unpruned plants. Com- 

 pare Figures 2, 3 and 5. 

 In the single shoot system 

 the plants were pruned 

 to a single leader, and 

 the two, three and 

 four shoot plants were 

 •^^^ obtained by allowing the 

 l) ll \b strong secondary branch- 

 es to develop. In addition 

 to the above systems of 

 pruning, in some cases 

 cutting the leader or head- 

 ing in was practiced. In 

 all instances where prun- 

 ing was practiced the 

 supernumerary axillary 

 shoots, or suckers, occur- 

 ing on the plants were cut 

 out as soon as they be- 

 Fig. J. came at all conspicuous. 



Three Stem Plant, Leaders Cut. In the normal or 



unpruned plants these axillary shoots were not interfered with, con- 

 sequently they had an abundance of folinge due to non-restricted 

 growth. In all cases the seeds were sown in flats and when they had 

 attained a height of four or five inches they were transplanted into 

 3 inch pots. They were subsequently transferred to 6 inch pots and 

 in some cases were further transplanted into 12 inch pots. When 

 the plants were from one foot to eighteen inches high they were trans- 

 planted in the beds. In all the experiments careful records were 

 kept of the amount and weight of fruit obtained from each plant, and 

 the dates at which the fruit matured were recorded. 



In the following tables and the text, we have employed the words 

 stems, shoots and leaders as synonymous terms. Technically, the 

 tomato plant possesses but one true leader or stem, and the lateral 

 growths are branches. It is not an uncommon practice, however, to 

 use these terms as we have employed tlieni.
