What reading level is A Study in Cereal Rusts Physiological Races book?
To quickly assess the difficulty of the text, read a short excerpt:
Minnesota No. 163 wheat was used. After inoculation plants were all placed under bell jars and kept under uniform conditions. Arranged according to virulence, the most severely affected being placed first, they would be arranged as follows: III, II, IV, I.
This was tried a second time with exactly the same results. The plants appeared about the same, all growing fairly well in the agar. All were well infected, producing a fairly large number of large, healthy pustules. They were kept three week...s after inoculation and by this time there was not much difference between II, IV, and I, but III was still much more virulently attacked. It seems, therefore, that an excess of nitrogen does not necessarily, in itself, cause an increase in the amount of rust and an excess of phosphorus does not affect it very appreciably.
The effect of excluding nitrogen and phosphorus was next tried. Sach's modified medium plus one per cent of agar was again used and in I no potassium nitrate was added while calcium phosphate was ex- cluded from II.
