espanolLa uchuva (Physalis peruviana L.) es una solanacea susceptible a enfermedades del suelo, por esa razon se propone su cultivo en Mexico bajo invernadero e hidroponia. Es necesario, determinar su respuesta a la conductividad electrica de la solucion nutritiva (CE), razon por la cual se expuso a las plantas a 1, 2 y 3 dS m-1. La luz solar es otro factor que incide en la calidad de los frutos, por lo cual se cosecharon frutos del interior y exterior del dosel vegetal. Tambien se determino el efecto de la madurez del fruto. A los frutos se les determino peso, Brix, firmeza y color (L, a y b). La CE, ubicacion en dosel y madurez de frutos generaron 12 tratamientos. Los datos se compararon con prueba de medias de rangos. De los frutos, la CE de la solucion nutritiva afecto la firmeza y los Brix excepto el peso. La posicion de los frutos en el dosel vegetal tampoco afecto estas variables. La madurez a la cosecha afecto la calidad de los frutos. Los frutos cosechados 30 dias despues de madurez comercial perdieron peso y firmeza, y aumentaron Brix en frutos mas maduros. La ubicacion del fruto y madurez no afectaron el color en fruto EnglishThe cape gooseberry (Physalis peruvianaL.) is a nightshade susceptible to soil diseases, for this reason it is proposed to grow it in Mexico under greenhouse and hydroponics. It is necessary to determine its response to the electrical conductivity of the nutrient solution (EC), which is why plants were exposed to 1, 2 and 3 dS m-1. Sunlight is another factor that affects the quality of the fruits, for which fruits were harvested from inside and outside the plant canopy. The effect of fruit maturity was also determined. The fruits were determined weight, Brix, firmness and color (L, a and b). The EC, location in canopy and fruit maturity generated 12 treatments. The data were compared with a range mean test. Of the fruits, the EC of the nutritive solution affected the firmness and the Brix exceptthe weight. The position of the fruits in the canopy did not affect these variables either. The maturity at harvest affected the quality of the fruits. The fruits harvested 30 days after commercial maturity lost weight and firmness, and increased Brix in more mature fruits. Fruit location and maturity did not affect fruit color
