“…The highest germination percentage was recorded for scarified seeds cultivated in T6, which was composed of a mixture of commercial organic substrate, water, and gibbelleric acid. Thus, it is possible to affirm that the addition of gibberellin demonstrated positive effects, corroborating the results reported by other authors for passion fruit seeds (Grzybowski et al, 2019). The hormone gibberellin plays a role in the synthesis of RNAs and proteins responsible for seed germination, regulating the synthesis of α-and β-amylase enzymes responsible for the hydrolysis of seed reserve tissues, transforming reserves into amino acids, nucleic acids, and sugars, and displacing these compounds into regions of embryonic growth.…”

“…To achieve successful in vitro germination, abiotic stress must induce dormancy breaks using chemical and/or physical methods (Grzybowski et al, 2019;Jasper & Nyamweha, 2019;Saffari et al, 2021). The choice of appropriate culture media is also essential because different concentrations of salts can positively or negatively influence the germination process depending on the osmotic potential of seeds (Uçarlı, 2020), while the addition of enriching agents and growth regulators may be necessary for the success of germination (Miranda et al, 2018;Uçarlı, 2020).…”

The presence of salts in the culture medium and the addition of phytohormones, necessary to break seed dormancy in the in vitro germination of passion fruit, can induce critical values of osmotic potential. This can change the membrane permeability of seeds, affecting the hydration rate, enzyme release, ion transport, pH, and inhibitor values, which may decrease germination percentage. The aim of this study was to evaluate different types of culture media, composed of other substances, combined with mechanical techniques of tegument removal to determine the most appropriate culture medium for the in vitro germination of Passiflora edulis (Sims flavicarpa Deg.) seeds obtained by open pollination. The experimental design was completely randomized in a 10 × 3 factorial scheme (10 culture media × three types of seed-intact, scarified, and cut), with eight replicates and five seeds per plot. Scarified seeds cultivated in a medium composed of a commercial substrate and gibberellic acid presented a higher percentage of germination than intact or cut seeds cultivated in different concentrations of Murashige & Skoog (MS) medium. Scarification is a satisfactory method for breaking the dormancy of passion fruit seeds, and commercial substrates Bioflora® enriched with gibberellic acid may replace in vitro germination.

“…Exogenous dormancy is caused by tissues of the seed itself (extraembryonic), such as integument or parts of the fruit, and may be associated with physical, mechanical, and chemical factors. Physical dormancy, specifically, is caused by the impermeable nature of the integument of both seeds and fruit, which totally or partially restricts water diffusion to the embryo (Grzybowski et al, 2019).…”

Dormancy and evaluation of the physical-physiological quality in sweet potato [Ipomoea batatas (L.) Lam.] seeds by image analysis

et al. 2022

For the germination of sweet potato (Ipomoea batatas) seeds to occur, it is necessary to overcome dormancy, which makes it difficult to assess their physiological potential. The aim of this research was to define a methodology to overcome the dormancy of sweet potato seeds and use image analysis to determine their physical and physiological quality. Four genotypes of sweet potato seeds were used, namely UFVJM-5, UFVJM-22, UFVJM-38 and UFVJM-65. To overcome dormancy, chemical scarification with 98% H2SO4 for 10 and 20 minutes, hot water at 95 °C for 10 and 20 minutes, and mechanical scarification with electric grinder were tested. To evaluate the physical quality, the seeds were analyzed with X-rays and classified as intact, empty and malformed seeds. Using the GroundEye® system, the characteristics of color dominance, seed geometry and seedling length were quantified. Treatments with mechanical scarification with grinder and 98% sulfuric acid, for an immersion period of 20 minutes, are efficient to break dormancy in sweet potato seeds. There are genetic divergences between sweet potato genotypes, promoting the formation of different groups. The characteristics of color and geometry of the seeds are the ones that most contribute to genetic diversity of genotypes.

O presente estudo objetivou analisar a morfometria de frutos, sementes e plântulas de Guazuma ulmifolia Lam., além de testar diferentes modalidades de tratamentos para superar a dormência de suas sementes. Inicialmente foi realizada a biometria de frutos e sementes e, posteriormente, de plântulas. Os tratamentos utilizados para quebra da dormência foram: testemunha (T1); escarificação química com ácido sulfúrico (H2SO4) 98% por 5 min (T2), 15 min (T3), 30 min (T4) e 50 min (T5); escarificação química com ácido sulfônico (H-S(=O)2-OH) por 50 min (T6) e 60 min (T7); escarificação química com ácido muriático (HCl) por 60 min (T8) e; imersão em água quente (T9) a 90°C por 10 min. Depois de submetidas aos tratamentos, as sementes foram semeadas em folhas de papel germitest. Avaliou-se a porcentagem de germinação (%G), o índice de velocidade de germinação (IVE) e o tempo médio de germinação (TME). O delineamento experimental utilizado foi inteiramente ao acaso. Os dados foram submetidos à análise de variância e a comparação entre as médias realizadas através do teste de Tukey a 5% de significância. Somente o tratamento de imersão em água quente a 90º C por 10 min foi eficiente para superar a dormência em sementes de G. ulmifolia, proporcionando 68% de germinação. Os demais tratamentos não aumentaram significativamente a germinação, igualando-se à testemunha. Para a análise de variância do TME, não foram observadas diferença significativa entre os tratamentos realizados.
