METHODS OF PRUNING TOMATOES. 



THE INFLUENCE OF PRUNING, OR REMOVING THE 



LOWER -LEAVES, UPON THE GROWTH OF 



STEMS AND FRUIT OF TOMATOES. 



Some experiments 

 were made on a few- 

 plants in whicli their 

 growth was registered 

 and recorded, in some 

 instances each day. 

 The increase in the 

 size of the fruit was 

 also noted. The 



growth of tlie phints 

 was measured bv 

 means of a thread 

 attached to the apex of 

 the leaders and pass- 

 ing over a wheel which 

 gave an amplification 

 of about eight times to 

 the growth of the 

 ]Mant. The increase 

 in the size of fruit was 

 obtained either bv 

 caliper measurements 

 or by inmiersing in 

 water while the fruit 

 was attached to the 

 plant, the size of the 

 fruit being obtained by 

 the amount of dis- 

 placed water. In some 

 cases the fruit was
