Concl usions : In general , it can be said that waxing distinct- 

 ly improved the glossiness and overall appearance of most fruit. 

 It was noted, however, that this increased glossiness accentuated 

 imperfections such as bruises or russeting. Waxing also reduced 

 shrinkage of the apples under adverse conditions and delayed shriv- 

 eling of 'Mcintosh' and 'Delcious' but not of 'Golden Delicious.' 

 Furthermore, it delayed yellowing of 'Mcintosh' fruit. It had no 

 adverse physiological effects at the rates of application employed 

 in these tests. Caution must be exercised though, for heavier ap- 

 plications are known to cause fermentation and off-flavors of the 

 f rui t . 



As to whether or not waxing should be employed, the individual 

 apple packer will have to weigh such factors as the additional cost, 

 potential danger of over-waxing and induction of fermentation, and 

 possible accentuation of the appearance of imperfections, against 

 the considerably greater glossiness, possible reduced shrinkage 

 during adverse conditions, and possible delayed yellowing of at 

 least some varieties of apples. Nevertheless, it seems that waxing 

 is now an established part of the fruit packing industry, and the 

 pressure on the individual packer to conform to the industrial trend 

 will likely grow.
