Las Naciones Unidas declararon el año 2021 como el Año Internacional de las Frutas y Verduras. Agrociencia Uruguay consideró oportuna la edición de un número especial conmemorando esta iniciativa y contribuyendo a la difusión de información científica sobre el aporte de estos cultivos y alimentos

ABSTRACT.- The expansion of olive orchards into regions with no tradition of olive production and humid climates, such as Uruguay, with more than 1200 mm of annual rainfall, calls into question the need for irrigation. In these regions, however, years with water deficit during summers are quite common. The vapor pressure deficit during summer is lower than in countries with a Mediterranean climate.

ABSTRACT.- Diversification of rootstock varieties, with consequent reduction in phytosanitary risks, has great importance to the sustainability of citrus cultivation in the south of Brazil. This study evaluated the performance of 42 rootstocks in the nursery phase to generate ?Valencia Late? sweet orange seedlings. Therefore, nucellar seedlings from the rootstocks under study were analyzed in relation to plant height, stem diameter, mortality rate and percentage of bud set after grafting. The experimental design was completely randomized with four replications of 20 sample units.

ABSTRACT.- The adaptation of temperate fruit crops is a challenge being increased by the global warming. Chilling requirement is a key factor for adaptation. The objective of this study was to estimate the chilling requirement of peach cultivars BRS Bonão, Esmeralda, Granada and Eragil, using the Tabuenca test. Chilling accumulation was computed using four different chilling hour (? 7.2 ºC and ? 11 ºC) models; and chill units using the Low Chill model and the Taiwan model. The fresh bud weight and bud water contents were also evaluated.

El objetivo de esta presentación es resumir las experiencias realizadas hasta el momento y describir las diferentes etapas del proceso de estaquillado semi-leñoso del guayabo del país en busca de obtener mayores porcentajes de enraizamiento.

Com este estudo objetivou-se avaliar características fitoquímicas de 12 genótipos de araçá amarelo oriundos de populações espontâneas do Rio Grande do Sul.

Neste resumo, serão destacados dois destes trabalhos, um sobre estrutura populacional de sete jaboticabais (Moura, 2017) e outro sobre diversidade genética por marcadores moleculares em seis jaboticabais (Salla, 2019).

Hay un creciente interés en la región por los frutales nativos y sus posibles usos. Trabajos realizados en Brasil y Uruguay destacan las buenas cualidades de los frutos de Eugenia involucrata para su consumo en fresco e industrialización.
