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.
飞机草种子在低温下干燥和贮藏的耐受性。Rodr。)Noblick
臭椿(倒钩)Rodr)。Noblick是一种重要的区域遗传资源,但由于缺乏植物育种信息和幼苗形成,其商业化繁殖存在困难。本研究的目的是通过不同温度下的干燥和保存来表征臭臭草种子的生理行为,并对其进行活力分析,以进一步进行生理分类。收集了臭椿的成熟果实并进行了脱浆处理。干燥时,在恒温30℃的烘箱中干燥整个树脂24小时。储存在负温度下进行,并将分散剂包装在聚乙烯袋中。在每个周期结束时,进行新的含水量测定和活力试验。结果表明,果臭草种子活力指数在90%以上,含水量为6.14%,低温贮藏条件下,果臭草种子具有正统行为。在负温5%湿条件下贮藏32个月后,存活率保持在70%左右。

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.
