The plots were planted in 2001 without supplementary irrigation, at 8 × 5 m spacing, using a randomized block design. After 7 years from planting, the ‘Flying Dragon’ trifoliate conferred smallest canopy volume and lowest cumulative yield, while the ‘Orlando’ tangelo induced largest canopy volume, but low cumulative yield. Largest cumulative yields were recorded onto ‘Cravo FCAV’ and ‘Cravo Limeira’ Rangpur limes. In the 2006-2008 period, yield efficiency was significantly higher onto ‘Flying Dragon’. Reduced tree size and high yield efficiency conferred by this rootstock allow its recommendation for high-density plantings. Nevertheless, its low drought tolerance limits its use to irrigated conditions. On the other hand, both Rangpur lime scions and the ‘Sunki’ mandarin induced high tree tolerance to drought. Based on the overall tree performance, a hierarchical cluster analysis identified two groups of rootstocks with similar effects on ‘Tahiti’ lime: (i) both Rangpur limes and (ii) the ‘Changsha’ × ‘English Small’ hybrid and ‘FCAV’ trifoliate. The ‘Flying Dragon’ rootstock had a unique effect over ‘Tahiti’ limes, different from all the other rootstocks, inducing higher yield efficiency, earlier bearing, larger percentage of fruit harvested in the second semester in the internal market, and a larger production of export fruits with larger size, adequate peel color and high soluble solid content.  ahybrids  aFruta Cítrica  aHibrido  aEstresse hidrico1 aSTUCHI, E.
