“…The same behavior was observed with seeds of Jatropha curcas by Zonta et al (2011) the vigor of which was reduced at 43 ºC. However, the drying of Passiflora edulis at temperature of 30, 35 and 40 ºC did not affect the quality of the seeds (Carlesso et al, 2008).…”

-The aim of this work was to evaluate viability and DNA ploidy of seed of Melanoxylon brauna submitted or not to fast drying, along soaking. The seeds were dried followed by germination and quantification of DNA ploidy pattern. There was a gradual decrease in germination percentage with increases in temperature and drying time. The DNA ploidy of embryonic axes that were not submitted to artificial drying indicated the existence of nuclei 2C, 4C and 8C. However, 95% of the tested embrios had 2C DNA ploidy . The seeds that were subjected to rapid drying also exhibited the presence of nuclei 2C, 4C and 8C and showed no significant differences ( p > 0.05 ) compared to seeds that have not passed through drying. It is conclude that the seeds of Melanoxylon brauna submitted to different drying times and temperatures show a gradual decrease in the percentage of germination; embryonic axes subject or not to drying seeds have 2C, 4C and 8C nuclei and drying does not affect the cell cycle of cells in the embryo of the seed. Termos para indexação: ploidia, citometria de fluxo, secagem.

“…In this case, the low germination values of the seeds from those progenies are probably related to storage conditions. Second (CARLESSO et al, 2008) storage for three and six months did not affect the physiological quality of seeds. It is well-known that storage highly affects the physiologic quality of the seeds, so the storage environmental conditions in the present study (refrigerator at 5 ºC) probably provided higher number of progenies with high emergency rate (Figure 1).…”

Lipid peroxidation and seed emergency in progenies of the yellow passion fruit plant

et al. 2012

-The objective was to evaluate the percentage of emergency plantlets and lipid peroxidation in seeds of 29 half-sib progenies of yellow passion fruit (Passiflora edulis Sims.) after 24 months under storage. The experimental design was completely randomized, with four replications of 50 seeds each, from which the treatments were the progenies (1-29). The evaluation of the percent plantlet emergency was accomplished at 14 and 28 days after sowing. The lipid peroxidation of the seeds was expressed as malondialdehyde (MDA) content that was determined by the TBARS method. Approximately 21% of those half-sib progenies maintained the viability of their seeds for twenty-four months under storage. The results point out a remarkable genetic variability for vigor and emergency of the yellow passion fruit plantlets, with occurrence of individuals with high and other ones with low capacity to maintaining the physiologic quality of their seeds after storage. Index terms: Passiflora edulis, genotypes, seeds, vigor, stress oxidative. PEROXIDAÇÃO LIPÍDICA E EMERGÊNCIA EM SEMENTES DE PROGÊNIES DE MARACUJAZEIRO-AMARELORESUMO -O objetivo foi avaliar a porcentagem de emergência de plântlulas e a peroxidação lipídica de sementes de 29 progênies de meio-irmãos do maracujazeiro-amarelo (Passiflora edulis Sims.), após 24 meses sob armazenamento. O delineamento experimental foi o inteiramente casualizado, com quatro repetições de 50 sementes cada, a partir do qual os tratamentos foram as progênies (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28 e 29). A avaliação da porcentagem de emergência das plântulas foi realizada aos 14 e 28 dias após a semeadua. A peroxidação lipídica das sementes foi expressa como conteúdo de malondialdeído (MDA), que foi determinado pelo método de TBARS. Aproximadamente 21% das progênies de meios-irmãos mantiveram a viabilidade de suas sementes para 24 meses de armazenamento. Os resultados apontam para uma variabilidade genética quanto ao vigor e á emergência de plântulas de maracujazeiro-amarelo, com ocorrência de indivíduos com alta e outros com baixa capacidade de manter a qualidade fisiológica de suas sementes após o armazenamento.

“…Low-temperature environments favour and preserve seed viability, as verified in C. vernalis seeds (Vieira et al, 2008). Similarly, Catunda et al (2003) observed that the refrigerated environment (4 °C) preserved the viability of yellow passion fruit seeds for a period of 10 months of storage, and when packed in glass and polyethylene containers, the physiological quality was preserved for 90 and 180 days, respectively (Carlesso et al, 2008). Sunflower seeds tolerated storage for 180 days, at temperatures below zero and presented viability and preservation of vigour, with low seed deterioration, indicated by the low level of peroxides (Motta et al, 2014).…”

The physiological quality of yellow passion fruit (Passiflora edulis Sims. f. flavicarpa Deg.) seeds with different water content placed in a cold chamber room and environmental conditions

Seed quality is extremely important for the crop production system, and storage conditions are important to preserve this quality. The objective this study was to evaluate the physiological quality of yellow passion fruit seeds with different water contents placed in a cold chamber room (4°C) and in a natural laboratory environment (25 ± 2°C) for a period of eight months (240 days). Passion fruit seeds were harvested in orchards of the southern region of Espírito Santo, with water content adjusted to 10%; 14%; 18% and 22%, and placed in a cold chamber room and a natural laboratory environment. Germination, germination speed index, shoot and root length, fresh and dry mass of normal seedlings were evaluated. The experimental design was completely randomized, with two environments (cold chamber room and natural laboratory environment) and with a plot experimental arrangement subdivided according to time, with four replicates of 25 seeds within each environment. Yellow passion fruit seeds placed in a cold chamber room and natural environment with 14% of water content presented a higher physiological quality during eight months of storage. Yellow passion fruit seeds placed in a cold chamber room and natural environment presented maximum germination and vigour with 60 days of storage. Yellow passion fruit seeds exhibit orthodox behaviour, and should be stored at 14% of water content, in a cold chamber room and natural environment, without loss of viability and physiological quality over eight months, presenting maximum germination and vigour after 60 days storage, without the presence of pathogens.
