“…It is a cool season food legume that allows early sowing in spring to produce high fresh bean and dry grains under arid and semi-arid conditions (Kelly, 1987). Because pea is particularly sensitive to drought (Wilson et al 1985) and salinity stresses (Lal, 1985) during early growth stages, tolerant varieties provide considerable advantages under these conditions (Dudhe and Kumar, 2018). The pea cultivars had significant variation for salinity tolerance during germination and early seedling development (Cerda et al 1982 andOkçu et al 2005).…”

Background: Salinity is a severe abiotic stress resulting in inhibiting germination, seedling growth of crop plants. Germination performance under salinity depends on seed vigor and genotypic factors. This study aimed to determine if there was a relationship between germination and seedling growth of eight pea cultivars subjected to three chloride salts and the results of seed vigor tests. Methods: Pea cultivars Ambassador, Bolero, Electra, Esprit, Puccet, Rainer, Utrillo and Winner were germinated in the medium with three chloride salts of NaCl, MgCl2 and CaCl2 with the electrical conductivity (EC) of 20 dS m-1. Also germination percentage, mean germination time, controlled deterioration (CD) and electrical conductivity (EC) test were evaluated. Result: The seed vigor of pea cultivars was significantly different and salinity led to a significant decline in parameters of the cultivars. The most hazardous salt was MgCl2, while the least harmful was NaCl. Germination percentage was negatively related with MGT and EC values and EC test was strongly correlated with CD test. Utrillo and Winner were the most sensitive cultivars to MgCl2 and CaCl2. Although germination percentage of Rainer under non-saline was the lowest with 76%, it showed better performance under salinity than Utrillo and Winner. Germination percentage and CD gave a negative significant correlation with NaCl, but MGT and EC associated positively with NaCl. It was concluded that seed vigor should be considered as an indicator for the germination performance of pea seeds under NaCl, whereas genotypic factors play a key factor for tolerance to salinity during germination and early development stages.

“…However, some studies related to the problem were carried out by foreign scientists, and now we can state that salt stress tolerance of the crop could be improved by inoculation of the seeds with Bacillus subtilis (BERA 71) strain of endophytic bacteria (Abd-Allah et al, 2018). And, of course, special work is conducted by plant breeders to discover the best ways, crossing combinations between different genotypes, pointing out salinity tolerance markers in the chickpea genotype to provide the best options for selection of new saltresistant cultivars of the crop (Dudhe & Kumar, 2018).…”

Chickpea (Cicer arietinum L.) is one of the main pulse crops cultivated mostly in the arid and semi-arid regions of the world, very often on saline lands. The problem is that it has not been clearly determined yet what is the safe salinity degree for obtaining uniform and vigorous sprouts of the crop without significant suppression in the parameters of initial growth and development. The goal of our study was to determine the effect of different NaCl concentrations in solutions on chickpea germination and initial growth to determine the safe degree of salinity for the crop cultivation. The study was carried out in greenhouse conditions of Kherson State Agrarian University. We studied the effect of five different gradually increasing degrees of NaCl solutions on the germination percentage and initial growth of chickpea (variety Rosanna, kabuli type) that was germinated in laboratory conditions in flasks filled with sand, at the temperature of 25 oC. A significant decrease in all the studied parameters was observed with the increase of salinity degree. However, we think that a considerable decrease of the crop germination and initial growth started with NaCl concentration of 1.79 g/L: germination percentage decreased by 33.9%, plant height – by 7.8 cm, root length – by 5.5 cm in comparison to the control variant (not saline conditions). Therefore, we conclude that the chickpea can be efficiently cultivated on slightly-saline lands. Besides, the results of linear regression analysis revealed that the most susceptible stage of chickpea growth and development is germination because this stage had strong close inter-connection with the degree of salinity. Further growth of the crop was less affected by the salinity stress. We recommend cultivation of chickpea on the saline lands only with a slight salinity level.
