Although they are natives of São Paulo state, these fruits are discarded and cut down in their natural habitat, even in the legal reserve, which is causing their disappearance. Aiming to evaluate the pine bark substrate porosity in the development of Surinam cherry (Eugenia uniflora L.) and uvaia plant (Eugenia pyriformis Cambess), two experiments were conducted in greenhouses. The treatments were: 100% ground pine bark without separation of particles; 100% pine bark of ≤ 0,1mm; 75% pine bark of ≤ 0,1mm + 25% between 0,1-4,0 mm; 50% of pine bark ≤ 0,1mm + 50% between 0,1-4,0 mm; 25% pine bark of ≤ 0,1mm + 75% between 0,1-4,0 mm and 100% pine bark of 0,1-4,0 mm. The evaluations (stem diameter, length and average dry weight of seedlings) occurred at 90, 120 and 150 days after sowing. The results indicated that substrates with Total Porous Space (EPT) exceeding 90.0%, with over 75% of particles smaller than 0,1mm are not suitable for the production of Surinam cherry seedlings; and for uvaia plant it should be use substrates with EPT value less than 85%, since the small particles (≤ 0.1mm) should not exceed 25% of the total volume.Apesar de nativas do estado de São Paulo, estas frutíferas, são desprezadas e cortadas de seu habitat natural, mesmo na reserva legal, o que está provocando seu desaparecimento. Objetivando-se avaliar o efeito da porosidade em substratos de casca de pinus na produção de mudas de pitangueira (Eugenia uniflora L.) e uvaieira (Eugenia pyriformis Cambess) foram conduzidos dois experimentos em casa de vegetação. Os tratamentos foram assim definidos: 100% casca de pinus moído sem separação de partículas; 100% casca de pinus ≤ 0,1 mm; 75% casca de pinus ≤ 0,1 mm + 25% entre 0,1 - 4,0 mm; 50% casca de pinus ≤ 0,1 mm + 50% entre 0,1 - 4,0 mm; 25% casca de pinus ≤ 0,1 mm + 75% entre 0,1 - 4,0 mm e 100% casca de pinus 0,1-0,4 mm. As avaliações (diâmetro do caule, comprimento total e média de massa seca das plântulas) ocorreram aos 90, 120 e 150 dias após a semeadura. Os resultados indicaram que substratos com Espaço Poroso Total (EPT) superior a 90,0%, com mais de 75% de partículas menores de 0,1mm não são indicados para a produção de mudas de pitangueira; no caso da uvaieira, devem ser utilizados substratos com EPT inferior a 85%, desde que as partículas pequenas (≤ 0,1 mm) não ultrapassem 25% do total
