11 



Table V shows tliat the removal of lateral roots promoted 

 floweriug and produced more flowers than in the control. 



In this experiment, the lateral roots were removed as in 

 experiment I, except that the number removed was smaller. 



(G) Vicia Faba var. equina. 



Tiio plants were arranged in two series, of which one re- 

 mained as control. In each plant of the other series, five lateral 

 roots were removed and afterwards a part of the main root and 

 a few secondary roots were removed, once every ten days. 



The following table shows that the floweriug of the first 

 series came earlier on account of the removal of the roots.
