Relationships among Anatomical Characteristics of Nine Japanese Angiosperm Trees without G-Fiber in Reaction Wood
Journal Title: Journal of Plant Science and Research - Year 2018, Vol 5, Issue 1
Abstract
The relationships among the anatomical features in reaction wood of nine Japanese hardwood species without G-fiber were studied. Leaning branches of nine naturally growing species were examined: Euscaphis japonica, Viburnum dilatatum, Rhododendron wadanum, Enkianthus subsessilis, Euonymus alatus, Ilex macropoda, Ilex crenata, Clerodendrum trichotomum and Daphne odora. As complementary characteristics of the previous report in these nine species, the changes in vessel diameter, vessel length, fiber diameter, cell wall thickness of fiber, fiber length, and Microfibril Angle (MFA) of the S2 layer in wood fiber were examined in reaction wood in comparison with opposite wood. Depending on the species during reaction wood formation, the vessel and fiber characteristics in reaction wood were significantly altered. A significant negative correlation (0.635, p ≤ 0.05) was observed between eccentric growth and the rate of increase in the fiber wall thickness. On the other hand, the decrease rate (DR) of the lignin content was significantly correlated to the DR of the vessel number (0.869, p ≤ 0.01).
