Abstract
IN senescent leaves proteins are hydrolysed to amino-acids and peptides1, which might be expected to release protein-bound auxin and also to provide considerable amounts of tryptophan which can be converted by many plant tissues to the auxin indolyl-3-acetic acid (IAA). We have therefore investigated the concentrations of auxin in senescent leaves.
