Abstract

The acid lime Tahiti is one of the most important fruits produced in the Northwest region of São Paulo state. In 2015, prices and sales surprised with the big high, arousing interest in producing for the expansion of commercial plantations. But there are always losses for producers due to various diseases and pests existing. To reduce these losses, one should use appropriate rootstock to the scion variety chosen. So rootstocks for citrus, are used to provide good agronomic characteristics of scion varieties, as they influence in their development, production precocity, ripening period and fruit weight, absorption capacity, synthesis and utilization of nutrients, salt tolerance, resistance to drought and cold, resistance or tolerance to diseases and pests, among others. The literature reports a small number of works carried out with rootstocks for acid lime Tahiti. Therefore, this study aims to evaluate the canopy compatibility between scion and rootstocks, vegetative development and production of plants, physicochemical characteristics of fruits, drought tolerance in acid lime Tahiti, in a nucellar clone of Tahiti, called IAC- 5. The IAC-5 clone, grafted in seventeen citrandarins (Sunki mandarin x Poncirus trifoliata hybrids) along with the Rangpur lime, the Swingle citrumelo, the trifoliate Flying Dragon and the Sunki mandarin, was planted in an experiment at the Pólo Centro Norte Pindorama, in March 2013, in the city of Pindorama, SP.
