I would like to show you an Embothrium coccineum woody genet
Translocation of resources among ramets of clonal plants improves population persistence, colonization, and the physiological status. Plant clonality is a promising method vastly studied and applied in herbaceous plants. However, there are few studies focused on clonal trees, mainly because the lack of studies testing the effect of environmental heterogeneity, size and source-sink relationship within a woody genet. An important information required for the assessment of this method. The main objective of this research is to characterize the distribution and interconnections of Embothrium coccineum (Proteaceae) ramets in relation to the parental tree, the allometry of the individuals and the environmental variability in which they are found. In order to do this, an entire genet of Embothrium coccineum was identified, mapped, and measured. Our preliminary results shows that ramets occupy similar canopy openness (CO) than that of the forest, with most of them (55.2%) growing at similar CO than the origin of parent tree trunk (PTT). Ramets can be found between 1 and 13 meters from the PTT base, occurring most of them to the north-west. After ramet selection according to CO and size (2 levels each), those greater ramets inhabiting higher CO show higher total leaf area (LAT) and root distal to proximal ratio (DPR). LAT is positively and significantly correlated with CO, size and DPR. The greatest investment in biomass is seen in the larger ramets at higher CO.
