Postharvest Quality and Shelf Life Management

Vegetative growth, yield, and fruit quality of 'Fallglo' and 'Sunburst' mandarins on 'Rangpur' lime, 'Swingle' citrumelo, 'Orlando' tangelo, and 'Cleopatra' mandarin were evaluated under subtropical climate of Northern São Paulo State, Brazil, from 2000 through 2006 harvest seasons. 'Fallglo' mandarin trees had the highest cumulative yield on 'Rangpur' lime, and the smallest on 'Swingle' citrumelo and 'Orlando' tangelo. Plants of this cultivar had the highest yield efficiency on 'Rangpur' lime, and the lowest on 'Orlando' tangelo. 'Sunburst' mandarin trees began to bear fruits later than 'Fallglo' mandarin trees, with no differences in yield induced by the rootstocks. 'Cleopatra' mandarin induced the most vigorous growth in 'Fallglo' mandarin as compared to plants on 'Swingle' citrumelo. On the other hand, the largest trees of 'Sunburst' mandarin were registered on 'Orlando' tangelo, and the smallest on 'Rangpur' lime. 'Sunburst' mandarin had higher alternate bearing than 'Fallglo' regardless the rootstock. Fruit weight and juice content were not affected by the rootstock. These two mandarin scion cultivars may be considered adequate alternatives to produce good fruit quality for the fresh fruit market. 'Cleopatra' mandarin and 'Rangpur lime are suitable rootstocks for 'Fallglo' mandarin, whereas all rootstocks evaluated are adequate for 'Sunburst' mandarin.
