The history of fruit thinning

  • F.G. Jr. Dennis


The history of fruit thinning is reviewed, beginning with hand removalof fruits, the effects upon subsequent flowering, and current attemptsto develop mechanical methods of fruit removal. Early experiments withcaustic compounds and growth regulators and their subsequent developmentas commercial practices are discussed, as well as the modes of action ofgrowth regulators. Brief reviews of methods of application, factorsaffecting response, modeling to improve efficiency, and the economicvalue of thinning to the grower are also included.
