EXAMINATIONS OF APPLE STAKGH. 97 



apparent in the outer portions, producing a slightly streaked appear- 

 ance. The beginning of the decrease in the amount of starch in the 

 oval zones is not so plain in this as in some other varieties. 



On October 15 the starch was all gone and the fruit had every 

 appearance of being fully ripe. Specimens were also examined on 

 October 23, October 30, and November 5, but no material change was 

 noticeable except an increasing mealiness in the texture of the tissue. 



From these facts it would appear that the ripening of the Hunts- 

 man begins about the last of August. The first period extends over 

 about three or four weeks and the second stage is completed by the 

 middle of October. 



YELLOW TRANSPARENT ( PLATE v). 



On July 24 this variety was found to have reached the second stage 

 in the course of ripening. It is true, however, that considerable 

 starch still remained within the core line while a decided loss of starch 

 seemed to be occurring in the torus flesh. The specimens examined 

 on July 29 showed but little change from this condition, and nearly a 

 month elapsed before specimens were again examined. The photo- 

 graphs made showed how slowly the second stage of ripening some- 

 times progresses. At this time it was found that the starch was all 

 gone from within the core line, while a considerable amount still 

 remained in the torus flesh. Specimens examined again August 31 

 showed that the starch had completely disappeared. 



It seems that the ripening period for the Yellow Transparent is 

 approximately from the middle of June to the latter part of August. 

 This variety also illustrates how irregularly many of the summer 

 varieties mature, many specimens being much in advance of others on 

 the same tree as regards ripeness. It is also true that this variety 

 does not strictly follow a given order of ripening, as is the case with 

 most winter varieties. 



EARLY STRAWBERRY (NOT ILLUSTRATE!)). 



These specimens had apparently ripened considerably while en route 

 to the laboratory. In this variety the starch had very largely disap- 

 peared from within the core line by June 25. Some streaking was 

 also appearing in the torus flesh. On July 24 the starch had decreased 

 very much in the outer portion. The V-zones were very well marked 

 in this variety. The specimens of July 29 showed but little advance 

 over those of the 24th, except that there seemed to be a slight weak- 

 ening in the intensity of the iodin reaction. Unfortunateh r this set 

 is incomplete both at the beginning and the ending of the maturing 

 period.
