| Most bivalves species of the genus Pinctada are well known throughout the world for production of white or black pearls of high commercial value. For cultured pearl production, a mantle allograft from a donor is implanted into the gonad of a recipient oyster, together with a small inorganic bead. Because of the dedifferentiation of cells during the first steps of the host oyster's immunological reaction, so far the fate of the graft and its exact role in the process of pearl formation could not be determined via classical histological methods. Here we report the first molecular evidence of the resilience of the graft in the recipient organism by showing that cells containing genome from the donor are still present at the end of pearl formation. These... |

| Objetivou-se avaliar a indução de brotações epicórmicas em cepas e as técnicas de estaquia, miniestaquia e enxertia para a clonagem de Cupressus lusitanica. Para a estaquia, testaram-se concentrações de ácido indolbutirico e substratos em plantas de 5 e 10 anos de idade. Na miniestaquia, avaliou-se o tipo de propágulo. Na enxertia, utilizaram-se propágulos de árvores de 10 anos como enxertos para o primeiro subcultivo, sendo, a partir deste, coletadas as brotações para o segundo subcultivo. A espécie apresentou difícil enraizamento e a enxertia, o melhor resultado. A indução de brotações de cepas apresentou baixa viabilidade.doi: 10.4336/2010.pfb.30.62.161 |

| Abstract: Understanding the mechanisms involved in tree species maturation, related mainly to ontogenetic age effects, has contributed significantly to the vegetative propagation process of Brazilian native tree species, with consequent application of clonal forestry. A number of methodologies has been developed to rescue and vegetatively propagate these species for silvicultural and environmental restoration purposes. However, the types and purposes of propagation, as well as the choice of suitable processes and propagules considering the intended objectives, still need to be better aligned. In addition, there is an evident knowledge gap and great potential regarding the use of native tree species in Brazilian clonal forestry, indicating the need of a... |

| Young sexually and assexually propagated Barbados cherry plants were submitted to water deficit (20 days without irrigation). During this period the accumulation of proline, water potential of branches, osmotic potential, the relative water content of leaves, the leaf diffusive resistance, the transpiration rate and leaf temperature in the cuvette were determined. In addition, photosynthetically active radiation (PAR) and vapor pressure deficit (VPD) were measured in the porometer cuvette. The concentration of proline for both types of plants began to increase on the fifth day without watering, and reached 38.1 times the concentration in the control plants grown from seeds and 26.4 times the concentration in grafted plants on the tenth day without... |

| Abstract In the state of Bahia, Brazil, citrus production is mainly on the Northern Coast region, with major cultivation of ‘Pera’ sweet orange grafted onto ‘Rangpur’ lime. The production of mandarins and mandarin-like fruits is very low in spite of the increasing regional consumption. Varieties that are adapted to tropical sub humid conditions should be evaluated on different rootstocks for cultivation recommendation. This study assessed the performance of ‘Piemonte’ tangor over 14 rootstocks in Rio Real, BA. Planting was performed in 2006 on a cohesive yellow argisol, at 6.0 m x 4.0 m spacing and with no irrigation. Plant growth, production, and physicochemical attributes of fruits in 2010-2014 were assessed, in addition to tree survival and drought... |

| Abstract The propagation of many passion fruit species (Passiflora spp.) is done by seeds or sexual method, although asexual propagation, such stem cuttings, grafting or tissue culture is also possible and very useful in many cases. In this work, it was presented information on scientific and technological advances in sexual and asexual propagation of passion fruit, considering the different propagation methods and their applications. New demands for research and development activities are also related, given the wide range of passion fruit species and its potential for food, ornamental and medicinal use. |

| Abstract The Myrtaceae family has representatives spread worldwide, and Jabuticaba tree is an important species native to Brazil, which is grown not only in the backyards and domestic orchards, but also in commercial orchards, landscaping projects and in several tropical and subtropical countries. The propagation of this species in a sexual form or by seeds is simple and efficient, being able to reach 100%. However, long juvenile phase and genetic segregation have led to the search for methods that allow the propagation of selected trees and guarantee through their standardized and productive clones, fruit quality and fruiting precocity. Protocols for asexual propagation are still scarce, but they show efficient methods, making possible the commercial use... |

| Abstract In Brazil, the main cultivated passion fruit species is Passiflora edulis, which is affected by Fusarium soil fungus. P. mucronata species stands out because it presents resistance to this fungus, being thus an alternative rootstock to yellow passion fruit. Therefore, the aim of this study was to evaluate the anatomy of mini-grafting by top cleft grafting and simple English type grafting, using shoot tips of adult P. edulis plants in clonal rootstocks of P. mucronata. When the rootstocks reached approximately 2.5 mm in diameter and 20 cm in height, grafting was carried out with Parafilm® tape fasteners and silicone clip. At the end of 60 days, histological analysis of the grafting region was performed to verify the formation of the scarring... |

| ABSTRACT The interaction between rootstock, scion and the environment may induce different responses to the grapevine physiology and, consequently, to the grape composition. The vineyards of Serra Gaúcha, Brazil, are established in different soil types, each with different morphological and physicochemical attributes. Moreover, the grapevines are grafted onto a diversity of rootstocks. Therefore, this study aimed to determine the effect of 15 rootstocks in the composition of the Cabernet Sauvignon (CS) grape must. The following rootstocks were used: Rupestris du Lot, 101-14 Mgt., 3309 C, 420A Mgt., 5BB K, 161-49 C, SO4, Solferino, 1103 P, 99 R, 110 R, Gravesac, Fercal, Dogridge and Isabel, featuring some genetic diversity altogether. The experimental... |

| Abstract The vegetative propagation in cacao has been used in Central America since the beginning of the last century. However, only from the end of the century this technique has been intensified in the state of Bahia, where vegetative propagation changes have increased the yield of cocoa growing areas, especially those using other technologies associated with clonal seedlings. The use of clonal garden to collect stems in nursery can reduce by 80% the space required for maintenance of stock plants. On the other hand, the buds obtained from orthotropic and plagiotropic shoots are used to improve the performance protocols and reduce production costs of seedlings. Among the current and future challenges in the production of cocoa seedlings emphasizes the... |

| Abstract Apple production has been an important economic activity worldwide. The wide dissemination and cultivation of apple trees in several regions of the world is due to the development of propagation techniques from its domestication to the present time. Apple trees can be propagated by seeds, restricted to the use in breeding programs, and multiplied by several methods of vegetative propagation, both for rootstocks and apple scion cultivars. Considering the high technological level currently used in apple crop management, plant propagation plays a very important role in order to enable seedling production with high morphological quality and free of diseases, requiring new advances and propagation improvements in new releases of rootstocks and apple... |

| ABSTRACT The interaction between rootstock, scion and environment can induce different responses to the grapevine physiology. Thus, the aim of this study was to determine the rootstock effect on the yield components of Cabernet Sauvignon (CS) grapevine grown in the Serra Gaúcha viticultural region. The experimental design was completely randomized blocks, with 15 treatments, three replicates and ten vines per plot. The results show that all variables evaluated were significantly affected by the year and the rootstock. The CS/Solferino was among other combinations influenced by the year and had higher significant yield/ vine. Indeed, it was higher than that CS/Rupestris du Lot, CS/101-14 Mgt., CS/3309 C, CS/5BB K, CS/161- 49 C, CS/1103 P. and CS/Isabel.... |
