dc.description	Mortiño (Vaccinium floribundum), are fruits in the form of blue berries, natives of he Andean moors, of great importance for their properties nutritional and its high antioxidant content. Currently, this species is is at risk of extinction due to the burning of moors, the expansion of the agricultural and livestock frontier causing genetic erosion of the species. For this reason conservation methods are being sought, and been able to demonstrate that the production of plants from in vitro seeds is an alternative to maintain its genetic characteristics throughout the time, therefore, this study aims to assess the physical quality and physiological of the seed, in order to produce seedlings in vitro. The study was carried out with a Completely Random Block Design (DBCA) in factorial arrangement 2 by 8 with 3 repetitions. The factor 1) fruit size (large, greater than 6 mm and small, smaller than 6 mm), and 2) storage at 4 degree celsius for 120 days, with evaluations every 15 d. The variables studied were germination, germination speed, length of seedlings, root number, abnormal seedlings, weight of 100 seeds, empty seeds. The fruits were collected in Pueblo Viejo, province of Carchi. The fruits were sorted, and the seeds were extracted, impurities were removed, disinfected and stored at 4 degree celsius for 120 days. Germination was carried out in a growth chamber at 18 degree celsius, 90 percent relative humidity and 24 hours light. Demonstrating in its results that there are highly significant differences between variable and factors, where the best treatment for the first factor (fruit size) was f1 (large fruit), as it presented higher percentage of germination, seedlings with greater length and number of roots, greater weight in 100 seeds, less vain seeds and more viable. For the factor 2 (storage time), the best treatment was A1 (15 d), where, like the size of the fruit, higher values were obtained with respect to most variables.	en
