| ABSTRACT: The use of pesticide mixtures constitutes a relatively common practice in rice crops. Thus, the aim of this work was to evaluate the physicochemical interaction among different pesticide tank mixes for use in paddy field rice. The study has followed technical standards specified in ABNT [Associação Brasileira de Normas Técnicas (Brazilian National Standards Organization)] NBR [Norma Brasileira Regulamentadora (Brazilian Regulatory Standard)] NBR 13875:2014 for the assessment of physicochemical compatibility by means of a dynamic technique. Treatments consisted of mixtures of 12 pesticides, which constituted 16 treatments, six of which are composed by mixing herbicides, six by mixing herbicide and insecticide, one by mixing fungicides, and three... |

| Foram investigadas a biologia reprodutiva e a polinização de Erythroxylum campestre St. Hil., E. suberosum St. Hil. e E. tortuosum Mart., ocorrentes na Fazenda Água Limpa, Brasília, DF. Estas espécies são simpátricas, comumente encontradas em cerrados abertos e florescem em média quatro meses por ano. As três espécies são distílicas, isto é, apresentam flores com estiletes longos (longistiladas) e flores com estiletes curtos (brevistiladas), ambas com estames em posicionamentos correspondentes. As flores são similares, pequenas, suavemente perfumadas, de cor creme claro, diurnas, produtoras de néctar (concentração média de sacarose de 20,2%) e duram um dia. Os testes de polinização artificial revelaram que E. suberosum e E. tortuosum são auto-incompatíveis... |

| ABSTRACT: One of the biggest challenges for expansion of jabuticaba fruit tree cultivation is the high cost of seedlings due to to difficulties with vegetative propagation. Here, we aimed to evaluate graft survival in combinations of Plinia cauliflora and rootstocks of other species from the Myrtaceae family. The study was carried out at the Universidade Tecnológica Federal do Paraná - Campus Dois Vizinhos, Paraná State, Brazil. Eugenia uniflora L., E. involucrata DC, and P. cauliflora were used as rootstocks and were obtained as seeds. The 'whip-and- tongue' and cleft grafting techniques were tested for vegetative propagation. Grafted plants were cultivated in a greenhouse. The experimental design was a randomized complete block, in factorial 3×2... |
