Abstract:Early studies of seed production by the various conifers of the Central Rocky Mountains gave rise to the theory that weather conditions at the time of flowering play a significant role in the biology of these species just as it does in the case of fruit crops. In order to obtain definite information in support or contradiction of this theory a study was undertaken with Douglas fir as the test species.
