“…Este valor de germinación fue inferior a lo encontrado por Fontana et al (2016) quienes determinaron que con las mismas pruebas de EA con soluciones salinas el porcentaje de germinación de semillas de Prosopis alba Griseb. fue del 80%, lo anterior, indica que el vigor es afectado por la procedencia de las semillas, el tratamiento aplicado, también por características heredables resultado de la interacción de las especies con el ambiente (Montaño et al 2020).…”

Se evaluó la germinación y el vigor de las semillas de mezquite (Prosopis laevigata) en función de las condiciones de almacenamiento. Se utilizaron semillas almacenadas durante 10 años, mantenidas en frascos de vidrio a temperatura ambiente. A través de pruebas de envejecimiento acelerado se determinó el vigor, mediante soluciones saturadas de sal, cloruro de potasio (KCl), cloruro de litio (LiCl) y bromuro de potasio (KBr); y tiempos de almacenamiento (6, 12 y 24 h). Los resultados indican que las semillas tratadas con LiCl tienen valores superiores en porcentaje de geminación (60%) e índice de velocidad de germinación (0.83) comparado con las otras sales y el testigo. No obstante, tener en cuenta los factores que intervienen en la germinación de la semilla, ya que el vigor es afectado por las condiciones de almacenamiento y el vigor cambia conforme transcurre el tiempo.

“…Although C. swynnertonii and S. glaucescens did not show differences in seed germination and seedling emergence, the two species showed significant differences (p = 0.014) in seedling shoot height. This can be linked to their inherent differences in their capacity to mobilize growth factors like water, light, and mineral nutrients (Montaño-Arias et al, 2021). Like other plants within the genus Commiphora, C. swynnertonii is characterized by small trees or shrubs with short, thorny branches while S. glaucescens is a shrub or small tree with fleshy stems and branches with leaves spirally arranged, crowded near the ends of branches (Mihale et al, 2018).…”

Medicinal and pesticidal plant propagation is hampered by poor seed germination due to seed dormancy. This study aimed to enhance seed germination and seedling growth using various presowing treatments. A triplicated two-factor experiment in a Randomized Complete Block design was used. Soaking in water at 25°C for 24 h (T1), soaking in 60°C hot water for 10 min (T2), 10 ppm Potassium nitrate (KNO 3 ) treatment for 24 h (T3), 20 ppm Potassium nitrate (KNO 3 ) treatment for 24 h (T4), Treating seeds with Gibberellin (GA 3 ) solution at 250 ppm (T5), GA 3 Treating seeds with Gibberellin (GA 3 ) solution at 500 ppm for 72 (T6), Treating seeds with Gibberellin (GA 3 ) solution at 1000 ppm for 72 h (T7), and seeds without any pre-treatment were sown and used as control (T o ) on seed germination and seedling growth of two MPP species. The ability of a pre-sowing treatment to break seed dormancy was significantly dependent (p = 0.002) on the plant species. The effects due to interaction between presowing seed treatment and plant species on seedling growth parameters (height, branches/shoot, leaves/shoot/, leaf area, fresh and dry weight) were significant (p < 0.05). These results provide the basis for the sustainable use of MPPs through propagation and conservation.

“…The germinated seeds were counted from the day the experimentation began. For the germination, different variables were monitored namely: latent period (LP), final percentage germination (FPG), mean germination time (MGT), and germination rate (GR) (Ferradous, 2018;Montaño-Arias et al, 2021;Mwendwa et al, 2020).…”

Aim of study:The objective of this study was to optimize the germination of A. spinosa seeds after different physical pretreatments by thermal shock to establish a simple, effective, and less expensive procedure.Area of study: The study was conducted in the laboratory on seeds from four regions of Morocco (Aoulouz, Essaouira, Sidi Bou Othmane, and Boulaouane).Material and methods: The seeds were dried and stored. Before the launching of the experimental protocol, they were dehulled and applied each their pre-treatment for the four provenances. The pretreatment used are the following. C: control without thermal shock, HC1: freezing, HC2: hot water, HC3: freezing + hot water.Main results: The results showed that the onset of germination of argan seeds subjected to pretreatment HC3 was reduced by 2 days on mean compared to seeds that were subjected to pretreatment (C). The application of the cold or hot pretreatment allowed us to reach up to 82% of the final percentage of germination. However, the combination of two pretreatments allowed us to reach up to 100% of the final germination percentage.Highlights: Freezing combined with hot water significantly improved the germination of A. spinosa seeds. This pretreatment could be recommended in the nursery for practitioners.
