Resumo: |
This work aimed to evaluate the conservation of the seeds of the craibeira (Tabebuia aurea (Silva Manso) Benth. & Hook. F. ex. S. Moore) in differents storage environment and packings. The craibeira seeds were collected from 20 trees located in the metropolitan area of city of Recife-PE. After the collection, seeds were submitted to selection and homogenization. The seeds of water 14,94% were conditioned in the packings Kraft paper bag, poliethylene bag and metal recipient in stored under environmental laboratory (25,68 °C and 63,83%), refrigerator (5,08 °C and 48,70%) and dry cold (20,48 and 41,73%) during nine month period. The experiment was completely ramdom, with 4 repetitions of 25 seeds. The physiologic quality of the seeds was evaluated at the beginning and at every 30 days of storage, through the germination and vigor (index of germination speed (IVG) and root length) determinate seed moisture content. The results showed that the seeds present the largest germination averages and vigor when conditioned in Kraft paper bag or metal recipient, in the dry cold |
