GERMINATION OF SEEDS 71 



56. EFFECT OF MUTILATION 



Object. To learn the result of removing other parts of 

 seeds. 

 Apparatus. Same as in the preceding Experiment. 



Method. Prepare tumblers as before or fill several 

 glasses two thirds full of damp sand and cover them with 

 glass. 



Remove the tip of the first stem (hypocotyl) from beans 

 and peas. Carefully remove the first bud (plumule) from 

 a bean without breaking the seed leaves apart. Cut away 

 as much as possible of the endosperm from a soaked grain 

 of corn or a castor bean. Then place these mutilated seeds 

 on the cheesecloth or upon the moist sand and let them re- 

 main for ten days. Result in each case ? 



Conclusion. State your inferences as based upon these 

 observations.
