The interrelation between elongation and IAA-1-14C metabolism in wheat coleoptile sections

  • Elwira K. Lis

It has been shown that intensive elongation of wheat coleoptile sections is correlated with indoleacetic acid-1-14C metabolism. In tissues actively growing the disappearance of indoleacetic acid-1-14C and formation of conjugates and metabolites (indoleacetamide, indoleacetyl-β-D-glucose, indoleacetyl aspartic acid) is twice as high as in sections where growth has been stopped by physical constraint (plaster) or in tissue which did not elongate by an unknown reason.

Vztah mezi prodlužováním a metabolismem kyseliny indolyl-3-octové-1-14C u sekei koleoptili pšenice


Intensivní prodlužování sekcí koleoptilí pšenice souvisí s metabolismem kyseliny indolyl-3-octové-1-14C.V aktivně rostoucích pletivech je rozklad kyseliny indolyl-3-octové-1-14C a tvorba derivátů a metabolitů (indolylacetamid, indolylacetyl-3-D-glukosa, kyselina indolylacetylasparagová) dvakrát vyšší než v pletivech nerostoucích z jiných, neznámých důvodů.
