102 EXPERIMENTAL PLANT PHYSIOLOGY 



Observations. — In a few days the damaged seedling 

 produces two new shoots which emerge from the ground 

 by the side of the cut stem (Fig. 53). On taking this 

 seedHng out of the earth and examining it, the two

shoots are seen to be borne in the axils of the coty- 

 ledons. 



Inference.— In the broad-bean, buds are borne in the 

 axils of the two cotyledons. These buds usually re- 

 main dormant, but they have power to develop should 

 the primary shoot be injured.
