Nodulated white clover plants ( Trifolium repens L.) of a Norwegian ecotype from Pasvik (70° N) were grown in flowing solution culture. Root temperature was 17 °C until 51 d after sowing, when it was lowered decrementally over 5 d to 7 °C in four of the eight plant culture units. After a further 24...
