Los dos tamaños de la semilla se obtuvieron mediante tamizado, a partir de frutos clasificados por sanidad y peso: 1,107 y 0,916 mg, que resultaron en un 100% de germinación en laboratorio. En invernadero se sembraron las uchuvas en seis sustratos: fibra de coco brasilera (FCB), arena lavada de río fina (ALR), turba alemana rubia (TAR), turba canadiense con perlita (TCP), mezcla de turbaalemana rubia con cascarillade arroz 50:50 (TAR+C) y una mezcla de fibra de coco brasilera con cascarilla de arroz 50:50 (FCB+C). Se evaluó emergencia, altura, número y área de hojas, masa seca de la parte aérea y volumen de raíces de las plántulas en invernadero. La FCB presentó los valores más altos para altura y número de hojas, mientras este sustrato y la TAR indujeron la mayor área foliar y masa seca de la plántula. El volumen de raíz fue promovido en todos los sustratos del estudio que contuvieron turba, y también en la FCB. En la ALR se registraron los resultados más bajos para todas las variables, especialmente en el desarrollo radical. Las semillas más grandes (1,107 mg) produjeron la mayor biomasa seca de la parte aérea de la plántula. RESUMEN 154 ABSTRACTThe emergence of two seed sizes of the cape gooseberry for obtaining seedlings was evaluated. The plants were cultivated in a greenhouse using different substrates with egg flats, under commercial production conditions. The two seed sizes were sieved from fruits classified by health and weight: 1.107 and 0.916 mg, which had 100% germination in the laboratory. In the greenhouse, the cape gooseberry seedlings were planted in six substrates: Brazilian coco peat (BCP), fine river sand (FRS), German blond peat moss (GBP), Canadian peat moss with perlite (CPP), a mix of German blond peat moss with rice hulls 50:50 (GBP+R) and a mix of coco peat and rice hulls 50:50 (BCP+R). This study evaluated emergence, height, leaf area and number, dry matter of the aerial plant part and root volume of the seedlings in the greenhouse. The BCP substrate produced the highest values for seedling height and leaf number; and also, along with GBP, induced the highest leaf area and plant dry matter. Root volume was promoted in all substrates which contained peat moss and in BCP. In FRS, the lowest values in all variables were measured, especially in root development. The biggest seeds (1.107 mg) produced the majority of their dry biomass from the aerial part of the seedling.
