| RESUMO O caquizeiro é propagado por enxertia, em porta-enxertos obtidos por sementes. Devido à baixa germinação, este trabalho teve como objetivo aumentar a obtenção de porta-enxertos dos caquizeiros Dyospyros kaki eDyospyros lotus através da estratificação e tratamento das sementes com ácido giberélico e utilização de diferentes temperaturas ambientais. No primeiro experimento, as sementes foram colocadas entre camadas de areia umedecida em placas de Petri e mantidas em câmara tipo B.O.D. com temperatura de 4 ºC, por 15 e 30 dias, além do controle, onde as sementes foram imersas em água por 10 min. Em seguida as sementes foram colocadas em bandejas plásticas com areia grossa em câmara tipo B.O.D., com temperatura controlada e constante de 15; 20; 25 ou 30... |

| ABSTRACT: The persimmon tree is propagated by grafting and the rootstocks are produced from seeds. Grafting is done in July, which coincides with the time when the persimmon trees are pruned. But, at this time, many rootstocks are not yet eligible to receive the grafts. In this case budsticks/cleft storage is an option. Thus, this study aimed to verify the feasibility of cold storage of budsticks/cleft and verify the grafting method to promote better graft development. Rootstock was sown in August 2012 and the branches were collected in July 2013. Part of the branches was used for grafting (budding and cleft graft methods) in one-year old rootstocks and the other part was stored at low temperature (cuttings wrapped in moistened paper and then wrapped in... |

| ABSTRACT: In recent years "redness" has increasingly appeared in strawberry plants with leaves taking on a reddish color. No causal agent has been associated with plants. Since strawberries presented problems due to the incidence of nematodes, the purpose of this study was to look at the relationship between production, resistance to the Meloidogyne hapla nematode and the "redness" symptom in strawberry cultivars. Two experiments were performed, both with the 'Camino Real', 'Festival', 'Oso Grande', 'Albion' and 'Camarosa' cultivars. The first experiment was performed in the field, where the following were evaluated: strawberry production, fruit quality, macro and micronutrient contents in fruit and leaves, percentage of plant survival, incidence of... |

| ABSTRACT: 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... |

| ABSTRACT: Plum growing is widespread in temperate zones. In Brazil, the exploitation of this fruit tree is extended from the colder regions of the state of Rio Grande do Sul to the south of the state of Minas Gerais. However, cultivars exploited at subtropical regions are scarce due to competition. The present study aimed to select productive cultivars of plums adapted to Brazilian subtropical conditions. In this respect, the plum cultivars ‘Fla 87-7’, ‘Gema de Ouro’, ‘Grancoure’, ‘Harry Pickstone’, ‘Januária’, ‘Santa Rosa’ and ‘Satsuma’ were grafted on the ‘Okinawa’ rootstock ‘and evaluated by two cycles in the municipality of Lavras, MG, Brazil. The phenological development, physical and chemical properties of fruits, average number of fruits per plant,... |
