“…However, this propagation technique exhibits difficulty due to seed dormancy. Many Prunus species, including the seeds of P. mahaleb, have two different types of dormancy: internal or embryo dormancy and external or endocarp dormancy (Ghayyad et al, 2010;Martinez-Gomez and Dicenta, 2001;Mehanna and Martin, 1985).…”

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.

“…a successful micro propagation protocol for P. emblica in order to expand its commercial market. According to the observations made P. emblica seeds seem to have seed coat imposed dormancy as in peach (Mehanna & Martin, 1985). Research conducted with Arabidopsis gibberellin deficient mutant strains indicated that, seed coat imposed dormancy can be overridden by application of gibberellin at the stage of germination (Foley, 2001).…”

Phyllanthus emblica L. is an important constituent of Ayurvedic medicine and a fresh fruit species in the market in Sri Lanka. Therefore, it has a high potential to be established as a commercial fruit crop. The seeds of P. emblica are semi orthodox and exhibit a long dormancy period hindering the natural sexual propagation. Therefore, it still remains as an underutilized fruit crop in Sri Lanka due to its lack of quality planting material and poor propagation techniques. Long term dormancy also causes a big challenge in germinating seeds to create populations in breeding programs. In order to promote P. emblica from its underutilized status, what seems most feasible is to develop a method to break up the seed dormancy artificially. In order to do so, the methods of breaking the dormancy of P. emblica seeds have to be studied. Therefore, the aim of this study was to identify a method to break up the seed dormancy of P. emblica. The seeds were extracted from 21 trees belonging to three different districts in Sri Lanka. The selected viable seeds were subjected to four different pre treatments: none treated seeds (i.e. control), seeds scarified, seeds scarified and treated with 1% gibberellin and seed coat removed and followed by seeds treated with 1% gibberellin. From the four treatments, seed dormancy was overturned with a germination percentage of 43% by the seed pre treatment where the seeds were scarified and treated with 1% gibberellin and no other pre treatment methods were successful in breaking the dormancy. This suggests that the natural germination potential of P. emblica seeds is very low and it can be overridden by seed scarification and gibberellin pre treatment.

“…The endocarp itself is also a source of germination inhibitors, the concentration of which decreases during stratification (Chen et al, 2007). As a consequence, the removal of the endocarp reduces the time required for stratification and increases the number of germinated seeds in many species of woody plants, including peach, sour cherry, sweet cherry and Mahaleb cherry (Zielinski, 1958;Suszka, 1964;Mehanna & Martin, 1985;Jakubowski, 2000;Martínez-Gómez & Dicenta, 2001;Jensen & Kristiansen, 2009;Ghayyad et al, 2010).…”

“…The inhibitors contained in the seed coat and the endosperm prevent the growth of the radicle in seeds of the genus Prunus. The removal of the seed coat together with the endosperm allows the seeds of peach (Mehanna & Martin, 1985;Martínez-Gómez & Dicenta, 2001), sweet cherry (Zielinski, 1958;Michalska, 1982) and sour cherry (Jensen & Kristiansen, 2009) to germinate within a dozen or so days without the need to subject them to stratification. However, the upper part of the embryonic axis of germinated seeds that have not been subjected to chilling shows developmental disorders.…”

“…It is a well-known fact that the deep dormancy of Prunus seeds is broken during their post-harvest maturation while being subjected to stratification (Suszka, 1967;Mehanna & Martin, 1985;Martínez-Gómez & Dicenta, 2001;Jensen & Kristiansen, 2009;Seliga & Żurawicz, 2011;Szymajda, et al, 2011;Szymajda, et al, 2013;Szymajda & Żurawicz, 2014), under the influence of low temperature, causing the decomposition of germination inhibitors (Chen et al, 2007). It is often the case, however, that even after long-lasting, stratification, not all of the stratified seeds germinate.…”

The deep dormancy of the Prunus species seeds is caused by the presence of germination inhibitors, mainly abscisic acid (ABA)-in the endocarp, the seed coat and endosperm, and in the embryo. As a consequence, the removal of the endocarp, the seed coat together with the endosperm increases the number of germinated seeds. The effect of different treatments of seeds of three peach cultivars-'Madison', 'Elberta' and 'Rakoniewicka', and of three apricot cultivars-M II-42, 'Bella' and 'Somo', were assessed in terms of seed germination and the growth of obtained young seedlings. Seed treatments involved different duration of stratification period at 5°C and removing endocarp, seed coat with endosperm and the part of cotyledons of the embryo. The best seed/embryo germination, about 96% for the peach cultivars and practically 100% for the apricot cultivars, was obtained by stratifying seeds for 90 days and then removing the seed coat together with the endosperm and subjecting the extracted embryos to a temperature of 20°C. The seedlings obtained from the seeds treated this way have shown good growth. Using these treatments, it was possible to obtain a larger number of apricot and peach seedlings, and thus increase the breeding efficiency of these species.
