“…Among the assessed genotypes, the lowest number of damaged flower buds, on average for the three years of the study, was found in the seed genotypes BN-8 and BN-1 (31.6% and 36.8%, respectively). These results are consistent with the results of the previous study, in which the buds of these genotypes were found to have high tolerance to winter frosts (Szymajda, Żurawicz 2014). Among the assessed clones, the lowest number of damaged buds, on average for the three years of the study, was in the genotypes 6A-35DN (40.7%) and 6A-9DN (41.3%), whereas among the cultivars it was in Saturn (46.5%) and Harnaś (47.4%).…”

“…Therefore, the proper methods to analyze stone fruit seeds have been of great interest, especially when they aim at obtaining information expressing their physical and physiological quality (Wang et al, 2016;Thakur, 2015;Szymajda and Żurawicz, 2014;Moreira et al, 2012;Rahemi et al, 2011).…”

-This study aimed at determining and correlating the main morphometric characteristics of fruits and seeds with the germination potential and vigor of eight peach rootstocks. The experimental design was completely randomized, with four replications of 50 seeds per treatment. The analyzed variables were: length, width, thickness, fresh mass of fruit and seeds, moisture content of seeds, percentage of seeds attacked by fungi and intact seeds, germination percentage, germination speed index (GSI) and mean germination time (MGT). The Capdeboscq, Aldrighi and Tsukuba 1 cultivars showed higher values of length, width, thickness and fresh mass of seeds compared to other cultivars, presenting a relationship with the later period of fruit ripening. Regardless of the fruit ripening time, the germination percentage was high, ranging between 93% and 100% for all cultivars. In addition, the fresh mass of fruits has showed a high positive correlation with the fresh mass of seeds for the eight evaluated peach rootstocks. The GSI and MGT have a high relationship with the fresh mass of seeds.Index terms: Rosaceae, morphobiometry, seeds, cultivars, peach.Correlação de características biométricas de frutos e sementes com a germinação e vigor de porta-enxertos de Prunus persica RESUMO -Objetivou-se determinar e correlacionar as principais características morfométricas de frutos e sementes sobre o potencial de germinação e o vigor de oito porta-enxertos de pessegueiro. O delineamento experimental foi inteiramente casualizado com quatro repetições de 50 sementes por tratamento. As variáveis analisadas foram: comprimento, largura, espessura, massa fresca dos frutos e sementes, grau de umidade de sementes, porcentagem de sementes intactas e infectadas por fungos, porcentagem de germinação, índice de velocidade de germinação (IVG) e tempo médio de germinação (TMG). As cultivares Capdeboscq, Aldrighi e Tsukuba 1 apresentaram maiores valores médios de comprimento, largura, espessura e massa fresca de sementes comparados com as demais cultivares, apresentando relação com o período mais tardio de maturação dos frutos. Independente da época de maturação dos frutos, a porcentagem de germinação foi alta variando entre 93% e 100% para todas as cultivares. Somado a isso, a massa fresca do fruto apresenta alta correlação positiva com a massa fresca das sementes dos oito porta-enxertos de pessegueiro avaliados. O IVG e o TMG possuem alta relação com a massa fresca das sementes.

“…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.
