ﺮرﺳﻲ ﺗﺤﻤﻞ ﺑﻪ ﺷﻮری در ﻣﺮﺣﻠﻪ ﺟﻮاﻧﻪزﻧﻲ در 28 ﺗﻮده ﺑﻮﻣﻲ ﮔﻴﺎه داروﻳﻲ زﻧﻴﺎن(Carum copticum (L.) C. B. Clarke)

In this experiment the effects of salinity stress on 28 native accessions of Ajwain was evaluated. The Experiment was carried out in university of Tehran, abureihan in December 2013. The Experiment was laid out factorial based a completely randomized design with three replications. Levels of salinity were (0, 50, 100, 150 mM of NaCl) and other factor was 28 native accessions of Iranian Ajwain. Results showed that the effects of salinity and different native accessions on all of variant were significant (p<0.01). Interaction effect of salinity and accessions for percentage, rate and energy of germination and biomass and seed energy and dry weight shoot was significant (p>0.05). With increasing of salinity levels percentage, rate and energy of germination, root and shoot length decreased. Yazd accession had the most energy of germination under normal condition. Karaj accession had the most percentage of germination under normal condition. Sarbishe accession had the most root fresh weight under normal condition while the most shoot fresh weight under 100 (mM) salinity level was belonged to Ghom accession.
