摘要
Postflowering heat stress causes the arrest of kernel growth, increasing kernel protein concentration and the relative abundance of g-zeins, two biochemical traits contributing to maize (Zea mays L.) hardness. The impact of early and late postflowering heat stress on kernel physical traits related to hardness was studied on field-grown maize hybrids differing in their prevailing endosperm texture (two hybrids with a vitreous texture, and two others with a floury texture). Kernel texture was softened by heat stress (P < 0.001), as indicated by decreases in traits that are usually positively related to hardness (thousand-kernel weight [up to 185 g], proportion of large kernels [up to 50-65 percentage points], kernel or bulk density [up to 7 kg hL(-1)] and milling ratio [up to 1 g g(-1)]) and increases in those usually negatively related (proportion of the smaller kernels and floater percentage [up to 30 and 75 percentage points, respectively]). Most of these effects were larger (P < 0.01), as heat stress occurred earlier in the grain-filling period. Kernel physical traits of the genotypes with a predominantly floury texture varied the most (P < 0.05) in response to heat stress. Genotypic and environmental variation effects in most hardness-related traits could be accounted for by kernel density (r(2) = 0.74-0.87) or bulk density (r(2) = 0.79-0.93). Sowing date and genotype selections should be considered as crop management practices for reducing or preventing the potential impact of heat stress on maize hardness.
