7. Selection 202 inoculated at blossoming time, and therefore with 



mycelium in the pericarp (possibly some ungerminated spores 

 present ) . 



8. Selection 202 dusted with spores after harvest, and therefore with 



ungerminated spores on the pericarp. 

 Experiments and results 



Early in June, 1926, the variously treated supplies of seed, both those 

 inoculated with U. avenae spores and those inoculated with U. h vis 

 spores, were sown in the greenhouse under conditions favorable for the 

 growth and development of oats. Both pots and flats were used. All 

 seed was planted approximately 1^ inches deep, and all plantings re- 

 ceived frequent watering. Under these conditions and the high tem- 

 peratures of the greenhouse in July, the plants began to head out in 

 early August. The results are given in tables 2 and 3.
