“…Ghayyad et al (2010) obtained the best results in germination of P. mahaleb seeds by removing the endocarp and then applying GA 3 . Also, exogenous applications of GA 3 and H 2 O 2 prior to CS have been reported to improve germination in Prunus species seeds without endocarp (Imani et al, 2011;Zeinalabedini et al, 2009).…”

Sexual propagation of Prunus mahaleb is difficult due to seed dormancy. To overcome dormancy and maximize germination, various pretreatments have been applied, including stratification (warm and cold), gibberellic acid (GA 3 ), sulfuric acid scarification (AS), and endocarp removal. The results show that warm stratification (WS) prior to cold stratification (CS) does not improve seed germination and a long period of WS (3 months) is disastrous for germination. CS alone (up to 4 months) has been found to hasten and increase seed germination. Pretreatment of the seeds with exogenous GA 3 , during the CS period, has been observed to result in significantly higher seed germination. AS of seeds for 45 minutes prior to GA 3 (1000 ppm for 24 hours) plus CS (up to 1 month) pretreatment has been considered to reduce the mechanical resistance of endocarp and improve germination. However, extended time of AS (180 minutes) prior to GA 3 plus CS pretreatment has been found to harm the seeds. The removal of endocarp has been noted to significantly improve germination. Seeds without endocarp, which were pretreated with GA 3 (1000 or 2000 ppm for 24 hours) and then cold stratified for 1 month, have been noted to exhibit the highest germination percentages.

“…That is, the endocarp could be water-impermeable (Li et al, 1999), or it could be waterpermeable but exert strong mechanical resistance to expansion of the embryo (Nikolaeva, 1969). Also, the embryo may have some level of physiological dormancy (PD) and warm and/or cold stratification may be required for dormancy break to occur (Chien et al, 2002;Baskin et al, 2005;Persson et al, 2006;Chen et al, 2007;Imani et al, 2011). However, after PD is broken, it is still uncertain whether the embryo has enough growth potential to overcome the mechanical resistance of the water-permeable endocarp (Nikolaeva, 1969) as the covering structure may require some form of weakening.…”

Summer conditions break physiological dormancy of the embryo and promote opening of the endocarp, allowing seeds to germinate during winter conditions. By closely monitoring the environment that endocarps are exposed to in nature, dormancy breaking mechanisms can be identified and used to improve germination. These results outline for the first time how dormancy and germination are regulated in a species with a hard woody endocarp, insights which will significantly improve our understanding of other species with similar reproductive features.

“…Las semillas con germinación mayor a 60% se lograron con estratificación con endocarpio por 8 días a 5°C (T8), imbibición de semillas sin endocarpio por 48 h a 30°C (T6), imbibición de semillas sin endocarpio por 24 h a 30°C (T7), imbibición de semillas con endocarpio por 48 h a 5°C (T10) e imbibición de semillas con endocarpio por 48 h a 25°C (T5). En otras especies del género Prunus, la conservación del endocarpio limita la emergencia del embrión, mientras que, al quitarlo, se logran porcentajes de germinación altos (Chen et al 2007;Imani et al 2011). En este estudio, conservar el endocarpio no limitó la germinación de las semillas, lo cual puede representar menor tiempo dedicado a quitar el endocarpio, previo a la realización de los tratamientos.…”

“…Los resultados sugieren que las semillas de P. cer-cocarpifolia requieren acondicionamiento antes de ser propagadas en vivero. Esta característica es común en especies de Prunus y en diversas especies forestales de clima templado (Finch-Savage y Leubner-Metzger 2006; Imani et al 2011). La imbibición y la estratificación mostraron una gran capacidad para lograr la germinación de las semillas de la especie de estudio, pero la imbibición en agua durante 24 h a 25°C con endocarpio (T3) y estratificación por 8 d a 5°C con endocarpio (T8) destacaron por su eficiencia para aumentar la tasa de germinación.…”

“…Por ello, para preservar el equilibrio ecológico y el funcionamiento del matorral submontano de la Sierra Zapalinamé, es necesaria la recuperación de las poblaciones del durazno cimarrón, a través de la reforestación. Sin embargo, en especies de Prunus silvestres se registran bajos porcentajes de germinación en ausencia de tratamientos pregerminativos que permitan la emergencia del embrión (Imani et al 2011;Kim 2019). En el caso del durazno cimarrón, se desconoce si comparte esta característica y tampoco existe información sobre el efecto de tratamientos pregerminativos sobre las semillas de esta especie.…”

Prunus cercocarpifolia Villarreal (Rosaceae) is an endemic shrub species restricted to the Sierra Zapalinamé in southeastern Coahuila, Mexico. It is a refuge and food source for native fauna, but their populations have been affected by human activities. In this study, we evaluated 11 pregerminative treatments in seeds of this species. These treatments consisted of the imbibition in water and stratification at different times and temperatures. The treated seeds were sown, and we assessed the percentage of germinated, dark, and non-germinated seeds, as well as the pro- portion of normal and abnormal seedlings. The seed imbibition with endocarp for 48 h at 30°C reached the highest germination percentage (89%), with all seeds being germinated, and 58% of normal seedlings produced. With the stratification for 8 days at 5°C, all seeds were germinated and a 64% of normal seedlings was achieved. Implementing these treatments on nursery production can contribute to the conservation of this endemic species of northeastern Mexico
