“…Similar to D. decaryi, other palm species, such as Carpentaria acuminata (carpentaria palm) and Ptychosperma elegans (solitaire palm), have shown tolerance to salinity during the seed germination process (Batista et al, 2016). Moreover, species from other plant families, including Festuca arundinacea (tall fescue) and Phleum pratense (Timothy grass), have exhibited similar patterns (Sharavdorj et al, 2021). Understanding salinity tolerance is crucial for developing production strategies in regions affected by salt stress, as over 20% of irrigated land and 8.7% of global soils are estimated to be impacted by salt stress as reported by the Food and Agriculture Organization [FAO] (2021).…”

A palmeira triângulo (Dypsis decaryi), nativa de Madagascar e ameaçada de extinção em seu habitat, apresenta diversas características de interesse ornamental, tornando-a uma espécie importante para o mercado internacional. O principal método de propagação desta planta é por semente, que é influenciado por vários fatores como época de semeadura e salinidade. A variação de fatores ambientais em diferentes épocas de semeadura pode influenciar o processo de germinação enquanto que o estresse salino pode causar diminuição na germinação e até morte de sementes, afetando a produção de mudas. Desta forma, o objetivo deste trabalho foi avaliar o comportamento germinativo de sementes de Dypsis decaryi em diferentes concentrações salinas de cloreto de sódio (NaCl) e cloreto de potássio (KCl) em duas épocas. O delineamento experimental utilizado foi o inteiramente casualizado; o experimento foi realizado em esquema fatorial 2 x 2 x 5, sendo duas épocas de condução do experimento (verão e inverno), dois tipos de sais (NaCl e KCl) e quatro concentrações salinas (25, 50, 75 e 100 mM) e ausência de sais - controle; foram quatro repetições e 25 sementes por parcela. Foram avaliadas porcentagem de germinação, índice de velocidade de germinação e tempo médio de germinação. A espécie se mostrou tolerante à salinidade simulada por KCl e NaCl, durante o processo de germinação de sementes, o qual foi influenciado pela época de semeadura, concentrações salinas e interação entre épocas e concentrações. Não houve efeito significativo de forma isolada entre os tipos de sais, para interação de épocas e sais e, entre os três fatores avaliados.

“…Based on the relationship between total germination and duration of combined exposure to salinity, it is observed that the total germination might be 20% greater recovering in distilled water than in 50 or 100 mM NaCl solutions (Figure 6). Thus, the previous studies may have overestimated the recovery germination percentage and rates of halophytes and glycophytes under salt alleviated field conditions, as the recovery germination was only tested in distilled water [10,[41][42][43][44][45].…”

Germination events of plants often occur after rainfall in saline environments where the soil salinity is diluted, viz recovery germination. Previous germination studies have rarely considered the duration of exposure to salt stress, and none of them have investigated recovery germination under low-salt concentration, other than in distilled water. The main objective of this study was to investigate the effects of salinity, exposure duration and low-salt recovery solutions on seed germination of the weed Chenopodium acuminatum to get a clear insight about the germination strategy exhibited by this species in a saline habitat. Seeds were initially exposed to 0–400 mM NaCl for 10, 20 and 30 d. The subsequent recovery experiment was conducted differently. For those initially treated with 100 and 200 mM NaCl, the recovery solution was distilled water, while for those initially treated with 300 and 400 mM NaCl, the recovery solution was distilled water, at 50 and 100 mM NaCl. Results showed that the recovery germination percentage and rate significantly decreased when the exposure duration extended. Seeds could subsequently recover to germinate at high percentages at recovery salt solution concentrations for a short duration, but the recovery percentages and rates in high salinity, combined with high exposure duration and relatively high recovery salt concentrations, were remarkably lower. More than 30% of the ungerminated seeds were viable after the recovery experiment. We suggest that Ch. acuminatum exhibits a ‘cautious’ strategy of germination to avoid injury from long-term salt stress and ensure survival for the subsequent continuation of its population under unfavorable saline conditions.

“…It can affect seed germination and site through osmotic stress, the ion-specific effect, and oxidative stress. Salinity retards or prevents seed germination through various factors [51,52]. All kinds of techniques can improve the seedling emergence rate and stand establishment rate under salt conditions [53][54][55].…”

Seed priming (SP) treatments are widely used in agriculture and restoration to improve seed germination and seedling vigor. Although there exists a considerable amount of scientific literature on SP, it has seldom undergone visual and quantitative analyses. To gain insights into the patterns observed in SP research over the last three decades, we conducted a bibliometric analysis using the Science Citation Index-Expanded (SCI-E) database, aiming to minimize the similarity score in plagiarism detection. This analysis offers a thorough examination of yearly publications, temporal patterns in keyword usage, the top-performing journals, authors, institutions, and countries within the field of SP. Our research findings suggest a steady annual increase of 10.59% in the volume of SP publications, accompanied by a significant upward trajectory in the average citations received per paper annually. According to the analysis of keywords, it was found that “priming” and “germination” emerged as the most frequently used terms in the field of SP research. Seed Science and Technology ranked first among the top journals, and Plant Physiology had greater influence in the field of SP in terms of number of citations. The majority of the top 10 productive institutions were situated in developing countries. In addition, these nations exhibited the highest volume of published works and citations. Our analysis revealed a shift in research focus within the field of SP over the past three decades, transitioning from agricultural science to encompass plant science and environmental science. With the growing recognition of SP’s research across different disciplines, there exist abundant prospects for international and interdisciplinary partnerships, collaborative organizations, and progress in this field.
