“…The SSR08 locus had the highest He (0.96), I (2.85), and polymorphism information content (PIC = 0.94) values, which revealed more abundant genetic information than the other loci. There were fewer alleles detected at SSR03 (7) and SSR14 (8) than at the other loci (9~19), and the level of genetic diversity at these two loci was lower than that at the other loci. There was a high proportion of T. sebifera homozygotes at 16 SSR loci.…”

“…The colors of T. sebifera leaves in autumn are relatively diverse, such as purple, red, orange, and yellow. In recent years, ornamental T. sebifera breeding has been carried out, and some ornamental colored cultivars have been developed [6,7]. There are 21 licensed T. sebifera cultivars in China with different autumn colors and different leaf traits, and these cultivars are also valuable materials for breeding.…”

Triadica sebifera is an important landscaping tree species because of its colorful autumn leaves. In recent years, some cultivars have been bred and licensed, but it can be difficult to identify them from their morphological traits due to their similar phenotypes. To explore the genetic relationships and construct a fingerprint of the cultivars, the licensed T. sebifera cultivars were analyzed using SSR markers. A total of 179 alleles were identified among the 21 cultivars at 16 SSR loci, and these alleles exhibited a high level of genetic diversity (He = 0.86). The genetic variations mainly occurred among cultivars based on an analysis of molecular variance (AMOVA). According to phylogenetic analysis, principal coordinate analysis (PCoA), and Bayesian clustering analysis, the genetic relationships were independent of geographic distances, which may be mainly due to transplantations between regions. Some cultivars with different leaf colors showed obvious genetic differentiation and may be preliminary candidates for cross-breeding. Finally, the fingerprint for the licensed cultivars was constructed with two SSR markers. The results of this study can provide technical support for the application and legal protection of licensed Triadica sebifera cultivars.

“…The plant Symplocos paniculata is widely recognized for its extensive traditional usage across various regions in Asia, notably China, India, and South Asia [ 1 , 2 , 3 , 4 ]. The role of this species in various ecosystems is crucial, as it serves as a vital source of sustenance and habitat for both humans and wild life [ 5 , 6 , 7 ]. Significantly, the fruit of S. paniculata exhibits a high oil content (~35% crude fat in dried fruit), predominantly composed of unsaturated fatty acids, rendering it suitable for utilization as an edible vegetable oil in certain mountainous regions of China [ 8 , 9 , 10 ].…”

Symplocos paniculata are reported to exhibit seed dormancy, which impedes its cultivation and widespread adoption. In this study, a comprehensive method was established to overcome seed dormancy by subjecting seeds to scarification in 98% H2SO4 for 10 min, followed by 1000 mg·L−1 GA3 soaking for 48 h and stratification at 4 °C for 100 days. The seed germination percentage has increased significantly, to a peak of 42.67%, though the seeds could not germinate timely by NaOH scarification. Additionally, the dynamic changes of key stored substances (proteins, soluble sugars, starches, and fats), associated enzyme activities (amylases, peroxidase, and catalase), and endogenous hormones (abscisic acid, gibberellic acid, and indole-3-acetic acid) in seeds were investigated. The results demonstrated a continuous degradation of starch and fat in S. paniculata seeds, while the levels of protein and soluble sugar exhibited fluctuations, which probably facilitated seed dormancy breaking through energy supply and transformation. The enzymatic activities underwent rapid changes, accompanied by a gradual decrease in ABA content within the seeds with increasing stratification time. Notably, GA3, GA3/ABA, and (GA3 + IAA)/ABA showed significant increases, indicating their positive regulatory roles in seed germination. This study clarified the dormancy mechanism and established an effective method for the release dormancy of S. paniculata seeds.

“…Por ello muchas especies del género tienen potencial para aprovechamiento en química y medicina (Badoni, et al, 2010;Patel, et al, 2012;Farooq, et al, 2017;Kar & Kumar, 2017). En China se ha reportado el uso de Symplocos paniculata como planta ornamental para paisajes urbanos, así como la utilización del aceite de los frutos para la producción de biodiesel (Liu, et al, 2017).…”

El género Symplocos registra ocho especies en Colombia, entre ellas Symplocos theiformis, llamada “té de Bogotá” debido a sus cualidades astringentes y tónicas similares a las del té y el café. Tiene un alto potencial de aprovechamiento y presenta una distribución restringida en las zonas rurales del Distrito Capital, por lo que su propagación y conservación son importantes. El objetivo del presente estudio fue evaluar la tolerancia a la desecación en las semillas, así como su dormancia fisiológica mediante la medición, bajo condiciones controladas de invernadero, del porcentaje de germinación y el tiempo medio de germinación utilizando semillas escarificadas y ácido giberélico (AG3: 400 ppm) y frescas, con un contenido de humedad de 10 y 5 %. Todos los tratamientos iniciaron la germinación en un término de 97 días; el porcentaje de germinación de las semillas frescas con un contenido de humedad de 10 y 5 % y de aquellas tratadas con AG3 fue de 41,7, 26,7, 28,3 y 18,3 %, y el tiempo medio de germinación en días fue de 213,8, 210,6, 194,1 y 211,5, respectivamente. La tasa diaria de crecimiento promedio fue de 0,12 mm/día y las plántulas alcanzaron 4,2 cm de alto a los 183 días, y el 92,1 % sobrevivió hasta los 363 días. No hubo diferencias estadísticas significativas entre los tratamientos en cuanto al porcentaje de germinación (p=0,2309) ni en el tiempo medio de germinación (p=0,4517). Se pudo concluir que, aunque no hubo diferencia entre los tratamientos, dada la disminución del potencial germinativo, las semillas se pueden considerar recalcitrantes al almacenamiento, además, la germinación es lenta y asincrónica en el tiempo, la propagación sexual es viable y su conservación ex situ a largo plazo es factible en colecciones vivas, bancos de plántulas o bancos de germoplasma in vitro.
