Table d.^Roots, relative dry yields (six plants) , from series with i-salt 
solution type A. 
[The value for culture TIRISI is always taken as unity and the others are expressed in 
terms of this. The actual value (grams) for this culture is given in parentheses below the 
assumed value of unity, in each case.]

The range limits given in the lower part of Table 6 indicate 
a less marked distinction in favor of the two medium total con- 
centrations (as compared with the lowest and highest, series 14 
and 20) than is shown for top yields. Nevertheless, partly 
because the physiological meaning of the dry yield of roots is
