| 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... |
