Wheat wilted and leaves of rush dying back 

 simultaneously. Corn in same pot wilting 

 at the same time. No recovery in damp 

 chamber. 



Wilted simultaneously. Pots allowed to 

 stand too long before moisture determina- 

 tions were made.

Wilted simultaneously. No evidence of dif- 

 ference. Colocasia has poor root distribu- 

 tion. Neither wheat nor colocasia recov- 

 ered in damp chamber. 



Submerged plants transplanted and kept in 

 glass damp chamber. Outer leaves dying 

 (do not wilt) simultaneously with the wilt- 

 ing of the wheat plants. Poor root distri- 

 bution of both wheat and Isoetes. 



Wilted simultaneously. Poor root distribu- 

 tion.
