Harvesting Cultivated Blueberries Mechanically - According to 

 J.H. Levin, Leader, Fruit and Vegetable Harvesting Investigations, 

 AERD, ARS, USDA, East Lansing, Michigan, over 85% of the 1965, blue- 

 berry crop in Michigan was harvested with hand held vibrators. 

 These devices enable a worker to harvest blueberries at rates 6-7 

 times as fast as by hand. - (Levin, J.H. 1967. Harvesting fruits

Effect of Sunlight on Apples During the Growing Season : The ef- 

 fects of exposure to different amounts of sunlight on size, color, 

 soluble solids, firmness, acidity and pH of Mcintosh and Red Deli- 

 cious apples were studied by D.R. Heinicke and reported in Volume 



89 of the 

 Science 



Proceedings of the American Society for Horticultural 



The study showed that there are 3 distinct light zones in 

 apple trees which affect fruit quality in British Columbia: a zone 

 of inadequate light for marketable fruit (less than 40% full sun- 

 light (FS); a zone of adequate light (40 to 60% FS); and a zone 

 for optimum development of fruit quality (above 60% FS) 



Mcintosh decreased with increased light exposure. Heinicke be- 

 lieved, however, that this was an indirect effect of light caused 

 by its effect on fruit size and maturity, rather than a direct 

 effect of light exposure. Nevertheless, it is interesting to 

 note that there was no firmness difference in Delicious despite a 

 substantial size difference. The pH and acidity of the juice from 

 fruit of neither variety was affected by light exposure.
