Abstract
Combat of salinity and the major issues it has brought with human struggle have been on for several thousands of years. In this way, the stress caused by it resulted to a reduction of the agricultural production capability of the outlined land. To evaluate the effects of different levels of salinity on the germination of four lentil cultivars (Kabralyaaynta, Philip 97-1L, ILL6199 and Gachsaran), a factorial experiment was conducted in a completely randomized design with 3 replications in the laboratory seed physiology of the State University of Bojnourd (Iran) Branch. Five levels of salinity treatments (0, 3, 6, 9 and 12 ds/m) were derived with the use of sodium chloride salt. The seeds planted in plastic containers with dimensions 5 × 8 × 11 cm were performed and these results showed that the speed and percent germination of all cultivars increased in salinity. Other parameters measured included length of root and stem and the decrease of salt concentration in the solution, if the dry weight of cotyledons in low salinity levels (from zero to 6 ds/m) decreased and increased in level. Among the cultivars studied, Gachsaran figure, when compared with other cultivars in terms of most parameters, was affected by salinity.
Key words: Salinity, percentage of germination, length of root and stem, lentil.
