Cortland 



This year was only the second that we have 

 followed the starch-iodine levels in Cortland 

 fruit; however, there were significant differ- 

 ences between 1990 and 1991. Figure 2 shows 

 the changes in starch-iodine values in 1990 and 

 1991. Fruit in the middle of the harvest season 

 in 1991 were approximately five days ahead of 

 those in 1990. I am not sure if 1990 was a normal 

 season, but these data are consistent with those 

 for Mcintosh and Empire. 



Empire 



Figure 3 shows the starch-iodine values for 

 Empire fruit during the harvest seasons from 

 1988 through 1991. As with Cortland the aver- 

 age fruit at mid-season in 1991 were approxi- 

 mately five days ahead of those in the previous 

 three seasons.
