Abstract

A laboratory experiment was conducted in the Department of Biology, Faculty of Education (Saber) – Aden University, to evaluate the effect of Five different concentrations of mannitol solution (i,e., control, 0.5%, 1.0%, 1.5% and 2.0%) on germination and growth of three cultivars of Sorghum bicolor L. i.e., "HAIQ", "BAINI" and "SAIF". The results showed significant differences between the three cultivars for all studied parameters except for the root dry weight mg./seedling. The cultivar "HAIQ" was the most tolerant one, then the cultivar "SAIF", whereas the cultivar "BAINI" was the least tolerant one (95%, 92.1% and 89.4%, respectively). The cultivar "HAIQ" has been the most tolerant as compared to the other two cultivars in several studied parameters, i.e., root length, shoot length, root fresh weight, shoot fresh weight, root dry weight, shoot dry weight. The germination and growth parameters were significantly inhibited with the increase of the concentration of the mannitol solution as compared to the control. The factor interaction for different cultivars and different mannitol concentrations (cultivars x mannitol treatments) was significant for all studied parameters, except for root length (cm./seedling) and root dry weight (mg./seedling).
