Is there any articles establishing authentic and easy methods by which form factor of the tree bole can be measured using height, DBH or sectional diameter? Pls provide with citations.
Perhalps this could help

Procedures for determining form factor from tree height & girth/dia meter measurements are available in any standard book on Forest Mensuration.
But of course, i probably misses the environmental conditions of forming the free form, what ever they might be, of natural or antropic nature...
please refers this paper you will get your answer ...my publication is in press ..it will come online in short while i will send you.
Form factor is ratio of tree real volume to volume of one geometrical form such as cylinder. Form factor is one method for harmony and relation between tree form and volume. Form factor is calculable for all of trees (stems and branches) and/ or for tree stem. You may refer to forestry books like Avery & Burkhart (1994), Philip (1994), Van Laar and Acka (1997) and many others.
yes. see this article.
((Estimating tree volume using a new form factor
Author(s): JOSÉ A. ALEIXO DA SILVA, BRUCE E. BORDERS and GRAHAM H. BRISTER Source: The Commonwealth Forestry Review, Vol. 73, No. 1 (1994), pp. 14-17))
This estimator could be useful in forest inventories for species which do not express
significant butt swell, and could obviate the need for specific volume equatio
