| Abstract: | Glycinebetaine and choline, which stimulate the growth of Fusarium graminearum both in vitro and in vivo, are present in higher concentrations in wheat anthers relative to any other organ as measured both by the periodide assay and a bioassay. This finding provides an explanation for the onset of greatly increased susceptibility of wheat to F. graminearum at anthesis. |
