Abstract: 

Background and objectives: Black cumin is one of the important and valuable medicinal plants and, due to its frequent application in the pharmaceutical industry, is cultivated in different parts of Iran. Limiting environmental factors, however, have a negative impact on its growth and production. Water deficit is one of the main inhibitors for crop production in Iran and many arid and semi-arid regions. Production and potential yield of black cumin also can affect by drought stress. There are not many reports available about drought tolerance of black cumin. Therefore, this research focused on response of ten black cumin landraces to water-stress condition.
Materials and methods: In order to study the effects of water deficit stress on morpho­ physiological traits including oil and grain yield of black cumin an experiment was carried out in Abadeh (Fars province) in 2014. The experimental design was split plot based on complete randomized blocks design with three replications. Water-stress and well-watered conditions as main factor and 10 black cumin genotypes were used as sub-factor. Water deficit stress applied during seedling to ripening stages. Plant height, number of lateral branches, number of follicles per plant, number of seeds per follicle, number of seeds per plant, 1000 grain weight, grain yield, oil content, oil yield, proline content, total soluble sugars and potassium content of black cumin genotypes were measured in both stress and non-stress conditions. Descriptive statistic parameters for all the above measured traits and stress tolerance index (STI) for oil and grain yield were calculated.
Results: Analysis of variance showed that the effect of irrigation for all the measured traits, genotype effect for the most of traits except the number of follicles per plant, grain yield, oil content percentage, proline and total soluble sugars contents, and interaction between irrigation and genotype for all traits except grain yield, oil yield, and proline content were significant. Arak genotype had the highest values for plant height, seed number per follicle, number of seeds per plant and potassium content in water-stress condition. Classification of genotypes using three-dimensional plots of stress tolerance index, stress and non-stress oil and grain yields showed that Arak and Indian landraces were tolerant genotypes in terms of grain and oil yields, respectively. Stress intensity results indicated that proline content and number of lateral branches (SI=0.59) more affected by drought stress.
Conclusion: In this investigation, the all morpho-physiological traits of black cumin affected by water deficit stress. There was enough genetic diversity for drought tolerance among the studied black cumin landraces based on important traits such an oil contention. So, based on these results, it is possible the water deficit tolerance of black cumin crop pine in regions under water stress. These results can be used in breeding programs to improving drought tolerance of black cumin.
