Adaptation to long-term cold-girdling in genotypes of common bean (Phaseolus vulgaris L.).

Abstract excerpt

The effect of long-term cold-girdling on phloem transport and resource allocation in whole plants of common bean is described. Wide differences were found between genotypes, with some maintaining translocation when cold-girdled. This provides evidence to support passive phloem transport. The possibilities that cold-girdling may physically block transport and/or disrupt root-shoot signalling are discussed.
