 (Cornell) Varieties. To iise the measurement of the basal metabolism 

 rate (respiration rate) of apples to build up a store of 

 information that may be used In practical application.

Oreg . Physiological Problems In Relation to the Maturation 

 and Storage of Fruits. 3« Methods for Improving the 

 Keeping Quality of Anjou Pears In Cold Storage. T o Investi- 

 gate methods for extending storage life of Anjou pears three 

 methods will be studied, (l) Lowering storage temperature. 

 Use an experimental storage room in Horticulture Department 

 where temperature, humidity, and air movement rate are closely 

 controlled. Store peairs at 28-28.5° core temperature, with 

 95-96^ hvunldity. Store control at 30° with same himidity. 

 Follow differences in firmness, skin blemishing, color, 

 soluble pectin, and eating quality. (2) Control of volatiles. 

 Store samples of pears in storage room with activated carbon 

 scrubber units and in similar room without carbon. Keep 

 both storage rooms at 30°, using similar lots of pears which 

 represent veurious growers, locations, sizes, etc. Make pres- 

 sxire tests and soluble pectin analyses monthly during storeige. 

 Analyze carbon to determine percent saturation, ^ich affects 

 efficiency of absorption. (3) Modified atmosphere storage. 

 Make tests with modified atmosphere storage dxiring 1952-53 

 season, with procedures to be outlined after survey of liter- 

 at\ire on types of equipment and concentrations of CO2 and 

 oxygen .

Oreg . Cost and Efficiency Compeurisons of New Methods and Eqvip - 

 ment Used in Handling and Packing Winter Pears . To (1) learn 

 and evaluate coii5)aratlve costs and efficiencies of new hand- 

 ling and packing methods and equlpnent; and, (2) recommend 

 changes in methods and equijaient that will reduce costs and 

 increase efficiency in hemdling and packing at shipping point.

Va, MatTirity and Physiological. Responses of Apples as Influ - 



enced by Fertilization, Spray Practices, Environmental Condi - 

 tions, Harvesting and Handling^ To (1) develop maturity stem- 

 dards for harvesting apples for eaorly market and for cold 

 storage; (2) learn influence of weather and cultural practices 

 on quality, condition and storsige life; and, (3) evaluate 

 influence of spraying, fertilization, harvesting and handling 

 practices on quality, condition and storage life,
