Mich . Frost Control on Vegetation by Convected Heat, Infra - 

 red Radiation and by Sprinkler Application of Water J To 



(1) investigate all possibilities of generating Infra-red 

 which would be adaptable to frost control, and develop 

 methods and equipiaent entailing lowest manxifacturing costs, 

 iising liquid fuels, and using LP gasj and, (2) investigate 

 possibility of using helicopter rotor as a aaethod of bring- 

 ing warm upper air down on the crop, with added heat.

Mich . The Interrelation of Environment (Temperature and Rela - 

 tive Humidity) and Spray Chemicals on Russetlng, Lustre , 

 Color and Ripening of Apple Fruits and on Physiology of 

 Apple Leaves . To determine (1) environmental conditions 

 and tias during flower and fruit development that fruit 

 russetlng is most likely to occur from use of chemicals; 



(2) if Injury to epidermal cells of flower and fruit is 

 necessary for occurrence of russetlng by pesticide chemicals; 



(3) relation between apple varieties and injury from various 

 chemicals as influenced by temperature and humidity; and, 

 (k) Interrelation of plant regulators used to control pre- 

 harvest fruit drop and night and day teaiperature on rate of 

 fruit ripening.

 and vegetables by methods of prepcuratlon for freezing and 

 free zlng-s tor 6ige being recommended by the station; (2) color, 

 texttire, and any other quality factors possible by objective 

 tests in fruits and vegetables frozen and stored by the 

 methods referred to In (l); and, (3) to use measurements In
