Table 13. Average Temperature in the Rice 

 Crop Season. 



As noted before, the length of vegetative growth and matur- 

 ation may exert some influence on the increasing rate of accumulation 

 of dry matter during the whole life of the rice plant. Unfortunately 

 we have not sufficient date to enable us to come to definite conclus- 

 ions on this subject, but a few facts are given below, by means of 

 which the increasing rates of dry-matter accumulation in the entire 

 plant can be compared.

 Dry Matter.
