e0“cowpea pre-exposed to drought priming acquired a stress imprint that alleviated the subsequent drought stress which occurred during the later growth stage as exemplified by the improvement of water status, photosynthesis, water productivity of biomass (WPb) and yield (WPy) as well as the modulation of plant hormones.”

Other claims from this paper (12)
- Intervention effect Priming improved cowpea photosynthesis during later drought.
- Intervention effect Priming improved biomass and yield water productivity.
- Intervention effect Primed cowpea had lower leaf ABA under post-anthesis drought than unprimed plants.
- Intervention effect Primed cowpea had higher leaf IAA under post-anthesis drought than unprimed plants.
- Mechanism Elevated leaf ABA was identified as the main reason for stomatal limitation under drought.
- Mechanism Stomatal limitation associated with elevated leaf ABA decreased photosynthesis.
- Mechanism Stomatal limitation associated with elevated leaf ABA led to yield loss.
- Intervention effect Primed V1 cowpea used 32% less water.
- Intervention effect Primed V2 cowpea used 24% less water.
- Intervention effect Drought priming significantly increased water productivity.
- Intervention effect Drought priming decreased intrinsic water use efficiency.
- Recommendation The authors suggest early drought priming to save irrigation water and improve water productivity where water is scarce.
