Salt Requirements for Buckwheat Plants 
171 
(A and B) of the two developmental periods here considered, and also 
the data of water requirements for the cultures of the two series. The 
various measurements for each culture are expressed in terms of the cor¬ 
responding measurement for culture R1C1 in the respective columns. 
The actual value for this culture is given in each case in parentheses just 
below the relative value, 1.00. In columns 2 and 3 are given the relative 
amounts of water loss for the cultures of series A and B, respectively. 
Then follow two columns presenting the relative water requirements of 
tops and roots for series A. The last three columns give the relative 
water requirements for tops, roots, and seeds, for series B. 
Table) V .—Data of transpiration and water requirement: series A , grown to the flowering 
stage; series B, grown from the flowering stage to maturity in 3-salt solutions
