Abstract
Various stages of plant growth and development could greatly be affected by
abiotic stresses. Among them, two significant abiotic stressors, including drought and
heat, hinder crops’ vegetative or reproductive growth stages, which in turn affect
sustainable agriculture worldwide. The incidence of drought coupled with heat stress is
increasing mainly due to global climate change. It was proved that the effect of drought
coupled with heat stress is additive when compared to individual stresses. This chapter
focuses on the influence of common dual-stress heat coupled with drought stress on
plants. A critical understanding of how different plants respond to heat coupled with
drought stress would pave the way to developing suitable agronomic management
practices for better crop genotypes with improved productivity.
Keywords: Drought, Drought coupled with heat, Heat stress, Plant stress.
