The dynamic of an exponential decline in bud opening as pods increase was
incorporated into a model of alfalfa pollination.
The model (Strickler 1996, 1997) was based on information in the literature
and conversations with other researchers and growers. It was aimed not at
predicting but at understanding interactions between components of the system
in ways that would be difficult or impossible to test in the field. Modeling
helps to identify gaps in our knowledge of the alfalfa seed system. It also
stimulates an exploration of the hypotheses that are made to generate the
(This is a relatively simple and explanatory model, but if models intimidate
you, skip to model insights)
