R. Mahla; S. Madan; R. Munjal; et al. Quality Assurance and Safety of Crops & Foods 2012. doi:10.1111/j.1757-837x.2012.00141.x
Other claims from this paper (13)
- Intervention effect Heat stress increased leaf H2O2 production in both tolerant and susceptible wheat genotypes.
- Observation Under heat stress, susceptible wheat genotypes had significantly more H2O2 than tolerant genotypes.
- Intervention effect Heat stress enhanced CAT, POX, GR and APX activity in leaves of both wheat genotype classes.
- Observation The percentage increase in antioxidative enzyme activity under heat stress was higher in tolerant wheat genotypes.
- Intervention effect Heat stress increased SOD activity in tolerant wheat genotypes.
- Intervention effect Heat stress decreased SOD activity in susceptible wheat genotypes.
- Intervention effect After revival, CAT, POX and GR activities declined relative to stressed wheat seedlings but remained above controls.
- Mechanism Higher H2O2 accumulation in wheat was linked by the authors to disrupted membranes and greater MDA content.
- Intervention effect After revival, H2O2 and MDA content fell in all wheat genotypes but stayed above controls.
- Observation Heat stressed WH-1021 seedlings displayed five new polypeptide bands.
- Observation Heat stressed HW-2045 seedlings displayed five polypeptide bands.
- Observation The two susceptible wheat genotypes showed similar high temperature induced polypeptide bands.
- Mechanism Authors suggest greater heat tolerance of HW-2045 and WH-1021 may reflect heat shock proteins and oxygen scavenging enzymes.
