Luz, substrato e temperatura na germinação de sementes de cedro-vermelho

Abstract

This work aimed to evaluate the kind of substrate, and temperature and light conditions more suitable for seed germination of Cedrela odorata L. The experimental design adopted in all experiments was the completely randomized design with four repetitions of twenty-five seeds each. The constant temperatures (25 and 30°C), the alternated temperature (20-30°C), and the coconut fiber and sand substrates are the better conditions for seed germination of C. odorata. Seed germination of the studied specie showed no sensitiveness to the different levels of light applied.
