Effect of synthetic cyclopentane [beta],[beta]'-triketones on amino acid metabolism in roots of buckwheat (Fagopyrum esculentum Moench.) seedlings

摘要

Germination of buckwheat seeds in solutions of synthetic mono- and tricyclic cyclopentane β,β'-triketones of various concentrations was accompanied by inhibition of seedling root growth and changes in the contents of glutamate, γ-aminobutyric acid, proline, glutamine, and alanine. The monocyclic triketone also affected the amount of isoleucine. It is likely that the increase in proline content is a nonspecific response significant for enhancing stress tolerance in seedlings.
