The submerged rice plant grows in a somewhat different way. 

 The weight remains about constant after the time of flowering, as 

 shown in the following tables : 



Table 3, Total weight of Rice Plant in a Fresh State. 

 ( 10 bundles). 



It is clear that variation in weight during maturation depends 

 upon the increase of dry matter and the loss of water contained in 

 the plant body. Evaporation from the swamp rice plants, such as 

 we are experimenting with, may be compensated for by a much 

 more easy and rapid abso/ption of water than in the case of crops 

 grown in dry fields e. g. oats. Consequently the oat plant is found 

 to have a considerable loss of water in the period of maturation, 

 though the dry matter increases in amount. Thus the weight of the 

 oat-plant decreases towards maturity, while that of the rice plant 

 remains about constant during the same period.
