PLANT RESPONSE—ON THE EFFECTS OF SINGLE STIMULUS 
AND OF SUPERPOSED STIMULI 
Effect of single stimulus—Superposition of stimuli—A dditive effeet— 
Staircase effect—Fatigue—No fatigue when sufficient interval 
between stimuli—Apparent fatigue when stimulation frequency 
is increased—Fatigue under continuous stimulation 2 :
