      abstract     = {Winter wheat plants (Triticum aestivum L. cv. Urban), grown
                      in nutrient solution, were exposed to differential
                      shoot/root temperatures (i.e., 4/4, 4/20, 20/4 and 20/20
                      degrees C) for six weeks. Leaves grown at 4 degrees C showed
                      an increase in frost tolerance from - 4 degrees C down to
                      -11 degrees C, irrespective of root temperature. In 4/20
                      degrees C plants, high root temperature decreased the rate
                      of hardening of the leaves, but did not influence the final
                      level of frost tolerance. In roots grown at 4 degrees C
                      frost tolerance increased from - 3 degrees C down to - 4
                      degrees C, independently of shoot temperature. An
                      accumulation of soluble sugars in the leaves was only
                      observed when both shoot and root were grown at 4 degrees C
                      and was not correlated with final frost tolerance achieved.
                      However, the rate of hardening was correlated with the
                      soluble sugar concentration. An increase in root soluble
                      sugar concentration was exclusively observed in roots
                      exposed to a temperature of 4 degrees C, irrespective of
                      shoot temperature. Proline concentration only increased in
                      plant parts exposed to a temperature of 4 degrees C. The
                      present results indicate that the importance of root
                      temperature in low-temperature hardening of winter wheat is
                      limited, even though exposure to differential root and shoot
                      temperatures brought about pronounced changes in growth,
                      soluble sugar concentration, insoluble sugar concentration
                      and proline concentration in roots and leaves.},
