Notes:
Summary Rape (Brassica napus) plants with either split or entire root systems were grown in a nutrient film system, with the shoots at a constant 25°C and the roots at a range of temperatures between 5° and 23°C. Provided part of the root system was warm, shoot growth was not affected by cooling the rest of the roots. The rate of growth of individual roots was increased with the temperature to which they were exposed. Inflow of phosphate was independent of temperature within the range 23°C–10°C but was halved at 5°C. Both the root extension rate and the phosphate inflow were unaffected by the temperature of the rest of the root system.
