Given that heat exposure during the flowering (±7 days of silking) stage has been shown to decrease grain number, grain size, and final grain yield in previous studies (Wang et al., 2019; Liu et al., 2022), we divided the maize development stage into three phases to differentiate the impact of heat stress on yield during the flowering phase.
