“…Teak (Tectona grandis L.f) is a highly valued tropical timber species that is widely grown in regions within its native habitat in Southeast Asia, specifically India, Laos, Myanmar, and Thailand, as well as in Latin America, Africa, and Oceania (Gaitan-Alvarez et al 2019;Moya and Tenorio 2021;Sasidharan 2021). There has been a significant amount of research on the radial properties of teak wood, while the longitudinal variations have received relatively little attention, as recently summarized by Moya and Tenorio (2021). In the context of the above information, the growth pattens of teak in both spatial (height) and temporal (diameter/radial) dimensions are characterized jointly, i.e., the organization of growth pattens in both space and time into a hierarchical system, using tensor and vector calculus principles.…”

The space-time structure of a teak wood specific gravity (SG) dataset was analyzed using a mixed-effects model. Spatial correlation increased in space, a phenomenon attributable to the maturation of apical meristems, while the temporal correlation of vascular meristems decreased over time. The decay of temporal correlation over time was attributed to the diminishing crown effect on the later formed wood further away from the pith, morphogen gradient, and probably changing microenvironmental conditions. The Kronecker product was used to collect spatiotemporal data on the intricate dynamic process of the evolution of the apical and lateral meristems. The results showed that height and relative radial distance (RRD) (i.e., the flow of time with wood formation) were statistically significant factors, with their interaction showing no significance. The results confirm the usefulness of using the space-time approach to elucidate the interaction between the apical and lateral meristems, two major inherent biological systems that control tree growth and wood formation dynamics. To understand the origins of patterns that vary both temporally and spatially in the tree, future work should describe the variation of SG within the tree due to increasing height (space) and diameter (age) as a matrix; then the correlation function can be modelled.
