Some Effects of Artificial Defoliation on Pine and Larch
Abstract:In the spring of 1924 the writer, with the assistance of R. A. St. George, undertook an experiment to determine the effects of a series of artificial defoliations on a group of some 90 pine and latch trees set out at East Falls Church, Va., in 1915. When the stand was removed, early in 1930, it became necessary to discontinue the work, but it seems worth-while to put on record what was done and the effects observed even though the results were not so complete as desired.
