However, immature seeds in in vitro cultivation can accelerate germination and produce normal axenic seedlings. The objective was to analyze the germination potential of embryos, seeds (immature and mature) in vitro and immature seeds ex vitro, and to select the explant of E. edulis with superior results for acclimatization. Three experiments were carried out: I: In vitro germination of zygotic embryos, immature seeds, intact and scarified mature seeds of E. edulis; II: In vitro germination of seeds and immature zygotic embryos of E. edulis in culture medium with GA3 and III: Acclimatization of seedlings from in vitro cultivation of immature seeds of E. edulis pre-germinated in different culture media and ex substrate vitro. We analyzed: germination, vigor and growth of seedlings in vitro and ex vitro, survival and growth of seedlings ex vitro. A completely randomized design was used, with three replications of 10 seeds in experiments I and II, and with six replications of five seeds in experiment III. The in vitro cultivation of immature seeds is advantageous in relation to zygotic embryos, mature seeds and ex vitro immature seeds. GA3, at concentrations of 0, 2, 4 and 8 mg L-1 for E. edulis seeds, did not induce seed germination. Immature seeds use nutritional reserves present in the endosperm for germination, because only through the solidification of water with agar is sufficient for the germination and initial growth of E. edulis, thus reducing production costs, discarding the need for a culture medium containing salts and nutrients.

- ItemPropagação de genótipos de Passiflora mucronata submetidos a estresses bióticos e abióticos(Universidade Federal do Espírito Santo, 2021-02-25) Oliveira, Patrick Alves de; Lopes, José Carlos; https://orcid.org/0000-0002-4880-0547; http://lattes.cnpq.br/1183524198654764; https://orcid.org/0000-0003-0077-4199; http://lattes.cnpq.br/0848131971739650; Alexandre, Rodrigo Sobreira; https://orcid.org/0000000252486773; http://lattes.cnpq.br/5340049196888351; Xavier, André da Silva; https://orcid.org/0000000292510301; http://lattes.cnpq.br/5661020509713522The species Passiflora mucronata Lam. has great ornamental, medicinal and genetic potential, can be used as a rootstock for commercial species, and is resistant to diseases such as bacteriosis and anthracnose. The success in the formation of seedlings depends on the knowledge about the propagation process of the plants. In sexual propagation, the stresses caused by water deficit and the presence of excess salts are highly harmful to seed germination; in asexual propagation, success depends on several factors, highlighting the standardization and quality of the cuttings used, due to the possibility of transmission of pathogens. Genotypes of P. mucronata Lam. have been suggested as resistant to soil pathogens, and may be an alternative rootstock for propagation of commercial passion fruit species. However, its stem has a smaller diameter than other species of Passifloraceae, which can hinder the grafting process. Therefore, there is a need for studies with the species. The objective was to study the seminiferous and vegetative propagation, resistance to biotic and abiotic stresses and the early rot etiology of cuttings of Passiflora mucronata Lam. Three experiments were carried out: Experiment I. Physiological quality of seeds of P. mucronata Lam genotypes. as a function of nitric oxide donor and salt stress. Four NO Tadalafil donors were studied: 0.0; 1.5; 2.5 and 5.0 mg L-1 in nine genotypes. The results showed that the G3 genotype treated with Tadalafil (1.5 mg L-1 ) had the highest germination (64%) and germination speed. The concentration of Tadalafil 5.0 mg L-1 ) reduced seed germination. Experiment II. Initial growth of clonal seedlings of Passiflora mucronata genotypes subjected to doses of Paclobutrazol (PBZ). Two genotypes (G5 and G7) and four PBZ procedures (0; 5; 10 and 15 mg plant-1 ) were studied, in which the application of PBZ promoted an increase in the diameter of plagiotropic shoots and the index of leaf area index, with increased photosynthesis and stomatal conductance. Experiment III. The etiology of P. mucronata precocious cuttings was studied. The isolation and morphological and genetic identification of the pathogen responsible for the high severity and death of P. mucronata cuttings in the cutting process was carried out. The analyzes confirmed the presence of F. incarnatum-equiseti in cuttings, making it the first report of the disease in P. mucronata in Brazil.

- ItemViabilidade de sementes de Passiflora edulis Sims. f. flavicarpa Deg(Universidade Federal do Espírito Santo, 2019-02-18) Lima, Paula Aparecida Muniz de; Lopes, Jose Carlos; https://orcid.org/0000-0002-4880-0547; http://lattes.cnpq.br/1183524198654764; https://orcid.org/0000000316011786; http://lattes.cnpq.br/3743426965294848; Ferreira, Adesio; https://orcid.org/0000000270001725; http://lattes.cnpq.br/5400370038397801; Alexandre, Rodrigo Sobreira; https://orcid.org/0000000252486773; http://lattes.cnpq.br/5340049196888351The quality of the seed is extremely important for the conduct of a crop and the storage conditions are fundamental in preserving its quality. In view of the above, the objective is to study the viability of seeds of Passiflora edulis Sims. f. flavicarpa Deg. with different water contents, the physiological quality of seeds of passion fruit hybrids cultivated at three altitudes and the behavior of these seeds stored in a cold room and natural environment. For the evaluation of the physiological quality of the seeds during storage, yellow passion fruit seeds with adjusted humidity levels were used: 10; 14; 18 and 22%, which were stored in plastic bags of 0.10 mm thickness and stored in a cold room at 4 °C and in a natural laboratory environment 25 ± 2 °C. In order to study the physiological quality of passion fruit hybrids stored in cold rooms and in the natural laboratory environment, hybrids were used: BRS Gigante Amarelo, BRS Sol do Cerrado and BRS Rubi do Cerrado, grown at three altitudes in the state of Espírito Santo (104 711 and 1016 meters). The variables studied were: seed water content, germination, germination speed index, shoot length, root length and dry mass of the seedlings. Yellow passion fruit seeds stored in a cold room and in a natural environment with 14% moisture present higher physiological quality during eight months (240 days) of storage. Seeds of yellow passion fruit stored in cold room and natural environment present maximum germination and vigor after 60 days of storage. The seeds of yellow passion fruit are orthodox and must be stored at 14% humidity, in a cold room and in a natural environment, without loss of viability and physiological quality for eight months (240 days), presenting maximum germination and vigor after 60 days without the presence of pathogens. Seeds of hybrids of Passiflora edulis Sims. f. flavicarpa Deg. can be stored in a natural environment or cold room. Seeds of hybrids of Passiflora edulis Sims. f. flavicarpa Deg. originating from altitudes of 104 and 711 meters present higher percentages of germination and vigor. Seeds of the hybrid Giant Yellow showed lower averages for the variables studied, regardless of the altitude of origin. Seeds of the hybrid Rubi do Cerrado from an altitude of 1016 meters have a higher percentage of germination and vigor and can be stored for 180 days in a natural environment or cold chamber without loss of viability. Seeds of the hybrid Sol do Cerrado, originating from the altitudes of 104 and 711 meters, present higher percentages of germination and vigor, and can be stored for 180 days in a natural environment or cold chamber without loss of viability.
