INOCULATION EXPERIMENTS. 79 



BEAN TO PUMPKIN. 



A mature pumpkin was inoculated by puncture with conidia from 

 a culture from bean. No signs of infection followed. 



BEAN TO HUBBARD SQUASH. 



A mature squash was inoculated by puncture with conidia from a 

 culture of the bean Glomerella. No decay followed and no acervuli 

 formed. 



BEAN TO TOMATO. 



Four green tomato fruits were inoculated by puncture with conidia 

 from wax beans. No decay followed and no acervuli formed. 



BEAN TO WATERMELON. 



A nearly mature watermelon was inoculated by puncture with 

 conidia from a bean culture. No signs of infection followed. 



It will be observed that no successful inoculations from bean to 

 cucurbits were made. These results agree with those of Edgerton 

 (30) but not with those of Halsted (39). 



CAMELLIA TO BEAN. 



On June 4 five young pods of bean grown in the greenhouse were 

 inoculated by surface application of conidia in sterile water. No 

 signs of infection followed. 



On June 5 the same experiment was repeated with six pods, but 

 without success. 



CARYOTA TO COTTON. 



On April 1 stigmas of three cotton flowers were inoculated by apply- 

 ing conidia in sterile water to the surface. The young bolls soon 

 dropped, but when placed in moist chamber no conidia developed. 



CHERIMOYA TO APPLE. 



On October 2 three apples were inoculated by puncture with 

 conidia from a culture. Decay followed about the points of inocula- 

 tion in one week and acervuli were produced. 



CHERIMOYA TO GRAPE. 



On October 4 eight mature berries were inoculated by puncture 

 with conidia from a culture. At the end of two weeks all the granes 

 were decayed and seven showed acervuli.
