Phenodynamics of production and chemical pools in mayapple and flowering dogwood
The objective of this study is to provide an understanding of the seasonality of biomass production and chemical storage among selected forest species as an aid to the analysis and management of a forest ecosystem model. The specific goals to accomplish the objectives included: (1) the construction of phenological calendars to be superimposed on the civil calendar, such that the seasons of the year are not marked by calendar dates but rather by dated groups of phenological events; (2) to develop a capability to predict onset of the generative phase (flowering) from heat unit summation methods; (3) to illustrate the role of phenology to biomass production and chemical storage in two indicator species, mayapple and flowering dogwood; and (4) to develop the capability to predict aboveground and below ground standing crop biomass in dogwood. Observations in this study focused on the generative phases (flowering) of individual plants and colonies of plants as indicators of productivity. 16 figs., 11 tabs.
