DANNER, Moeses Andrigo et al. Seedling development of jabuticaba fruit trees (Plinia sp.) in different substrates and sizes of containers. Rev. Bras. Frutic. [online]. 2007, vol.29, n.1, pp. 179-182. ISSN 0100-2945.  http://dx.doi.org/10.1590/S0100-29452007000100038.

The experiment was carried out at UTFPR, Campus Pato Branco, from april 2005 to april 2006 with the aim of testing different substrates (Plantmax^® Hortaliças; soil of the native wood + vermicompost (1:1 v/v); soil of the native wood + medium sand + vermicompost (1:1:1 v/v); soil of the native wood + vermiculite + vermicompost (1:1:1 v/v); and vermicompost) and different volume of containers (577 cm³ e 1963,5 cm³) on the seed emergence and formation of 'jabuticaba' fruit tree seedlings. The percentage of emergence was evaluated and it was realized the calculation of EVI (Emergence Velocity Index) ninety days after seed germination. Twelve months after seed germination it was evaluated the seedling height, diameter of stem and foliar area, dry matter of the roots and the canopy. The results showed that the substrate Plantmax^® Hortaliças in the two recipients and the substrate ½ soil of the native wood + ½ vermicompost in the biggest recipient (1963,5 cm³) presented the best development of the 'jabuticaba' fruit tree seedlings.
