Preliminary Observations on the Golorimetric Assay of the Hatching Factor of the Potato-root Eelworm, Heterodera rostochiensis Wollenweber

  • C. Ellenby (a1)
Extract

Promising results in the colorimetric assay of potato-root eelworm hatching factor have been obtained with picric acid and with 3: 5- dinitrobenzoic acid. Both of the reagents are used for the assay of cardiac glycosides with which the hatching factor may have affinities.
