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 hariber 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 §j 
fruiting capacity of the stripped plants. The stripped plants in the 
April 5 planting averaged 83.6 squares per plant, while the unstripped 9
