temperature influence on the germination of diaspores of ocotea odorifera vellozo) rohwer (canela-sassafrÁs)

Abstract

The experiment was developed at the Seed Laboratory of Forestry Sciences Department of Federal University of Paraná – UFPR, in order to determinate the effect of the temperature: 20, 25 and 30^o C, and the remotion of the outer coat (endocarp and tegument) on seeds germination the Ocotea odorifera (Vel.) Rohwer. The diaspores were collected at Fazenda Rio Grande, Paraná State, in a remaining Ombrophylous Mixed Forest. It was adopted the entirely randomized statistical model, The diaspores without outer coat presented a higher germination percentage and germination speed.
