FRUIT PRESSURE TESTERS

are rather uniform and variations might be attributed to the differences 

 in judgment of the various investigators. Where two values are given 

 for the upper limit of the pressure test, the higher value represents a 

 condition in which the fruit is passable but will generally develop only 

 fair dessert quality and the lower value represents the optimum point 

 at which to start harvesting.
