| description | Climate change and its variability increase rainy periods, generating flooding and waterlogging, which affect the physiological development of cultivated species. In lulo, although growth under shade is recommended, the effect of stress due to waterlogging was studied under conditions of partial shading in greenhouse. Young lulo plants were planted in 5 L plastic pots with soil and sand quartzite at a ratio of 1: 1 v/v as substrate. The effect of 65% shading and no shading during four periods of waterlogging, 0, 3, 6 and 9 days, and a recovery period of 9 days each on the development of plant biomass and roots was determined. The shading decreased biomass accumulation in all of the vegetative organs, especially the leaves (-22.7%). No interactions between the shading and waterlogging were measured. The root system proved to be the organ most affected by the periods of increased waterlogging (over 6 and 9 days), with reductions in the diameter of the root collar, length of taproot, volume and dry weight of roots, while; as a consequence, the shoot/root ratio of the biomass increased due to rhizosphere oxygen deprivation. During the recovery period of 9 days, the negative effect of the waterlogging persisted and was further aggravated for the volume and root length variables. |

El cambio y la variabilidad climática incrementan los periodos de lluvias, generando inundaciones y/o anegamientos, los cuales impactan en el desarrollo fisiológico de las especies cultivadas. En lulo, aunque se recomienda su siembra bajo penumbra, se estudió el efecto del estrés por anegamiento en condiciones de sombrío bajo invernadero. Las plantas de lulo, de 10 semanas de edad, fueron sembradas en materas de plástico de 5 L con un sustrato suelo y arena cuarcítica en proporción 1:1 v/v, se determinó el efecto de 65% sombrío en los cuatro periodos del anegamiento de 0, 3, 6 y 9 días, más 9 días de recuperación c/u, sobre el desarrollo de la biomasa de planta y las raíces. El sombrío disminuyó la acumulación de biomasa en todos los órganos vegetativos, especialmente en las hojas (-22,7%). No se presentaron interacciones entre el sombrío y el anegamiento. La raíz resultó ser el órgano más afectado por los periodos de mayor anegamiento (6 y 9 días), con reducciones del diámetro del cuello radical, longitud de raíz pivotante y del volumen y peso seco de raíz, mientras que, en consecuencia, la relación de biomasa entre la parte aérea y la raíz se aumentó. Durante el periodo de recuperación de 9 días persistió el efecto negativo de la privación del oxígeno en la rizósfera y, más bien, se agravó todavía más para los variables volumen y longitud de la raíz.
