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.
