Effect of Diluents on Conidial Germination of Macrosporium 

 Sarcinaeforme 



Error of the mean*: cheek, 98.0 ±0.02; lime, 94.9 ±0.91; talc, 95 ± 0.07 and bentonite, 98.1 ±0.01. 

 Error of the difference: check and lime, 3.05 ± 0.91; check and talc, 2.60 ± 0.07; check and bentonite, 

 0.14 ± 0.02. 



* The probable error of the mean in this bulletin has been calculated according to Bessel's formula: 

 = 0.6745 JE (v-g)s ~

for twenty-four hours, and then were transferred to a greenhouse bench 

 until data were taken. The results of two experiments, one conducted 

 in the spring and one in the fall, are given in table 10.
