Abstract

DANNER, Moeses Andrigo et al. Storage in vacuum enhance seed viability of jabuticaba tree. Rev. Bras. Frutic. [online]. 2011, vol.33, n.1, pp.246-252.  Epub Apr 20, 2011. ISSN 0100-2945.  https://doi.org/10.1590/S0100-29452011005000037.

The objective of this study was to evaluate the viability of seeds of jabuticaba tree (Plinia cauliflora) under different storage conditions. For this, two experiments were conducted. In the first was tested the viability of seeds stored under three different temperatures (room temperature, 12°C and 6°C) and storage periods (5, 10, 20, 40 and 80 days after seeds extraction). In the second experiment was tested the viability of seeds stored in polypropylene bags in vacuum with three conditions (with sterile water, with phosphate buffer pH 7.0 and in dry) and storage periods (5, 20, 35, 50 and 65 days after seeds extraction). Under normal atmosphere, the seeds of jabuticaba tree kept viability for only five days, with higher emergence at room temperature (83.35%). Seeds of jabuticaba tree totally lose viability with water content near 10%. Seeds of jabuticaba tree stored in vacuum with phosphate buffer kept a reasonable viability (41.6%) up to 65 days of storage.

Keywords : Plinia cauliflora; recalcitrant seed; seed water content; seed conservation.
