3.8 Correlations between KN/ear, TKW, yield, and high
temperature in short episodes around flowering and early grain fillling
Correlation analysis was conducted between
KN/ear, TKW, yield and the average
daily maximum temperature during one week before flowering (WBF),
flowering (0), one, two, three, four weeks after flowering (WAF),
respectively (Figure 9). Most of the correlations were negative. The
significant correlations between KN/ear, yield and temperature were
mainly found in the period of time1-3 WAF. Compared to KN/ear, only a
few significant correlations were found between TKW and temperature that
were mainly distributed at 1 WBF and 2-4 WAF. Te×Tr had more significant
correlation events and Te had the fewest significant correlation events
between KN/ear, TKW, yield, and temperature.
