“…European pears; conversely, have the capacity to complete the ripening process post harvest. Number of days that lapse between the date of full bloom and harvest point was used as the indicator of the maturation index of the hybrid pear (BETTIOL NETO et al, 2014). The authors reported a mean value of 138 days and fruit length and diameter were estimated, as well as the post-harvest variables including color, firmness, titratable acidity, and soluble solids, besides others.…”

The goal of this study was to elucidate the growth and development of the Asian pear fruit, on the grounds of length, diameter and fresh weight determined over time, using the non-linear Gompertz and Logistic models. The specifications of the models were assessed utilizing the R statistical software, via the least squares method and iterative Gauss-Newton process (DRAPER & SMITH, 2014). The residual standard deviation, adjusted coefficient of determination and the Akaike information criterion were used to compare the models. The residual correlations, observed in the data for length and diameter, were modeled using the second-order regression process to render the residuals independent. The logistic model was highly suitable in demonstrating the data, revealing the Asian pear fruit growth to be sigmoid in shape, showing remarkable development for three variables. It showed an average of up to 125 days for length and diameter and 140 days for fresh fruit weight, with values of 72mm length, 80mm diameter and 224g heavy fat.

“…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.

“…Despite the pear being a fruit from temperate climates, there are some cultivars adapted to a subtropical climate (BETTIOL NETO et al, 2014;TECCHIO et al, 2011); the cultivation of this fruit in regions with mild winters is possible due to hybrid cultivars (Pyrus communis x P. pyrifolia) known as hardy pears. These cultivars were obtained by hybridisation between European pears (high winter cold requirement and excellent fruit quality) and oriental pears (low winter cold requirement and inferior fruit quality), developed in past decades by the Campinas Agronomic Institute (BARBOSA et al, 2007, BETTIOL NETO et al, 2014.…”
