AET. 4. — M. SHIGA : ON THE EFFECT 



From the above two experiments, we see that if the removal 

 is excessive, floweriüg is prevented, but if properly clone, it is 

 promoted. 



(5) Vicia Faha var. equina. 



On November 8th, the secondary roots of the second series 

 were all removed, and after that for a month, they were removed 

 repeatedly every four days, and in the next month once every week. 



After March 2nd, 1903, when the last removal took place, 

 the plants were left untouched. 



Knop's solution was used.
