last two items in each column (numbered K and T, respectively) refer to 
the data obtained with the cultures grown in Knop’s solution and in 
Tottingham’s best solution for wheat tops, each with the same total 
concentration as the solutions of the 3-salt series. The cultures were 
included in each series for comparison. 
Table I .—Average dry weights of tops, roots , and seeds of buckwheat grown from the 
flowering stage to maturity in 3-salt solutions, all having a total osmotic concentration 
value of 1 .75 atmospheres , but differing from each other in the proportions of the 3 salts; 
also the ratio of tops to seeds
