| In this study, we sought to identify efficient enzymes for use in monitoring the deterioration and loss of germination of Balfourodendron riedelianum (Engler) Engler seeds. The research was conducted at the Laboratório de Tecnologia de Sementes e Mudas of the Universidade Estadual do Oeste do Paraná, Campus Marechal Cândido Rondon, Paraná State, Brazil. Seeds were harvested at three collection sites and later submitted for processing, drying, initial characterization and storage in airtight packaging under controlled and uncontrolled storage conditions and uncontrolled. Tests were conducted at 0, 120, 240, and 360 days using a germination test, germination speed index, accelerated ageing test and the activity of peroxidase, phenylalanine ammonia-lyase... |

| The aim of this research was to identify fungi associated with “pau-cigarra” seeds (Senna multijuga). Evaluation was carried out in nine lots composed of seeds collected from mother trees at Atlantic Rain Forest located in Antonina, Morretes and Guaraqueçaba municipalities, Paraná state, Brazil. Sanitary analysis was carried out by adopting blotter test and agar plate test. Morphological characteristics were used for fungi identification. It was observed higher fungi frequency contaminating seeds over filter paper (blotter test) compared with agar plate test. Helminthosporium sp., Alternaria sp., Ulocladium sp., Pestalotia sp., Penicillium sp., Trichoderma sp., Chaetomium sp. and Monilia sp. were the most important genus found associated with S. multijuga... |

| This study aimed at to characterize morphologically the fruits, seeds and seedling development of Casearia decandra and examine the best substrate and temperature for seed germination. The fruits were collected from 13 mothers in the municipality of Irati, Parana State, Brazil. Tests were conducted to determine the weight of 1,000 seeds, number of seeds per kilogram and the seeds moisture content. To test the influence of different substrate and temperature on germination it was tested four temperatures: 20 ºC, 25 ºC, 30 ºC and 35 ºC on four substrates: sand, paper towels, roll paper and vermiculite. The fruit is spherical, with dry pericarp, thin, with glabrous , smooth, and light yellow surface. The seed presents ellipsoid shape, chartaceous, creamy and... |

| O objetivo deste estudo foi testar tratamentos de assepsia e sua influência na germinação e sanidade de sementes de quatro espécies florestais: Bauhinia forficata, Cedrela fissilis, Parapiptadenia rigida e Senegalia bonariensis. As sementes foram submetidas aos seguintes tratamentos: controle (T0); NaClO 1% por 3 min (T1); NaClO 2% por 1 min + 1 enxágue com água destilada (T2); álcool 70% por 1 min + triplo enxágue em água destilada + NaClO 0,5% por 1 min + triplo enxágue com água destilada (T3); Lysoform® por 1 min (T4); e álcool 70% por 1 min + NaClO 1% por 1 min + 1 enxágue com água destilada por 1 min (T5). Após, as sementes foram submetidas ao teste de germinação, sendo registrado comprimento, massa fresca e massa seca de plântulas, e teste de... |
