Resumo: | Production and physical and chemical characteristics of four cultivars (IAC-4, Brune Vermelha, Riverside Vermelha and Pirassununga Vermelha) and two selections of guava (Psidium guajava L.) (RBS-1 and RBS-2) were studied in 1993 and 1994 crops, in Porto Lucena, State of Rio Grande do Sul, Brazil, in a subtropical region. The design was in randomized blocks with four replications. The production ranged from 22.05 t/ha (RBS-1 selection) to 29.96 t/ha (cv. Brune Vermelha) in 1993, and from 13.65 t/ha (RBS-2 selection) to 27.34 t/ha (cv. Pirassununga Vermelha) in 1994. RBS-1 selection showed the longest longitudinal and transversal diameters and the heaviest and thickest pulp. Cultivars and selections did not present any significant difference in regard to titratable acidity (TA), pH, total soluble solid (TSS) and TSS/TA relation. Pectin content was higher in Riverside Vermelha with 1.51% and cv. IAC-4 in vitamin C contents with 179 mg of ascorbic acid/100 g of fruit. |

Estudaram-se a produção e as características físico-químicas dos frutos de quatro cultivares (IAC-4, Brune Vermelha, Riverside Vermelha e Pirassununga Vermelha) e duas seleções (RBS-1 e RBS-2) de goiabeira (Psidium guajava L.), na 5a e 6a colheita (1993 e 1994), em Porto Lucena, RS, local de clima subtropical. O delineamento experimental utilizado foi o de blocos casualizados, com quatro repetições. Em 1993 as produções variaram entre 22,05 t/ha (seleção RBS-1) e 29,96 t/ha (cv. Brune Vermelha), e em 1994 entre 13,65 t/ha (seleção RBS-2) e 27,34 t/ha (cv. Pirassununga Vermelha). Ocorreu uma tendência de redução do peso médio dos frutos com o aumento do número de frutos por planta. A seleção RBS-1 apresentou o maior peso e espessura de polpa e maiores diâmetros longitudinal e transversal. As cultivares e seleções não apresentaram diferenças significativas quanto a acidez titulável (AT), pH, sólidos solúveis totais (SST) e relação SST/AT. A cultivar Riverside Vermelha destacou-se no teor de pectina, com 1,51%, e a IAC-4 nos teores de vitamina C, com 179 mg de ácido ascórbico por 100 g de fruto.
