Abstract
The ‘Frost Nucellar Lisbon’ lemon (Citrus limon (L.) Burm.f.) is one of the most widely cultivated lemon cultivars in Tucumán citriculture.
The objective of this study was to evaluate both qualitatively and quantitatively the behavior of ‘Frost Lisbon’ on different hybrid rootstocks.
The performance of three hybrid rootstocks from the EEAOC breeding program was assessed: Citrumelo 75 AB (Citrus paradisi Macf × Poncirus trifoliata (L.) Raf.), Citrandarin 61 AA3 (Citrus reshni Hort ex Tan × Poncirus trifoliata (L.) Raf.), 81 G 220 (Citrus volkameriana Ten.
Et Pasq. × Citrus reshni Hort. ex Tan), and one rootstock introduced from the USA, Citrange C-35 (Citrus sinensis L. Osbeck × Poncirus trifoliata (L.) Raf.), compared with Citrumelo CPB 4475 (Citrus paradisi × Poncirus trifoliata) on which the lemon tree was grafted.
The trial was established in 2007 in El Tuyango (26°59’14”S, 65°25’14”W) Tucumán, Argentina, in plots of 3 plants with four replications in completely randomized blocks at a spacing of 6×8 m.
The parameters evaluated during the period 2011 to 2024 were yield (kg tree‑1), productive efficiency (kg m‑3), and canopy volume (m3). This last parameter is crucial when analyzing plant size to determine the appropriate planting density.
The hybrids evaluated did not statistically differ from Citrumelo CPB 4475 in cumulative yield; however, C35 and 61 AA3 differed from each other and from the rest in terms of canopy volume, inducing smaller canopies (66 and 71%, respectively) compared to CPB 4475. Regarding productive efficiency, although no differences were observed, rootstocks with lower canopy development could be planted in more compact patterns, leading to increased productivity ha‑1.
