| Abstract/Contents: | Presents the results of a study in which researchers "observed [that] natural branching angles which establish branch geometry are very similar to theoretical angles which produce the maximum effective leaf area...[and] branching geometry of real herbs influence the effective leaf surface through the theoretical study of terminal branching growth." Details methods and materials used in the study, stating that researchers "presented branching patterns of the spreading herbs...through top view of a photographic branch tier and computer simulated one." Explains that "branching angles were measured directly, using a protractor. Those field data were compared to the positive feedback system model." Reports that "in the case of herbs, it is simplified in two dimension, because that the spreading herbs is considered as two dimensional canopy shape...Optimal branching angles can be varied with tier symmetry of the plant, optimal of branch complexes in a tier (completely of the daughter branch), relative size of leaf cluster, and the ratio of branch units in real plant." Concludes that "two aspects of herbaceous architecture on morphological bases are distinguished into deterministic architecture and opportunistic architecture. Both aspects are expressed by environmental and genetical interactions with herbs. A herb's morphology is consequence of these interactions. The deterministic architecture is the genetic information of the individual which is typically most clearly seen in the phenotypes. The opportunistic architecture is the sum of modifications according to the herb's response to its environment...The shapes of herbs and the arrangements of their leaves have been related to the adaptive importance of light interception by the leaf surface. Therfore [therefore], those simulations for canopy architecture of plants are also useful in designing the maximizing effective leaf area, sunlight interception, photosynthesis and matter production." |
