“…A menor divisão celular, redução na formação de novas células, e menor taxa de alongamento celular promovem a formação mais lenta de folhas, as quais são menores e mais espessas. O crescimento das plantas é inibido em decorrência do prejuízo ao desenvolvimento da gema apical, atrofia dos ramos, diminuição da área folhar, amarelecimento e necrose das folhas (EPSTEIN;BLOOM, 2006;GARCIA et al, 2008;KANAI et al, 2014;COSTA, 2015).…”

A necessidade de repovoar áreas de mangue degradadas pela produção de sal marinho levantou a questão da viabilidade da produção de mudas de mangue branco (Laguncularia racemosa (L.) C. Gaertn) com água e substrato obtidos próximos aos manguezais. Para tanto, foram testados o substrato Areia de Restinga e suas misturas com proporções de 25 e 50% de fibra de coco, bem como irrigação com água doce ou água contendo 5% e 10% de água de rejeito de salina com alta concentração de sal (água-mãe). O delineamento experimental foi o inteiramente casualizado em esquema fatorial, os dados foram analisados por meio da análise de variância e as médias foram comparadas pelo teste de Tukey. As avaliações foram realizadas em cinco períodos de desenvolvimento de plântulas e incluíram massa seca total, altura de planta, diâmetro de caule, massa seca da parte aérea, massa seca da raiz e índice de qualidade de Dickson. O substrato de areia de restinga e a irrigação com água doce proporcionaram as melhores dimensões e qualidade das mudas de mangue branco, mas mudas de tamanho e qualidade muito próximos foram produzidas quando a água aplicada continha 5% da água salgada. Os resultados obtidos serão aplicados para a produção de mudas de mangue branco, economizando água de boa qualidade e reduzindo custos com substrato comercial. Palavras-chave: Degradação Ambiental.

Abstract The need to repopulate mangrove areas degraded by sea salt production has raised the question of the viability of producing white mangrove (Laguncularia racemosa (L.) C. Gaertn) seedlings with water and substrate obtained near the mangroves. Therefore, the substrate Restinga Sand and its mixtures with proportions of 25 and 50% of coconut fiber were tested, as well as irrigation with freshwater or water containing 5% and 10% saltworks brine with high salt concentration (bittern). The experimental design was completely randomized in a factorial scheme. Data analysis consisted of variance analysis and Tukey Test for comparison of means. Evaluations carried out in five periods of seedling development included total dry mass, plant height, stem diameter, shoot dry mass, root dry mass, and Dickson quality index. Restinga Sand substrate and irrigation with freshwater provided the best dimensions and quality of white mangrove seedlings, but seedlings of very close size and quality were produced when the applied water contained 5% of the saltworks bittern. The obtained results will be applied to produce white mangrove seedlings saving good quality water and reducing costs with commercial substrate. Keywords: Environmental Degradation. Forest Nursery.

“…A higher IVI value reflects a significant contribution of a species in the community and its habitat preference (Kiruba-Sankar et al 2018;Rani et al 2018). A. marina is adaptive to all the intertidal zones and tolerates low-to high-salinity conditions (Jayatissa 2006;Tamin et al 2011;Basyuni et al 2019;Cheng et al 2020), whereas R. stylosa can grow well under medium salinity, but its growth capability declines under high salinity (Kanai et al 2014;Basyuni et al 2019).…”

Abstract. Marpaung BA, Budiadi, Pertiwiningrum A, Lestari LD, Nurjanto HH, Widiyatno. 2022. Interspecific associations of mangrove species and their preferences for edaphic factors and water quality. Biodiversitas 23: 4626-4635. Scientists from different regions have reported failures of mangrove restorations that were predicted due to the unsuitability of the species for the habitats. Habitat preferences should become an important consideration for mangrove restoration and management. This study aimed to find interspecific associations between species and examine the edaphic factors and water quality suitable for mangroves. Eight research stations (and 24 sample plots) were established purposively based on the vegetation structure and salinity levels in successful mangrove restorations in East Lampung in 2020. In each plot, vegetal data and sediment and water samples were taken. The species domination was analyzed using the important value index (IVI), and interspecific associations were determined using a 2x2 contingency table. The edaphic factors and water quality were analyzed using principal component analysis (PCA) to find factors that had significant correlations among others. The effects of the edaphic factors and water quality on species regeneration were analyzed using multiple linear regression by backward elimination to develop a model of habitat preferences for mangroves. Based on the results, Avicennia marina and Rhizophora sp. were the dominant species in all the zones. Still, the lack of interspecific association ( ) showed that both species had different preferences for the habitat. We found four principal components (PCs) of edaphic factors—i.e., the environmental (soil and surface) temperature, dusty clay and Ca, inorganic nitrogen (NH4-N and NO3-N), and Mg—and two PCs of water quality, i.e., nontoxic pollutants (total suspended solids and turbidity) and anthropogenic factors (NO2-N and PO4-P), as predictors for multiple linear regression. The seedlings of A. marina had no specific preferences for edaphic factors but significantly preferred nontoxic pollutants (R2 = 0.619), while the seedlings of Rhizophora spp. significantly preferred a specific environmental temperature, dusty clay and Ca, and inorganic nitrogen (R2 = 0.768), and nontoxic pollutants (R2 = 0.755). Combining A. marina and Rhizophora spp. in mangrove restorations should be avoided. Therefore, spatial planting patterns or sequential planting based on the succession stages of the habitat could be established.

“…Biber (2006) stated that increasing salinity lead to the decrease of photosynthetic activities. Further effect of salinity stress was explained by Kanai et al (2014) which showed a decreasing growth rate of mangrove under salinity stress. High salinity decreased the leaf half-life of mangrove (Suárez & Medina, 2008).…”

Mangrove plants are sensitive to environment condition. This research aimed to analyze the linkages of mangrove growth and environment dynamics and to estimate the growth of mangrove along with the environment dynamics. The research was conducted through the field experiment by the plantation of A. marina in silvofishery pond canals. Data collection was conducted for 18 months with 3 months observation interval. The environment variables observed including temperature, salinity, turbidity, pH, dissolved oxygen, TSS, sediment organic matter, nitrogen and phosphorus, and the growth of mangrove seedling. Analysis was conducted through regression and modelling with Powersim software. The result showed that the height growth was affected by dissolved oxygen, temperature, salinity, turbidity and pH, while the diameter growth was affected by TSS concentration. Inversely, the growth of mangrove also had a significant effect on temperature, change of organic matter and nutrient sediment concentration. Simulation showed that the height and diameter growth rates of A. marina seedling were dynamically changed among periods. Simulated seedling growth for one year forecast resulted in the rate of 0.115024 to 0.282294 cm/day for height and 0.001287 to 0.006031 cm/day for diameter. The simulation also indicated the continuous accumulation of organic matter and nitrogen over time. This research concluded that under limited environment dynamic, the growth of mangrove could be estimated. This model is a novelty in ecological studies. This research might initiates the more advanced ecological studies. Systematic estimation of ecosystem behaviour could be applied to formulate the best management practices, particularly in the silvofishery activities.
