EFEITO DE EMBALAGENS, AMBIENTES E PERÍODOS DE ARMAZENAMENTO NA GERMINAÇÃO E NO VIGOR DAS SEMENTES DE CEDRO (Cedrela odorata) EM MANAUS - AM

Packages, environment and storage periods effects i n germination and vigor of cedar (Cedrela odorata) seeds in Manaus, AM. Conservation of seeds of forest species is an impor tant practice for the best use of seedlings production. According to that, this research aimed to evaluate effects of different packaging, environments and periods of st orage of Cedrela odorata in conservation of viability and vigor of seeds. The seeds had been su bmitted to three periods of storage (3, 6 and 9 months) plus control, conditioned in plastic and pa per, in refrigerator and natural environment conditions. The adopted delineation was entirely ca sualized in factorial scheme, with 5 repetitions of 20 seeds. It was analyzed the following variables: percentage of germination and formation of normal plantule. Results indicated that seeds stored in na tural surrounding condition had presented drastic reduction in the germination and formation of norma l plantule throughout storage periods, on the other hand, in refrigerator condition reduction had been less intense. In relation to the kind of packaging it was not identify any effect, independe ntly of storage environment. It revealed that refrigerator conditions were efficient to preserve germination and vigor of cedar seeds.
