Desempenho produtivo e características agronômicas de cultivares de marmeleiro e pereira em Jundiaí - SP

Abstract

Considering the low average production of quince and pear tree in regions of mild winter, the present work was developed in order to select productive cultivars for São Paulo state and evaluate the productive performance and post-harvest quality of the fruits. For such, an experiment of cultivar selection was implemented in the Jundiaí city, SP, with thirteen quince cultivars (Marmelo Pêra, Smyrna, Cheldow, Van Deman, Meliforme, Portugal, Provence, Mendoza Inta-37, Rea´s Mamouth, Fuller, Meech Prolific, De Patras and Pineapple) and five pear cultivars (Centenária, Triunfo, Primorosa, Seleta and Tenra). The evaluations had been carried through in two vegetative cycle (2008/09 and 2009/10), for quinces and three vegetative cycle (2009/10, 2010/11 and 2011/12) for pears, analyzing the phonological aspects, productive and quality post-harvest of the fruits. The plants in early evaluations were with three years for both species. The quince 'Fuller', 'Smyrna', 'Portugal', 'Provence' and 'Mendoza Inta-37' showed higher productive performance. The quince ‘Mendoza Inta-37’ showed quality attributes most suitable for the fresh market, i.e., higher soluble solids content, lower titrable acidity and pulp firmness and ratio highest, followed by quince ‘Fuller’, ‘Provence’, and ‘Portugal’. The ‘Tenra’ pear showed higher productive with 6 kg of fruit per plant. The cultivars produce fruits with coloring typical of the cultivar and firmness acceptable. The ‘Centenária’ pear showed higher ratio soluble solids/titrable acidity (38.43).
