Conservação de sementes de cedrorana (Cedrelinga catenaeformis Ducke) - LEGUMINOSAE.

Abstract

Results are presented on conservation Cedrorana (Cedrelinga catenaeformis Ducke) seeds, stored with 12,1% moisture content and 80% of germination under environmental laboratory conditions (24,7°C of min. temp. - 27,9UC of max. and 73,5 of relative humidity) and into refrigerator 6,4-8,1°C and 50% of relative humidity) in two packages. Independent of experimental conditions, since 30 days of storage was ocurred a considerable reduction in germination percentage of the seeds stored in polyethylene bags and paper kraft bags. At the temperature of 6,4 - 8,1°C during 90 days of storage the better results were obtained when the seeds were conservated in polyethylene bags and paper kraft bags. In environmental conditions paper kraft bags were prejudicial for the conservation of this species.
