beneficial by Wiggans of Nebraska. Soil samples collected through 

 the year in a block of Delicious spaced 30 x 33 feet showed that 

 the rainfall vifas insufficient for both trees and cover crop and 

 that 15 inches of irrigation was necessary to meet all requirements. 

 Records on 7 varieties sho«ved an average of 9% of apples below 2-2-" 

 on the irrigated plots compared with 4-4^ on the non-irrigated plots. 



Does Internal Cork Disappear in Storage? 



There seems to have been some difference of opinion among 

 fruit grov/ers as to whether internal cork becomes more severe in 

 storage or not. As a means of finding a possible ansvrer to this 

 question samples of Mcintosh apples were taken from certain orchards 

 in Middlesex County v."here internal cork v;as particularly trouble- 

 some. These apples were then sent to the Pomology Department at 

 the State College for observation. On September 26 a composite 

 sample of the apples was divided into three lots. One lot was ex- 

 amined immediately to determine the amount and severity of internal 

 cork at harvest time. One lot was placed in cold storage and the 

 other in common storage. On November 25 one-half of each lot 

 placed in storage was examined and the other half was allowed to 

 remain in storage for further observation. On February 1, the 

 final lot was removed and examined. A small sample each of Cort- 

 land and Baldwin was treated in a similar manner. 



The results of this experiment suggest the following 

 conclusions: (l) Apples that are free from internal cork when 

 placed in stort^ge do not acquire it. (2) That internal cork in- 

 creases in severity the longer the apples are held in storage. 

 (3) That there is no relationship between the type of storage, 

 whether cold or coimnon, and the increase in severity of internal 

 cork. (4) There is no evidence that apples affected v/ith internal 

 cork when placed in storage will ever recover from it. 



As a supplementary p^rt of this experiment the effect of 

 internal cork on the cider making properties of apples v/as studied. 

 In this experiment apples showing none or a mere trace of internal 

 cork were compared with those sliowing medium and heavy amounts. 

 The results indicate that apples show^ing internal cork produce 

 about 10$^ less cider per unit of fruit than sound apples. Also, 

 the cider from corky apples has more sediment and is less acid than 

 that fro;, sound apples. 0. C. Roberts 



February Cold Storage Report 



According to the Agricultural Marketing Service, cold 

 storage stocks of apples were reduced 5,886,000 bushels during 

 January. For the same month in 1939 the figure.. was 5,593,000 and 

 for the 5-year average - 5,297,000. Stocks on hand February 1, 

 amounting to 20,312,000 bushels, were 661,000 bushels less than 

 those of a year earlier and 1,64-9,000 bushels below average. Kov/- 

 ever, Nevv' England and Nev^r York holdings (largely Mcintosh) on Feb- 

 ruary 1 were considerebly above those of a year ago. For Vermont, 

 Connecticut, Massachusetts and New York the comparative figures 

 v/ere 5,109,000 (19^0) and 4,013,000 (1939).
