Slowing of Spore Germination with Changes Between Moderately Warm and Cool Temperatures. Paul E. Waggoner, The Connecticut Agricultural Experiment Station, New Haven 06504; Jean-Yves Parlange, The Connecticut Agricultural Experiment Station, New Haven 06504. Phytopathology 65:551-553.

Although Alternaria solani spores germinated with equal rapidity at 16 or 35 C, frequent changes from 16 to 35 C more than doubled the germination time. We infer that germination follows different paths at 16 and 35 C and that changing paths slows germination.
