The hard pheripheral region of the stem is only 0.5 to 5.2 cm in thickness or 4 to 20 percent of the .stem volume.The pheripheral region of the stem consists largerly of fibrouascular bundles while the central portion consists mainly bf parenchyma tissues. The frequency of vascular bundles at pheripheral region may reach 139 bundle/sq. cm then gradually decreased to 10 bundles/sq. cm at the center.The fiber dimension vary along and across the stem: length 1618 to 2712 microns, diameter.28 to 52 microns, wallthickness 5 to 24 microns.
