It examines relationships between pollination intensity and key yield parameters such as fruit drop, seed number, and spur shoot characteristics, then tests growth-regulator applications at different plant levels. The study reports experimental results across multiple seasons and draws conclusions on effectiveness, fruit development outcomes, and related agronomic implications.","NN80  \n2000  \nTHE DROP OF FLOWERS AND FRUITSIN APPLE,WITH SPECIAL REFERENCETO THE JUNE DROP OFCOX’S ORANGE PIPPIN AND ITSCONTROL WITH GROWTH REGULATORS  \nBLOEM-EN VRUCHTVAL BIJ APPEL,MET NADRUKOP DE JUNIRUI VAN COX’S ORANGE PIPPINEN DE BESTRIJDING DAARVAN MET GROEIREGULATOREN  \n.J.WERTHEIM  \nC  \n# THE DROP OF FLOWERS AND FRUITS IN APPLE,WITHSPECIAL REFERENCE TO THE JUNE DROP OF COX'SORANGE PIPPIN AND ITS CONTROL WITH GROWTHREGULATORS\n\nBloem-en vruchtval bij appel,met nadruk op de junirui van Cox's Orange Pippin en debestrijding daarvan met groeiregulatoren  \nDit proefschrift met stellingen van  \nSAMUEL JOHANNES WERTHEIM,  \nLandbouwkundig ingenieur,geboren te's Gravenhage,26 maart1936,is goedgckeurd door de promotor,Dr.Ir.S.J.Wellensiek,hoogleraar in de Tuinbouwplantenteelt.  \nDe Rector Magnificus van de Landbouwhogeschool  \nJ.M.PoLAK  \nWageningen,5 oktober 1971  \nTHE DROP OF FLOWERS AND FRUITSIN APPLE,WITH SPECIAL REFERENCETO THE JUNE DROP OFCOX’S ORANGE PIPPIN AND ITSCONTROL WITH GROWTH REGULATORS  \nBLOEM-EN VRUCHTVAL BIJ APPEL,MET NADRUKOP DE JUNIRUI VAN COX'S ORANGE PIPPIN EN DEBESTRIJDING DAARVANMET GROEIREGULATOREN(with a summary in Dutch)  \nPROEFSCHRIFT  \nTER VERKRIJGING VAN DE GRAAD  \nVAN DOCTOR IN DE LANDBOUWWETENSCHAPPENOP GEZAG VAN DE RECTOR MAGNIFICUS,MR.J.M.POLAK,HOOGLERAAR IN DE RECHTS-EN STAATSWETENSCHAPPENVAN DE WESTERSE GEBIEDEN  \nTE VERDEDIGEN TEGEN DE BEDENKINGEN VAN EENCOMMISSIE UIT DE SENAAT  \nVAN DE LANDBOUWHOGESCHOOL TE WAGENINGENOP VRIJDAG 10 DECEMBER 1971 TE 16 UUR  \nDOORSAMUEL JOHANNES WERTHEIM  \nThis thesis is also published as Mededelingen Landbouwhogeschool Wageningen 71-17(1971)Communications Agricultural University Wageningen.The Netherlands  \nSTELLINGEN  \nI  \nDe rol die de wind speelt bij de overdracht van stuifmeel bij appel en peer isgroter dan algemeen wordt aangenomen.  \nWERTHEIM,S.J.Meded.Dir.Tuinb.31,1968:438-446.  \nII  \nEr is in de wereld plaats voor nog een tuinbouwkundig tijdschrift,speciaalvoor publicaties op het gebied van het teeltonderzoek van tuinbouwgewassen.  \nII  \nHet verdient aanbeveling om het chemisch ontsmetten van voor fruitteelt be-stemde gronden met chloorpicrine te vervangen door het planten van de bomenin plantgaten,die met verse grond gevuld worden.  \nWESTERLAKEN,J,De Fruitteelt 61,1971:100-102.  \nIV  \nDe vrees,dat vruchtbomen,vrij van de bekende virussen,wegens een sterkerevegetatieve groei minder vruchtbaar zouden zijn dan virus-bevattende bomen,lijkt ongegrond.  \nPEERBOOMs,H.De Fruitteelt 61,1971:94-96.  \nV  \nMet een gereorganiseerd afzetsysteem kan de Nederlandse fruitteelt een goedeconcurrentiepositie opbouwen.  \nVI  \nDe hoge kosten van plant-en steunmateriaal maken de aanlegkosten van in-tensieve appelboomgaarden zò hoog,dat het aanbeveling verdient het verede-lingsonderzoek te richten op het vervangen van de dure combinatie entras-on-derstam en op het onnodig maken van elke ondersteuning van de bomen.  \nVH  \nDe huidige criteria,die bepalen of een groeiregulator ontheffing krijgt voorpraktisch gebruik in land-en tuinbouw,dienen waar mogelijk te worden uitge-breid met de eis dat de betreffende verbinding van nature in de plant moet voor-komen.  \nVI  \nDe huidige verdeling van het tuinbouwkundig onderzoek in Nederland overtwee verschillende directies binnen het Ministerie van Landbouw en Visserij isondoelmatig.  \nCONTENTS  \n1.
