Abstract
Butia odorata (Barb. Rodr.) Noblick is an important regional genetic resource, however its commercial propagation is difficult by the shortage of plant breeding information and seedling formation. The objective of the study was to characterize the physiological behavior of B. odorata seeds by desiccation and conservation at different temperatures followed by viability analyses for further physiological classification. Mature fruits of B. odorata were collected and depulped. For desiccation, the diaspores were dried whole in an oven with a constant temperature 30 oC for 24 hours. The storage was carried out in negative temperature with the diaspores packed in a polyethylene bag. At the end of each period, a new water content determination and the viability test were performed. It can be inferred that B. odorata seeds have orthodox behavior because they presented the viability index above 90% with a water content of 6.14% and storage at sub-zero temperature. In addition, viability was maintained around 70% after storage with negative temperature and 5% humidity for 32 months.
期刊介绍:
The Iheringia, Série Botânica is a publication edited by the Museu de Ciências Naturais, Fundação Zoobotânica do Rio Grande do Sul, since 1958. The name Iheringia is actually a tribute to Hermann von Ihering (a German researcher who became a Brazilian citizen) and his important studies in the Natural Sciences.The journal has the mission of publishing articles, reviews and original scientific notes that cover diverse areas in Botany, and may be written in Portuguese, Spanish and English.
The journal is widely available in both international and national scientific community. The issues are published and distributed twice a year to 118 national institutions and 152 international institutions. The distribution is either free of charge or by exchange.
