Weigel, U., Horn, W. and Hock, B. 1984. Endogenous auxin levels in stem cuttings of Chrysatuhemum tnorifoUum during adventitious rooting. -Physiol. Plant 61 • 422-428.Free and ester-bound IAA were determined in Chtysattthemum tnorifoliutn Ratnat cv. 'Yellow Galaxy' by means of a solid phase enzyme immunoassay. In shoots, free auxin decteases basipetally whereas ester IAA teaches a maximum in the middle part. After making the cuttings, a strong increase in both free and ester iAA (or total IAA, respectively) is found up to the time when the first adventitious roots become visible. Only prolonged irradiance of stock plants at high light intensities (40 W tn--) delays this increase in the cuttings, concomitantly with a lower number of roots compared to the controls (4.5 W m-), although root growth as determined by measuring root length or fresh weight is not affected. A distinct relation is found between IAA content of stock plants at the time when cuttings are taken and the number of adventitious roots formed by the cuttings 20 days later.Additional key words -^nzyrac immunoassay, light.U.
