources of calcium (CaCl2
, 300 kg ha-1 and CaSO4
, 500 and 1.500 kg
ha-1) and three modes of application (applied 8 cm below surface, mixed with the whole
soil volume and surface application) were tested in soils kept at field capacity and
waterlogged after plants reached growth stage V6. Above ground biomass yield, the
contents of total soluble sugars and reducing sugars and the activities of the neutral
citosol (INC), acid vacuolar (IAV), acid cell wall invertases and phosphoenolpyruvate
carboxylase were determined at the onset of flowering. Calcium application partially
relieved the deleterious effect of waterlogging on biomass yield and the activities of
INC, IAPC and PEPcase. |
