“…These declines occurred for different reasons and were strongly offset by increases in production in the other tree fruit described above. Quince was a critical industrial crop in the 1930s in the Serra da Mantiqueira region of Minas Gerais State, Brazil (Bettiol Neto, Pio, Sanches, Chagas, Cia, Chagas, and Antoniali, 2011). Pear and olive production has gradually declined because of a marked decrease in the supply and quality of the produced fruits in relation to fruits produced abroad (Pio et al, 2007).…”

The present study aimed to review the advances in the production of temperate fruits to determine future research directions that improve production in the tropics. Temperate fruits are no longer only produced in regions characterized by a cold winter period. These fruits are also produced in the sub-tropical and tropical regions characterized by mild winter or even the absence of chilling conditions often required by the tree to break dormancy. Currently, temperate fruit production is possible in certain regions of South America, Africa and Asia that are near to the Equator. However, temperate tree fruit production in tropical regions requires modified techniques to overcome dormancy and allow adequate flowering, growth and productivity. The main approaches taken are the development of cultivars with low chilling requirement, chemical induction of budbreak, interruption of irrigation during the winter period, defoliation, orchard densification, and double pruning. Breeding has become a key tool in the advancement of temperate fruit growing in the tropics, especially with the development of low chilling requirement cultivars.

“…However, Pyrus rootstocks provide very vigorous crowns, which makes it difficult to conduct plants in high-density orchards (Bettiol Neto et al, 2014). Nonetheless, rootstocks of the Pyrus genus could be an option to provide vigor for quince cultivars, considering that some of them have a slow initial development in the early post-planting years, when propagated by cuttings or grafting (Bettiol Neto et al, 2011), and others have low-rooting capacity (Celant et al, 2010).…”

-The objective of this work was to evaluate the graft growth and the anatomical characterization of pear (Pyrus communis x P. pyrifolia) and quince (Cydonia oblonga) cultivars grafted on Pyrus calleryana and Chaenomeles sinensis rootstocks. Sprouted graft percentages at 60 days and the length and diameter of the graft sproutings at 120 days were evaluated. Stem cuttings from the grafting region were performed in transversal and longitudinal sections, and the secondary xylem was separated for tissue comparison. The pear trees showed good development on P. calleryana rootstock, and the anatomical sections showed that the vascular tissues were connected, which did not occur when the trees were grafted on C. sinensis, in which the grafts sprouted, but did not develop, and the vascular tissues did not connect. The quince trees showed good development on both rootstocks due to the good connection of the vascular tissues. The connection of vascular tissues is essential for the success of grafting. The evaluated species did not differ significantly as to their secondary xylem tissues. The incompatibility found between the pear trees and the C. sinensis rootstocks is not anatomical.Index terms: Cydonia oblonga, Pyrus communis x P. pyrifolia, intergeneric grafting, interspecific grafting, plant anatomy, vascular connection. Compatibilidade anatômica de pereiras e marmeleiros enxertados nos porta-enxertos Pyrus calleryana e Chaenomeles sinensisResumo -O objetivo deste trabalho foi avaliar o crescimento dos enxertos e a caracterização anatômica de cultivares de pereira e marmeleiro enxertadas nos porta-enxertos Pyrus calleryana e Chaenomeles sinensis. Foram feitas avaliações quanto às percentagens dos enxertos brotados aos 60 dias e quanto ao comprimento e o diâmetro da brotação dos enxertos aos 120 dias. Cortaram-se porções caulinares da região da enxertia, em seções transversais e longitudinais, e o xilema secundário foi separado para comparação dos tecidos. As pereiras apresentaram bom desenvolvimento sobre o porta-enxerto P. calleryana, e os cortes anatômicos apresentaram tecidos vasculares conectados, o que não ocorreu quando as pereiras foram enxertadas em C. sinensis, em que os enxertos brotaram mas não se desenvolveram, e os tecidos vasculares não se conectaram. Os marmeleiros apresentaram bom desenvolvimento em ambos os porta-enxertos, em razão da boa conexão dos tecidos vasculares. A conexão dos tecidos vasculares é fundamental para o sucesso da enxertia. As espécies utilizadas não diferiram significativamente quanto a seus tecidos do xilema secundário. A incompatibilidade encontrada entre as pereiras e o porta-enxerto C. sinensis não é anatômica.Termos para indexação: Cydonia oblonga, Pyrus communis x P. pyrifolia, enxertia intergenérica, enxertia interespecífica, anatomia de plantas, conexão vascular.

“…Isso devido ao início da safra nessas regiões ocorrer em época antecipada, em relação às tradicionais regiões produtoras do Rio Grande do Sul e Santa Catarina (ARAÚJO et al, 2008). Essa precocidade de maturação é decorrente do clima hibernal mais quente, o que possibilita efetuar a poda e a indução da brotação das gemas com produtos químicos ainda no inverno, por não haver riscos de geadas tardias (BETTIOL NETO et al, 2011).…”

“…Devido à carência de cultivares adaptadas às condições climáticas de São Paulo, a pomicultura deixou de ser expressiva. Assim, há necessidade de selecionar-se cultivares de baixa necessidade de frio para as condições paulistas, principalmente no Leste do Estado (BETTIOL NETO et al, 2011). Além do mais, é necessário ter outras opções de cultivares além da 'Eva', devido à necessidade de se alocar plantas polinizadores nos pomares de maçã (PETRI et al, 2011).…”
