The preceding table gives results of pruning to the one, two and 

 three shoot systems as compared with normal or unpruned plants. 

 When the experiment was completed all the remaining green fruit 

 was picked and weighed, but the green fruit is not included in the 

 table, and if added it would not materially affect the results. The 

 largest amount of fruit was given by the normal plants, while the 

 least amount of fruit is given by the single shoot system. The aver- 

 age weight of the individual fruit is less for the normals than for any 

 of the others, while the three shoot system gave the highest average, 

 followed by the one and two stem plants. The plants in the three 

 shoot system in this experiment had the leaders removed just above 

 the fourth cluster of fruit, consequently they were restricted in the 

 amount of fruit formed and in their stem development. The average 

 weight of fruit per plant is the largest in the three stem plants and the 

 smallest in the single shoot system, but the average nuiuber of fruit 

 per plant is greatest on the normals, followed by the two, three and 

 one stem plants. The fruit, however, matured earlier in the single 

 shoot system. 



During the first eight days of harvesting, the amount of matured 

 fruit obtained from the various systems was as follows : Single stem, 

 21 ; double stem, 11 ; three stem, 19 and on the normals 2. For the 

 first 15 days of harvesting we have 57 matured fruit for the single 

 stems, 45 for the two stems, 49 for the three stems and 28 for the 

 normals, thus this experiment shows considerable gain in maturity of 

 fruit as a result of pruning.
