“…Positive and moderate correlations were obtained between the fruit length and seed length variables (0.55) and between fruit width and seed thickness (0.57) (Table 4); it is considered moderate correlation when the correlation coefficient varies from 0.5 ≤ r < 0.7 (Santos, 2010). This result is similar to the one reported by Dresch et al (2013), who observed a positive and moderate correlation between the fruit width of Campomanesia adamantium (Cambess.) O. Berg (Mirtaceae), with the seed thickness.…”

“…Researches conducted with fruit and seeds of species from different botanical families such as majestic heaven lotus (Gustavia augusta L., Lecythidaceae Family) by Silva et al (2014), cucumber tree (Averrhoa bilimbi L., Oxalidaceae Family) by Santos et al (2015), and Campomanesia adamantium (Myrtaceae Family) by Dresch et al (2013), indicated that longer and wider fruits presented higher values of fruit mass and seeds. Similar results were obtained in the present study, where the three rootstocks presenting higher values of fruit mass (Table 1) were also the ones presenting seeds with bigger dimension and seed fresh mass (Table 3).…”

-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.

“…These substances are mobilized during germination and during the development of the seedlings their degradation products are used for different purposes, such as generation of energy and the production of raw material for the construction of new cells and tissues. Results are in agreement with DRESCH et al (2013), which worked with Campomanesia adamantium, in which fruits of medium and small size had a higher percentage of germination, while fruits classified as large presented higher accumulation of biomass.…”

Seminiferous propagation in the selection of chestnut tree rootstocks

et al. 2017

Aiming the selection of rootstocks to produce seedlings, the objective of this study was to quantify the seminiferous propagation in chestnut seeds, with or without incisions. Nine cultivars were used (‘Ibuki’, ‘Isumo’, ‘Kinshu’, ‘Moriwase’, ‘Okuni’, ‘Senri’, ‘Taishowase’, ‘Tamatsukuri’ and ‘Tiodowase’) and two selections (‘KM-1’ and ‘KM-2’) of hybrid chestnut trees (Castanea crenata x Castanea sp.). An incision was held in half of chestnuts and the other half remained intact. Percentage of germination, emergence and root length were quantified. The germinated nuts were transplanted and were quantified the diameter and height of seedlings. Then, the chestnut selections ‘KM-2’ and ‘Jacutinga’ were grafted by the cleft grafting method, and were quantified the percentage of sprouting, besides the diameter and height of grafts. Incisions increase the germination and seedling emergence in most cultivars and selections. ‘Taishowase’ and ‘Tamatsukuri’ stood out over the others to germination, growth of the rootstocks.

“…adamantium has interesting traits associated with its domestication, including variation in optimum harvest and consumption times (Santos et al, 2015), seed germination, and seed storage (Dresch et al, 2013(Dresch et al, , 2014. Previous morphological and molecular analyses of genetic diversity based on random amplified polymorphic DNA were conducted using progenies of 140 trees (de Assis et al, 2013).…”

ABSTRACT.We assessed the transferability of 120 EST-derived Eucalyptus microsatellite primers to Campomanesia adamantium and C. pubescens. Both species are berry trees native to the Brazilian Cerrado, and population genetic information is poor. Twelve markers were used to analyze the genetic variability of four sampled populations. Regarding DNA extraction, we sampled leaf tissues from two populations of each species (80 individuals). Of the 120 primers evaluated, 87 did not amplify any PCR products, and 21 rendered nonspecific amplification. Twelve primers were successfully transferred, providing a low combined probability of genetic identity for both species (5.718 x 10 -10 for C. adamantium; 1.182 x 10 -11 for C. pubescens) and a high probability of paternity exclusion (0.99939 for C. adamantium; 0.99982 for C. pubescens). The average number of alleles in the polymorphic loci was 6.8 for C. adamantium and 7.8 for C. pubescens, ranging from 2 to 16 alleles per locus. The observed heterozygosity values for C. adamantium and C. pubescens were 0.504 and 0.503, respectively, and the expected heterozygosity values for C. adamantium and C. pubescens were 0.517 and 0.579, respectively. The populations exhibited structured genetic variability with qP values of 0.105 for C. adamantium and 0.249 for C. pubescens. Thus, we concluded that these 12 microsatellite markers, transferred from Eucalyptus, were efficient for population genetic studies of C. adamantium and C. pubescens.
