Function of xylem rays
WebApr 29, 2024 · The radial movement of minerals in tree trunks is a widely accepted function of ray parenchyma cells, but there is little experimental evidence for this. We previously obtained experimental data showing that the parenchyma cells were the site of the radial mineral movement in Japanese cedar (Cryptomeria japonica D. Don) trunks in winter. … WebThe rays in the secondary xylem and phloem are produced by periclinal divisions of ray cell initials of the cambium. Ray development involves periodic changes in their number, height, and width as the tree grows. Most new rays form in very young trees when peripheral expansion of the cambium is maximal.
