Efeito de extratos vegetais em soja sob condições de laboratório e campo.
Provedor de dados: Organic Eprints
Autores: Gouvea, Alfredo de; Zanotti, Josinaldo; Luckmann, Daiane; Pizzatto, Mariana; Mazaro, Sérgio Miguel; Possenti, Jean Carlo.
O Brasil é o maior produtor mundial e o Paraná o maior produtor nacional de soja orgânica. A cultura vem sendo uma alternativa na viabilização econômica de pequenas propriedades, sobretudo no Sudoeste Paranaense. Com a expansão da atividade aumenta a demanda por pesquisas visando obter alternativas aos agrotóxicos no manejo fitossanitário da cultura. Assim, no presente trabalho, o objetivo foi avaliar o efeito da aplicação de extratos vegetais sobre a produção de fitoalexinas, o desenvolvimento de doenças e a produtividade de soja. O trabalho foi realizado in vitro e in vivo na UTFPR Campus Dois Vizinhos. Avaliou-se o alho (Allium sativum - 10 mL.L-1), neem (Azadirachta indica - 5 mL.L-1) e timbó (Derris spp. - 6 mL.L-1), isoladamente ou em combinações. Os...

Germination of guatambu seeds subjected to two light regimes
Provedor de dados: PFB - Pesquisa Florestal Brasileira
Autores: Guollo, Karina; Possenti, Jean Carlo; Felippi, Marciele.
Guatambu (Aspidosperma parvifolium A. DC.) is a species that faces extinction in different regions of Brazil. The aim of this study was to evaluate the influence of photoperiod on germination of guatambu seeds at 25°C. The statistical procedure used was factorial design with two factors. Factor A was seed lots (Mother tree A, B, and C) and factor B was photoperiod (dark and 12 h of photoperiod). Guatambu seeds are not affected by photoperiod condition during the germination process.

Chitosan in the induction of resistance to the damping off  tomato seedlings caused by Rhizoctonia solani Kuhn
Provedor de dados: Revista Scientia Agraria Paranaensis
Autores: Rocha, Rita de Cassia Dosciatti Serrão; Mazaro, Sérgio Miguel; Possenti, Jean Carlo; Freddo, Álvaro Rodrigo; Zorzzi, Ivan Carlos; Dallacosta, Nean Locatelli.
The objective of this study was to evaluate the potential of chitosan in the damping off tomato resistance induction caused by Rhizoctonia solani. The tomato seeds were submerged in solution with chitosan for twenty minutes in concentrations of 0.25; 0.5; 1 and 2% and in the control (distilled water only). The seeds were sown in polystyrene trays containing substrate inoculated with R. solani and kept in a growth chamber with 12 hours photoperiod and temperature of 25 ºC ± 2 °C for 14 days. After this period we evaluated the survival of seedlings, length and fresh weight and activity of the enzyme phenylalanine ammonia lyase (PAL), chitinase and β-1,3-glucanase. The results showed that chitosan when applied to the treatment of tomato seeds at a...

ELECTRICAL CONDUCTIVITY TEST APPLIED TO SEEDS OF FOREST SPECIES
Provedor de dados: Revista Scientia Agraria Paranaensis
Autores: Guollo, Karina; Possenti, Jean Carlo; Del Quiqui, Erci Marcos; Felippi, Marciele; Debastiani, Aline Bernarda.
The evaluation of electrical conductivity is one of the fastest tests to evaluate quality and vigour of the seed, however, studies with forest species are scarce. Thus, the aim was to verify the possibility to evaluate the physiological quality of forest seed species by the individual and massal electrical conductivity test in different imbibition periods. The experimental material consisted of seeds of the Gallesia integrifolia, Handroanthus chrysotrichus, Lonchocarpus campestris and Pterogyne nitens. For the individual method, 80 repetitions of one seed were used, which were placed in individual containers containing 50 ml of distilled water. The following imbibition periods were evaluated: 2, 4, 6, 8, 24 and 48 hours. The tests were placed in a...
