20% of the apples stored immediately after picking. As is to be ex- 

 pected, holding the apples at 65° for 10 to 20 days after picking caused 

 excessively early ripening and reduced the market period by 50% or 

 more. 



On March 6 Mcintosh from the lot stored immediately were in fair 

 condition 17 days after being removed from storage and placed in a 

 room at 65° F. Those from the lot delayed 5 days were overripe but 

 edible. On April 6 Mcintosh from the lot stored immediately or de- 

 layed 5 days remained salable for 18 days after removal from cold 

 storage, the other 2 lots less than 7 days. 



Mcintosh stored at 30° showed slightly better pressure tests after 

 March 15 than those stored at 32°. In common storage both pressure 

 and acidity dropped rapidly after February 20. The flavor at 32° 

 was rated very good between December 20 and May 1. At 30° the 

 fruit remained rather green up to February 20 and was considered 

 fair until August 20. It never attained the maximum quality. 



As in the case of the Baldwin apples, fruit from sod orchards 

 showed no significant difference in storage from fruit from cultivated 

 orchards. 



The observation that if promptly cooled when stored, holding Mc- 

 intosh 5 days after picking at 65° reduces brown core and improves 

 flavor, needs to be confirmed by further investigation. If confirmed 

 it means that ordinarily sorting and packing may be done before 

 storing the fruit without fear of deterioration. Fruit may also be 

 moved to storage at the market during this interval. (Purnell Fund) 



Pollination of Apples 



Several of the newer Mcintosh and Delicious seedlings were tested 

 as pollenizers by L. P. Latimer in two localities. The results indicate 

 that Medina, Milton, Lobo and Melba are satisfactory pollenizers for 

 the Mcintosh and the Cortland. Red Gravenstein, like its parent, is 

 unsatisfactory. Orleans proved satisfactory with the Mcintosh but 

 was not tested with the Cortland. As in previous seasons, Delicious 

 proved to be one of the best pollenizers for Mcintosh, followed closely 

 by Wagener. Cortland also proved good. The Golden Delicious in- 

 sured a satisfactory set on the Cortland, but Yellow Transparent did 

 not. Fameuse, tested for the first time this season, gave a very satis- 

 factory set on the Mcintosh. It is interesting to note that the seedlings 

 of Mcintosh have uniformly proved to be good pollenizers for the 

 parent variety. 



Further observations on the relation of pollination to seed formation 

 and the conformation of the fruit agree with those of previous sea- 

 sons, namely that if an efficient pollenizer is used and a large number 

 of seeds develop the fruit tends to be larger and of more uniform shape. 

 It was again found that fruit developed from the terminal flower of 

 the cluster is 15 to 20 per cent, larger than that produced on lateral 

 blooms. (Purnell Fund)
