Caracterização físico-química dos frutos da limeira ácida ‘Tahiti’ em porta enxertos sob estresse salino.

Abstract

Salinity is a limiting agent, so the choice of genotypes for application in orchards has been a great possibility to understand resistance to saline stress, especially regarding the quality of the fruits. Therefore, the objective was to evaluate the quality of the fruits of different genotypes of the acidic lime tree 'Tahiti' under two levels of salinity. The fruits were harvested in the experimental area of the Center for Science and Agrifood Technology at the Federal University of Campina Grande, Pombal, Paraíba, Brazil, being selected, classified and discovered in the analysis. A completely randomized design was used, in a 2 x 10 factorial scheme, the first factor being: different levels of electrical conductivity (0.3 and 3.0 dS m-1) and the second factor, genotypes. Fruits irrigated with 0.3 dS m-1 stood out from those with 3.0 dS m-1, especially the TSKC x (LCR x TR) - 017 genotype. As for the physical-chemical characteristics, the highest qualitative expression was obtained in the genotype TSKC x (LCR X TR) - 059.
