“…In the months of July and August of 2010 and 2012, higher temperatures were recorded compared with those in 2009 and 2011, which contributed to the fruit development and seed maturation. Variations in germination capacities depending on the growing season were also reported in the sweet cherry (Suszka 1976), apple (Lewandowski, Żurawicz 2009), and apricot (Szymajda et al 2013b). The results of our four-year study have shown that the seeds of the tested genotypes have significantly higher germination capacities compared with those of the control cvs Mandżurska and Siberian C. Among the tested genotypes, the seeds with the highest germination capacities were produced by the trees of BN-3, BN-4 and BN-8.…”

Szymajda M., Żurawicz E., 2014. Seed genotypes for harvesting seeds in the production of generative rootstocks for peach cultivars. Hort. Sci. (Prague), 41: 160-166.Six novel peach genotypes, designated BN-1, BN-3, BN-4, BN-7, BN-8 and BN-45, were assessed for usefulness as sources of seeds for production of generative rootstocks for peach cultivars. The genotypes BN-8 and BN-1 were the most intensely flowering, while the most abundantly and regularly fruiting genotype was BN-8, which also produced the smallest stones. The smallest fruits and the highest seed yields were produced by the genotypes BN-8 and BN-7. All of the genotypes under assessment produced seeds with higher germination capacities compared with the two control cultivars, Mandżurska and Siberian C, with the seeds of the genotypes BN-8, BN-4 and BN-3 exhibiting the most significantly elevated germination capacities. The most stones with two seeds were produced by the genotypes BN-45 and BN-3; however, produced a smaller fruit crop than did BN-8. Considering the characteristics assessed, the best as a seed source trees was genotype BN-8.

“…Apricot seeds require cold stratification to break dormancy. For this, it is necessary to keep the apricot seeds at 4-7 ºC degree for 90-105 days (Fadl et al 1978;Polat 2007;Szymajda et al 2013).…”

There is great interest in developing strategies to reduce the detrimental effects of salinity stress to improve plant growth and yield. The effects of plant-derived smoke on seed germination and plant growth, depending on concentration and time, are widely known. Although it has been suggested that plant-derived smoke and Karrikin (KAR1) tolerate the harmful effects of abiotic stress in plants, there is a lack of comprehensive information on biochemical and molecular changes related to KAR1 and smoke water (SW) in plants. Here we extensively compared the effects of SW and KAR1 on seed germination and morphology. Here we comprehensively compared the effects of SW and KAR1 on seed germination and morphological, biochemical, and molecular changes observable in the examined seeds. Moreover, we also showed that it regulated the expression of some genes encoding antioxidant enzymes in apricot seedlings (Prunus armeniaca L.) exposed to salinity stress (100 mM NaCl). Morphologically, we observed more adverse effects with decreased concentration in the SW treatment and increased concentration in the KAR1 treatment. The data revealed that SW (1:1000 v/v) and KAR1 (1µM) increased the expression levels of catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPX) genes in the samples taken from the apricot seedlings treated with salt at hours 3, 6 and 9. This increase varies in SW and KAR1 depending on time. When the biochemical results were examined, it was seen that the application of SW and KAR1 to the seedlings under salinity stress led to a significant decrease in the thiobarbituric acid reactive substances (TBARS) content. We can assert that SW is more effective than KAR1 on TBARS content. Morphological, molecular, and biochemical results revealed enhanced germination, growth, gene expression, and TBARS content in apricot seeds and seedlings exposed to SW and KAR1. This data may be applicable to more comprehensive trials.

“…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.
