"şecause of the lack of rool formationon apple cuttings. the reIationshipcould not be determined betweeneudogenous hormons and root· formation.3. On the other hand ther was adear relationship between endogenoushormons and root formalions ofgrape ,cuttings.4. The application of 4000 ppmIBA externally caused more, root formationon the grape cutling in comparisonwİth the control samples.5. The highest rate of root formatiantook place on basel cuttings of grapein ·all four sampling stages. In .additionto them the intermediate and apex cuttiııgstaken in March also indicated highlevel of root formation ratios.6. The endogenous hormons extractedfrom apple cuttin.gs and grapecuttings after dipping them in distiIJedwater for 24 hows were assayed on oatcokoptite. The Rf values of there endogenousborınoas were found as fal·law. The Rf values of growth inhibitorsexttacted from apple cuttings were foundin the section of Rf: 0.1-0.2; 0.3-0.7The Rf values of growth stimulatorsof grape cuttings were found in thesections of. Rf: 0.7-1.0; 0.1-0.3; 0.70.9.In generaııy the. growth inhibitorsof grape were found in Rf: 0.6-0.8 and0.8-1.0 sectipııs and the growth stimulatorsof grape were found in Rf:0.1-0.5; 0.9-\.0 sections.The growth stimulators were affectivein March samples of both applecuttings and grape cuttings.
