Evaluación de métodos de escarificación y sustrato para Prunus serotina para la conservación de la agrobiodiversidad en los andes centrales del Ecuador

Abstract

The objective of the research was to perform an evaluation of the scarification methods and substrates for the species Prunus serotina subsp capulí, taking samples in the provinces of Chimborazo, Tungurahua and Cotopaxi, to measure the most outstanding germination percentage, using the Statistical Design, Bifactorial DCA, 3 scarification methods and 4 combinations of substrates were used, each with different percentages of combinations, obtaining 12 treatments where each has 3 repetitions of 10 units, generating 360 experimental units. The results indicate that the combination of the scarification method E2: Immersion of the seeds in water at room temperature, with diluted biol (for each liter of water there are 33 ml of biol) for 7 days, daily change of water, once the seeds have been soaked for 7 days they are drained and placed in the refrigerator at 0 ° C for 60 days. (Cold Hours Scarification), with the S3 substrate: 75% Black Earth and 25% Sand are the best combination in terms of generating capulí seedlings, obtaining 96.67%, in turn, secondary research was generated that provided us with information to generate a conservation proposal in situ and ex situ for the Capulí, being able to obtain main ideas such as the generation of seed storage with good genetic variability, in vitro seedling conservation and generate campaigns on awareness of the benefits of the capulí, both the plant and its fruit.
