accumulated temperature

A Dictionary of Plant Sciences

accumulated temperature A surplus or deficit of temperature with respect to a defined mean value and expressed as an accumulation over a given period, e.g. month, season, or year. For example, a datum value of 6°C is used as a critical temperature for sustained vegetation growth.
