The objective of the study was to determine the allometric model that best fits the diameter - commercial height relationship in Pouteria cake (Mart.) Radlk “quinilla” trees in natural forest according to sample type. Puerto Almendra, Loreto, Peru – 2023. The variables used were diameter and commercial height of trees with DAP ≥ 10 cm; 4 samples were used, sample 1 was 5 diameter classes with 40 individuals; sample 2 with 9 diameter classes and 40 individuals; sample 3 with 20 individuals chosen at random and sample 4 was the representative sample with 30 individuals chosen at random. The results indicate that the Inverse allometric model was the one that presented the best relationship between diameter and commercial height in the samples evaluated for Pouteria cake (Mart.) Radlk “quinilla” trees in natural forest; Furthermore, it was determined that the degree of relationsh...
