RADISH 253 



"This table is representative of several similar and concordant 

 determinations made but not published. It shows the lower dry- 

 matter content of plants grown from large seed. The plants were 

 of the same age from seed, but were not of the same degree of 

 maturity. Plants grown from small seed were about a week later 

 in coming to edible maturity than those grown from large seed. 

 It is doubtful if an exact comparison could be made by allowing 

 the small seed crop to grow another week, for by so doing changed 

 soil and air conditions might intervene. However, the water content 

 of a radish is not a matter to cavil about. It is always extremely 

 high. Radishes are not eaten for the food they contain, but as a 

 relish. Good quality radishes must be rapidly grown, crisp and 

 succulent, no matter how high their water content. Aside from size 

 as related to quality, the plants grown from small seed were as good 

 as those grown from large seed. 



"The source of seed, whether from one parent or several, seems 

 to make little if any difference in the value of the product. The 

 following tables show the results of seed sorting according to size 

 when the seeds in a series are derived from the same plants, the 

 purpose in this instance being to eliminate the influence of indi- 

 viduality in different plants, and to insure similarity in such parental 

 factors as relate to vigor and general growth force.
