Outline of Final Research Achievements

Plants change their body sizes in response to mechanical stress (MS) such as trampling. During the process of decrease/increase of plant body size in response to the application/elimination of MS, nitrogen within the plant body might be concentrated/diluted accordingly, which, in turn, result in lower/higher photosynthetic potentials. Such a “chain reaction” appeared to be more popular among perennial clonal plants and relatively rare among plants with high MS sensitivity.
Under MS, photosynthetic production of a plant/stand as a whole declines as a result of miniaturization. However, increase in photosynthetic potential per area resulting from nitrogen enrichment should partly compensate for the reductions in the total photosynthetic productivity. Moreover, the MS-induced miniaturization was found to increase survivability of plants dramatically under certain circumstances.
