Annual Bud Set and Production at Badger and Midwest marshes, 1941-1946. the few in the state extensively damaged in 1946. 205 random fruit buds collected on the latter marsh on May 31, from two sec- tions that later proved to have less than the average amount of injury, were dissected and examined for injury with the following results; buds dead, 12 (5'/J); buds with one or more flower initials dead, 75 (35Tf); buds apparently uninjured, 120 (580-,). 1945 bloom was judged to have been about equally heavy on the two marshes, i. e., the injury at Biron did not greatly reduce the numbers of flowers. Differences in set, however, resulted in widely different yields: barrels per acre at Biron, barrels at Cran- berry Lake. The 1946 injury at Cranberry Lake reduced both the numbers of uprights that bloomed and the numbers of blossoms per upright; and as the blossoming season extended over a long per- iod, the numbers of flowers in bloom at any given time were un- believably small. The percentage set was phenomenally high, how- ever, a circumstance that will be discussed later, and resulted in a yield of barrels per acre; the Biron marsh yielded barrels per acre. Fruit set counts on the 2 marsh- es, made by the method described elsewhere (1), are given in table 2. The sample counts brought out the differences in type of injury with great clarity. That the widespread failure in set in 1945 was the direct result of water injury was evident from three facts: 1. It occurred on marshes which were flooded for long periods in April and May, but was absent on nearby marshes which were not subjected to long floods. 2. Unmistakable forms of water injury occurred locally throughout marshes that failed to set properly. 3. Similar failure to set was experienced on 2 marshes where oxygen-tests were run, in locations where oxygen content dropped too low befor
