In order to contribute to greater market transparency, APFC - Associação de Produtores Florestais, conducts an impartial sampling and issues since 2015 a press release on pine cone average yields in the Coruche region (Portugal).
For the fifth consecutive year, APFC has used a methodology for sampling the cone quality at 8 sites throughout the municipality of Coruche in order to represent the entire area of pine production.
Each sample has 10 cones harvested randomly from each of 30 trees per site. The cones are weighted before opening, the inshell pine nuts are removed mechanically and shelled manually (sample of 2 kg). The kernels are weighed at a reference humidity (9%) and referred to the cone weight.
The objective is to analyze the possibility of modeling the kernel weight from biometric and morphological parameters of the pine nuts from Pinus pinea, measured through X – ray and image analysis. The overall objective is to support the definition of a pine cone quality assessment methodology at the stand/ farm level in order to provide the landowners with tools for pine cone commercialization and increase by this mean the market transparency.
