ResumoThe response of translocation in I. alba to stepwise heating and cooling of 80-mm segments of stem was studied by pulse labelling with naturally loaded 11C. Translocation was indifferent to positive- going temperature steps within its normal physiological range; it was, however, momentarily disrupted by negative-going steps, even as small as that from 27.1�C to 21.4�C, i.e. 5.7�C.
