This research had the objective to evaluate the performance of irrigated and non-irrigated ‘Tahiti’ lime trees grafted on 12 rootstocks and one interstock. Plots were distributed following a randomized block design, with four replicates and one plant per plot. Rootstocks influenced plant vigor, especially ‘Flying Dragon’ trifoliate, which reduced tree height by approximately 47% compared to the ‘Rangpur’ lime. Trees that were budded on more vigorous rootstocks showed higher yield when grown without irrigation than with irrigation. The ‘1646’ citradia and ‘Morton’ citrange rootstocks performed particularly well. On the other hand, the plants on less vigorous rootstocks showed better performance in terms of yield under irrigation than the same combinations without irrigation, especially those grafted on the tetraploid ‘Carrizo’ and ‘Troyer’ citranges, ‘Swingle’ citrumelo, ‘Davis A’ trifoliate and ‘Flying Dragon’ trifoliate. Plants budded on the ‘1708’ citradia had high yields under irrigated and non-irrigated conditions. The effect of interstock on plant vigor was dependent of rootstock. Interstocked plants on ‘Davis A’ trifoliate were higher than those without interstock. On the other hand, interstocked plants on Catania 2 ‘Volkamer’ lemon were less vigorous than those without interstock.► Invigorating rootstocks grown without irrigation induce high yield. ► Yield varies between irrigated and non-irrigated groves. ► Trifoliata ‘Flying Dragon’ is a suitable rootstock for high density ‘Tahiti’ lime.

Osbeck), 'Fortune' (Citrus clementina Hort. ex Tan. x Citrus tangerina Hort. ex Tan.) e 'Nova' [(C. clementina) x (Citrus paradisi Macf. x C. reticulata)] mandarins budded on 'Rangpur' lime (C. limonia Osbeck), 'Swingle' citrumelo (P. trifoliata Raf. x C. paradisi Macf.), 'Orlando' tangelo (C. reticulata Blanco x C. paradisi Macf.), and 'Cleopatra' mandarin (Citrus reshni Hort. ex Tan.) were evaluated, from 2000 to 2006. The experiment was installed in Bebedouro, SP, Brazil, in 1997. Data collected included: annual and total accumulated fruit production in all cultivars for all years (2000-2006), fruit quality in 2005 and 2006 (fruit mass, total soluble solids, total acids, ratio), scion volume, scion trunk diameter, yield efficiency (Kg fruits/m3 scion), and alternate bearing index. Cumulative yield and fruit quality of all cultivars were not influenced by the rootstocks. 'Swingle' citrumelo induced reduced size trees in most of scion cultivars. 'Nova' tangelo has adequate characteristics and potential as a fresh fruit market cultivar. 'Swatow' mandarin had similar fruit quality with those of 'Ponkan' mandarin. 'Ellendale' tangor and 'Fortune' tangerine had low and irregular yield.

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.
