RESUMOO substrato deve ser escolhido para proporcionar condições adequadas para a germinação e o desenvolvimento de plantas, garantindo o sucesso do empreendimento. Assim, objetivou-se estudar cinco substratos para germinação e produção de mudas de maracujá e mamão formosa. No experimento foram utilizados cinco tratamentos: S1; S2; S3; S4 e S5, variando entre substratos comerciais e inertes. Foram avaliados: porcentagem de emergência (E), índice de velocidade de emergência (IVE); tempo médio de emergência (TME), velocidade de emergência (V), altura de plantas aos 15 (Alt15) e 30 dias (Alt30), massa seca da parte aérea (MSPA), raiz (MSR) e total (MST), razão MSPA/MSR, comprimento da raiz (CR), diâmetro do caule (DM) e o índice de qualidade de Dickson (IQD).

This study was carried out with the objective of evaluating the water relations, photosynthetic pigments and growth of passion fruit cv. BRS Rubi do Cerrado, as a function of the cationic nature of irrigation water and exogenous application of hydrogen peroxide. The experiment was carried out under greenhouse conditions in Pombal – PB, Brazil. The experimental design was randomized blocks, in a 6 × 4 factorial scheme, corresponding to six cationic nature of water - CNW (S1 - Control; S2 - Na+; S3 - Ca2+; S4 - Na++Ca2+; S5 - Mg2+ and S6 - Na++Ca2++Mg2+) and four concentrations of hydrogen peroxide - H2O2 (0, 20, 40 and 60 μM), distributed in a randomized block design with four replicates. Plants in the control treatment (S1) were irrigated using water with electrical conductivity (ECw) of 0.3 dS m-1, while those of the other treatments (S2; S3; S4; S5 and S6) were subjected to ECw of 3.0 dS m-1, prepared with different cation(s). Application of 60 μM of H2O2 reduced the percentage of intercellular electrolyte leakage in plants irrigated with water of calcic composition. Salinity of water composed of sodium, sodium+calcium and sodium+calcium+magnesium, and H2O2 concentrations of 40 and 60 μM resulted in lower leaf water potential. The biomass accumulation of passion fruit was more sensitive to the variation of the electrical conductivity of the water. Regardless of the cationic nature, the use of water with electrical conductivity of 3.0 dS m-1 produced passion fruit seedlings with a Dickson quality index higher than 0.2, considered acceptable.

Conotelus sp. (Coleoptera: Nitidulidae) is a substantial pest of passion fruit production in the Zona da Mata region of Rondônia, Brazil, making this agricultural activity unviable. This study evaluated the toxicity of registered and unregistered chemical insecticides for passion fruit cultivation against Conotelus sp. under laboratory conditions. Eight insecticides were evaluated at recommended field application concentrations. Passion fruit flowers sepals were immersed in insecticide solutions, and five larvae measuring 2 to 3 mm were placed on these sepals. Additionally, LC50 and LC90 values were determined for the insecticides fenpropathrin and chlorpyrifos. The results showed that chlorpyrifos, fenpropathrin, spinetoram, imidacloprid, chlorfenapyr, and thiamethoxam were effective in controlling Conotelus sp. larvae, demonstrating their potential for managing this insect pest. The LC50 values of chlorpyrifos and fenpropathrin for Conotelus sp. were 3.19 g a.i./100 L and 22.09 g a.i./100 L, respectively, showing the higher toxicity of chlorpyrifos. The estimated LC90 values for chlorpyrifos and fenpropathrin are 8.36 g a.i./100 L and 79.04 g a.i./100 L, respectively. These findings strengthen the scientific basis for selection and implementation of management measures to control Conotelus sp. in passion fruit plantations.
