....been postulated, but it is convenient to capture their average outcome rather than the details of operation in models constructed at a high level of abstraction. For example, several plausible mechanisms for preventing the overcrowding of branches in a tree have been described in the literature [8, 51], yet a statistical model that captures the density of branches without simulating the controlling processes is also useful (Sections 5.3 and 8.3.2) Several stochastic extensions of L systems have been proposed in the literature [21, 56, 87, 133] and applied to express developmental plant models ....

....the amount of water and minerals absorbed by the roots and carried acropetally, and bytheamount of photosynthates produced by the leaves and transported basipetally. An early developmental model of branching structures making use of quantitative information flow was proposed by Borchert and Honda [8]. Below we restate the essence of this model using the formalism of L systems, then we extend it to simulate interactions between the shoot and the roots in a growing plant. Borchert and Honda postulated that the development of a branching structure is controlled byafloworflux of substances, ....

.... a formally defined framework for simulating interactive control mechanisms, and have been used for image synthesis purposes by Smith [33] and Prusinkiewicz et al. 28, 29] Outside the domain of L systems, models of interactive endogenous control have been investigated by Borchert and Honda [6]. In contrast to structure oriented models, space oriented models capture the entire environment of a growing plant, and emphasize exogenous control, in which information is transferred through the environment enclosing the modeled structure. This class includes the models of climbing plants ....

An early developmental model of branching structures making use of quantitative information flow was proposed by Borchert and Honda [52]. Below we restate the essence of this model using the formalism of L systems, then we extend it to simulate interactions between the shoot and the roots in a growing plant.

Based on [52]. Production p 7 adds the number of apices supported by the daughter branches (c 1 and c 2 ) and propagates the result to the mother internode. Both input numbers must be available (m 1 = 2 and m 2 = 2) before basipetal message propagation takes place. The remaining productions reset the ....

....In the above model, the shedding had only a limited effect on the development of the remaining parts of the tree. In nature, trees may compensate for the loss of a branch by the more vigorous growth of other branches. A model that captures this phenomenon has been proposed by Borchert and Honda [6], and is illustrated in Figure 20. In this case, basipetal signals originating at each node carry information about the size of branches. This information is used to allocate fluxes that propagate acropetally and determine the vigor of the apices. Pruning of a branch redirects the fluxes to the ....

....increase exponentially. Observations of real branching structures show, however, that the increase in the number of segments is less than exponential [8] Honda and his collaborators modeled several hypothetical mechanisms that may control the extent of branching in order to prevent overcrowding [7, 33] (see also [4] One of the models [33] supported by measurements and earlier simulations of the tropical tree Terminalia catappa [19] assumes an exogenous interaction mechanism. Terminalia branches form horizontal tiers, and the model is limited to a single tier, treated as a two dimensional ....
