Summary
By means of theAvena section test in conjunction with paper chromatography very efficient growth inhibiting substances of acid nature, but no native auxins, could be demonstrated in ether extracts of Zea mays coleoptile tips. However it was possible to show that in the same extracts as much as 10−5 g of added IAA was no longer demonstrable by either method. The significance of these results for the evaluation of rerent findings on the nature of auxins in Zea mays seedlings is discussed.
