Fruit quality of ‘Tahiti’ lime grafted onto different rootstocks grown under salt stress

Abstract

Salt stress is one of the main obstacles to citrus production in arid and semi-arid regions, limiting fruit production and quality, making it necessary to use tolerant genetic materials to improve the quality of citrus production in these regions. The objective of this work was to evaluate the fruit quality ‘Tahiti’ lime grafted onto different rootstocks grown under salt stress and to evaluate different storage days. Three ‘Tahiti’ lime genotypes, two electrical conductivity of irrigation water, and two storage time were studied. Salt stress increased the fruit quality of ‘Tahiti’ lime. Storage for 10 days increases ascorbic acid and soluble sugars, independent of genotype and salt stress, while all genotypes have desirable postharvest fruit quality characteristics. Genotypes 2 and 3 are promising to be cultivated in semi-arid regions, in addition to maintaining the fruit quality in conditions of salt stress. Therefore, grafting is a technique to increase the postharvest quality of ‘Tahiti’ lime grown under salt stress.
