Effect of gibberellic acid and kinetin on some morphological features in two lentil cultivars under salinity stress

An experiment was conducted to study the effect of two plant growth regulators (gibberellic acid and quintine) on seed germination and initial growth of seedlings and tolerance to salinity in two cultivars of Kimia and Shirvan. This experiment was conducted as factorial with a completely randomized design. Statistical analysis of the studied traits at germination stage and seedling growth showed that salinity reduced the rate of germination and seedling growth in both cultivars. The results of the experiment showed that the inhibitory effect of salt on seedling growth of Shirvan locality was significantly higher than that of Kimia, which in fact indicates the similarity of salinity tolerance in germination stages and complete planting in these two cultivars. Gibberellic acid increased germination speed in both cultivars, but the Kimia genotype was the highest mean for traits (root length, seedling length, root ratio with shoot). But local genotype Shirvan had the highest average in the study of traits such as (relative water content, texture water content, shoot length, number of roots).
