Tests for evaluating the physiological quality of pitaya seeds
Ortiz, Thiago Alberto; Moritz, Aline; Takahashi, Lúcia Sadayo Assari; Urbano, Mariana RagassiGermination test is used to assess the physiological quality of seeds; however, since it is carried out under ideal conditions, this test has not been shown sufficient for this purpose. Instead, it is possible to use vigor tests, although the lack of standardized methodologies has reduced their applicability and reproducibility. Thus, this study aimed to develop methodologies for conducting tests of germination...
Effects of the hydrogen potential and fungicide treatment on Pitaya seed germin...
Ortiz, Thiago Alberto; Moritz, Aline; Oliveira, Mariana Alves de; Takahashi, Lúcia Sadayo AssariThe objective of the present study was to evaluate pitaya seed germination under different hydrogen potentials, with or without fungicide treatment. A completely randomized design was employed under a 3 x 13 x 2 factorial scheme, corresponding to three pitaya species (white pitaya, pitaya hybrid I, pitaya hybrid II), thirteen hydrogen potentials (3.0, 3.5, 4.0, 4.5, 5.0, 5.5, 6.0, 6.5, 7.0, 7.5, 8.0, 8.5, and 9...
In vitro Establishment of Ocotea odorifera, O. catharinensis and O. porosa
Moritz, Aline; Degenhardt, Juliana; Dutra, Leonardo Ferreira; Hansel, Fabrício Augusto; Lima, Bruno Henrique de; Franceschi, Cristina do Rosário BatistaSeveral species of the Lauraceae family are endangered, due to the high value of their woods,and the consequent exploitation of natural populations. Among them, Ocotea porosa, O. odorifera and O.catharinensis, native from South Brazil, have recalcitrant seeds, what makes even more dificult their naturalregeneration. This work aimed to evaluate in vitro seed germination and multiplication of O. odorifera and O.c...
