The average number of internodes per fruiting branch was ob- 

 tained for the stripped and unstripped plants in each planting. For 

 convenience, these data have been arranged in groups of five consecu- 

 tive fruiting branches and are presented in Table 25.

A consistently larger number of internodes was formed on the 

 fruiting branches of the stripped plants in the April 5 and April 16 

 plantings. As the total number of fruiting branches was practically 

 the same on the stripped and on the unstripped plants the increase 

 in number of internodes on fruiting branches resulted in a greater 

 fruiting capacity of the stripped plants. The stripped plants in the 

 April 5 planting averaged 83.6 squares per plant, while the unstripped
