In addition, according to the ANOVA results ( Table 2 ), the effects of different treatment stages (S), different low-temperature intensities (T), and their interactions (T×S) on the content and accumulation of mineral components in grains were highly significant ( p < 0.01). 3.3.
Both wheat cultivars showed a trend of increasing grain K content with decreasing temperature under low-temperature treatment applied at the jointing stage, while the variation in the grain K content of both cultivars showed a trend of first decreasing and then increasing with decreasing temperature under low-temperature treatment during the booting stage and combined stages.
