A living wood fiber (LWF) is one that retains the living protoplast. LWFs store numerous starch grains during the dormant period. In black locust (Robinia pseudoacacia), almost all wood fibers in the outer part of the annual ring are LWFs. In the outermost ring, starch is accumulated during the summer, retained in winter, and metabolized during spring. We determined the starch content of LWFs, ray parenchyma, and axial parenchyma using image analysis. More than 70% of the starch grains in the outermost ring were stored in LWFs during winter. After the breakdown of starch in spring, LWFs resulted in cell death. These results indicate that LWFs in black locust function as single-use large-capacity starch storage.
