Abstract
Warmth accelerates the rate of grain growth in wheat, but the temperature coefficient expressed as Q <sub>10</sub> decreases gradually between 10 and 25°C. The rate of protein deposition responds more to temperature than the total grain dry matter accumulation rate. Warmth shortens the post-floral phase in cereals. The relation can be approximated by a direct log-linear relationship between temperature and duration, or by a heat sum above a minimum temperature. The proportion of the final amount of nitrogen in the shoot taken up by the roots after anthesis declines upon increase in the concentration of nitrogen in shoot dry matter at anthesis. The component shoo...
