EXERCISE 49. A STUDY OF RICE 



Equipment: A supply of rice heads comprising two or 

 three different varieties such as Honduras, CaroUna and 

 Japan. 



Method: Give each student a head or a few grains of 

 each variety and require him to fill in the outline given below : 



Variety . 



Color of hull 



Color of cuticle 



Density of endosperm 



Endosperm vitreous or white. 

 Average length of 10 grains. . 

 Average width of 10 grains . . 

 Average length of 10 kernels . 

 Average width of 10 kernels . 



Weight of 10 grains 



Weight of 10 kernels 



Per cent of hull to grain 



How many grains on an average head of rice? 



How is the rice grain prepared for table use? 



Discussion: The greater part of the rice produced in the 

 United States is grown by the wet-culture method. The 

 land is flooded immediately after planting in order to sprout 

 the seed. As soon as this is accomplished the water is with- 

 drawn until the plants have attained the height of six to ten 

 inches, at which time the land is again flooded and the water 

 retained until the grain is in the milk stage, when it is again 

 removed to permit the grain to ripen.
