---|---|---|
Cool | Hot | |
Early leaf growth | + | + |
Respiration | + | + |
Assimilation | + | − |
Cold sterility | − | 0 |
Heat induced sterility | 0 | + |
Length growing period | − | − |
Evapotranspiration | + | + |
a + means the process is increased, a − means it is decreased and a 0 means no change. A + does not per definition mean a positive effect on yield. If heat induced sterility increases or if respiration increases, then yield can decrease.
