MERINO-HERNANDEZ, Yanitza et al. Ion accumulation and tolerance to salinity in differentcuban chickpea cultivars (Cicer arietinum L.). cultrop [online]. 2018, vol.39, n.4, pp. 42-50. ISSN 1819-4087.

Chickpea (Cicer arietinum L.) is considered a species sensitive to salinity, but there are differences in the degree of tolerance to this type of stress. The present study was carried out to determine the tolerance to salinity of some cuban cultivars of chickpea and its relationship with indicators of the development and accumulation of ions in the different organs of the plant. For this, eight chickpea cultivars exposed to two treatments, 0 and 50 mM NaCl, were studied. The results showed that the cultivars Nac-29, Nac-5HA and JP-94 were the ones that showed the highest degree of tolerance to salinity. The cultivar N-29 turned out to be more tolerant and although it diminished its growth, the results show that it also accumulated less quantity of ions in the different organs of the plant, in the two conditions of imposed salinity. Therefore, it can be inferred that the reduction in growth was related to some inability of the chickpea plants to prevent high concentrations of saline ions from reaching the leaves, resulting in considerable variability in the degree of tolerance to salinity the cultivars evaluated
