Abstract :

Environmental stresses , drought and salinity are important factors in reducing the yield . Various aspects of the impact of salinity on growth and reduced and delayed germination, reduced vigor, reduced shoot growth and biomass production is reduced . Check -critical power plants against various stresses such as salinity key factor in the success of mass cultivation of plants. In this study, vigor index Tuesday herb Arcitum lappa ( burdock ), Artemisia absinthium ( wormwood ) and Cichorium intybus ( chicory ) under salinity treatments of 0, 100 , 200 , 300 and 400 mM NaCl in a completely randomized design with four replications ofcontrol treatment ( salinity ), respectively. results obtained indicate that the highest level of vigor index of Cichorium intybus and equal treatment 0 to 85.84 percent. , but the character of the house has been treated with 300 mM after seed vigor is almost zero . generally can be studied species in terms of seed vigor under saline conditions cited as follows : Cichorium intybus> Artemisia absinthium> Arcitum lappa In fact, most of the species Cichorium intybus bodied than others, and so Arcitum lappa most weak in terms of salinity and the lowest viability for germination.
