“…Growth can be characterized by the growth tensor field [Hejnowicz and Romberger 1984], which specifies the magnitude of the expansion of infinitesimal surface regions in various directions, and may include a possible rotation of each region. The growth tensor is a generalization of the relative elementary rate of growth (RERG), which is defined as the rate at which an infinitesimal distance ∆s, measured in the direction of a line l at a point p of a growing object, increases over time.…”

“…1l). Inclined cell walls have been reported in LR primordia of radish [9] in which oblique divisions at early stages led to formation of cuneiform cells, and in Arabidopsis [6], in which such walls were interpreted as a manifestation of a change of the principal directions of growth (PDG) [10] within the de novo formed meristem.…”

“…The relative elementary growth rate RERG l(ζ) is the rate at which an infinitesimal distance Δζ, measured in the direction of growth line at a point on growing silhouette, increases over time. RERG is mathematically defined as [Hejnowicz and Romberger 1984]:…”

“…In this paper we will character the growth by growth tensor field at X and Y and Z coordinates [Hejnowicz and Romberger 1984;Nebelsick et al 2001;E et al 2004]. The growth tensor allows full characterization of the rate of growth in length, area, and volume, as well as rates of angular change between elements, and of vorticity in the growing organ.…”
