Abstract
Gould, R. P., Minchin, P. E. H. and Young, P. C. 1988. The effects of sulphur dioxide on phloem transport in two cereals.—J. exp. BoL 39: 997–1007. In vivo investigations using 11C-labelled photosynthate revealed that there is a change in the patterns of tracer profiles when cereal leaves are exposed to SO2. The change after exposure to SO2 was interpreted in terms of a decrease in lateral water flow into the sieve tubes brought about by reduced phloem loading along the length of a leaf. Analysis also revealed that the speed of translocation was reduced, as expected by the Munch model of phloem transport.This publication has 14 references indexed in Scilit:
