| Descripción: | Introduction. Wild species are important in the ecosystem, these require the development of techniques that allow their preservation. Objective. Determine the characteristics of in situ and ex situ germination and field growth of the species Porcelia mediocris N.A. Murray and Compsoneura trianae Warb. in Arosemena Tola, Napo, Ecuador. Materials and methods. The study was carried out between 2019 and 2020, seeds were collected in the primary forest of P. mediocris and C. trianae. Germination tests were developed in a greenhouse and in primary forest, seed emergence and tray growth were measured and an analysis of variance was applied between the test sites. The seedlings were transplanted in three different soil covers at the Amazon Teaching, Research and Productivity Center, measurements of growth in height, stem diameter, number of leaves and survival were taken, growth curves were prepared and an analysis of variance in the final growth measurements between the different coverages. Results. In P. mediocris, the plants grown in the greenhouse reported fewer days to the emergency (67.6), but the plants grown in the guabas coverage had a greater height (19.45 cm) and germination percentage (70 %) at end of the test. In C. trianae, the plants developed at the collection site had greater height (13.38 cm) and number of leaves at the end of the evaluation. In field growth, no differences were reported between the different coverages, reaching a survival of 47 % in P mediocriss and 75 % in C. trianae. Conclusions. In germination, P. mediocris reported better germination percentages in the guabas coverage and C. trianae had greater growth in the primary forest, without the germination site influencing the growth after transplantation in both species. |
