Abstract Temperate and tropical maize differ in their tolerance to heat stress but the ecophysiological bases for genotypic differences are poorly understood. Our objectives were (i) to assess the sources of kernel loss, and (ii) to identify the main differences in these traits among genotypes of contrasting genetic background. We used the classic relationships that associate final kernel number per plant (KNP) with plant (PGR CP ) and ear (EGR CP ) growth rates during the critical period for… CONTINUE READING
