| Outline of Final Research Achievements |
Under the low-light condition, Thujopsis dolabrata var. hondae (hiba) could make layering with several branches and each layered branch could stand independent from the non-photosynthetic tissue behind the adventitious root. We assumed that this is a regeneration strategy of increasing the number of ramet, and occupying space horizontally. We set up an experimental plot in place where hiba sustained seedling bank over 80 years under the beech forest canopy. We carried out DNA analyses to identify individual and tree-ring analysis to elucidate the age of several ramets. As a result, it was revealed that hiba increased the number of stems in a shrub-like manner by layering, occupied space horizontally, and there were trunks surviving for 90 years under the beech forest canopy.
