Biomass allocation between lamina and petioles in a game of light competition in a dense annual plant stand

Plant architecture is important for light capture. In the field, plants compete with neighbours for light. In a competing system, game theory is needed to consider advantageous strategy (evolutionarily stable strategy; ESS). Yoshinaka et al. focus on a trade-off between lamina area and petiole length and analyse an evolutionarily stable petiole length in stands of Xanthium canadense (Asteraceae) using a simulation model YPLANT. They find that there are multiple evolutionarily stable petiole lengths even in one stand, suggesting that plants with different architectures can coexist across plant communities. The mean of evolutionarily stable petiole length was similar to the real...

Leaf display by conifer and angiosperm seedlings

Leaf display by conifer and angiosperm seedlings

The contemporary relegation of conifers mainly to cold or infertile sites has been ascribed to low competitive ability. Lusk et al. use 3-D modelling of plant architecture and structural equation modelling to compare self-shading and light interception potential of seedlings of six conifers and 12 angiosperm trees from temperate rainforests, and show that seedlings of conifers display only about half the effective leaf area of their angiosperm competitors, due to differences in specific leaf area, biomass distribution, leaf angles and self-shading. The superior light interception potential of angiosperm seedlings therefore probably contributes to the success of this lineage in productive environments...
