The idea of using medicinalplants to treat human beings and livestock is not new , and in many developing countries their use is still in vogue . Despite thefact that in developed countries modern development in allopathic medicine is at climax , there is a renewed interest in usingmedicinal plants to treat humans , pets and livestock . Medicinal plants are being used for therapeutic purposes in several ways .In modern medicine , many drugs are used that are mainly derived from plants , e .g . digitalis , morphine , atropine , cinchonaand vinblastine ( Joshi , ２０００) . Many people are turning to alternative medicine , due largely to the fact that there are frequentside effects to be faced by taking powerful synthetic allopathic drugs ( Rojhan , ２００３ ) . Because of salinity problems , researchersare trying to get the salt resistant vegetables and medicinal plants on which human摧s food and healthy depend . The presentstudy was carried out to investigate the extent of salinity on the germination and early seedling grow th of Cichorium intybusfrom Compositae .Materials and methods The seeds of Cichorium intybus were used in this study . Experiment was conducted to examine the effectof different NaCl concentrations on germination percentage , germination velocity , root and shoot length and seed vigor . Toevaluate salt tolerance during germination , ２０ seeds were placed on filter paper ( top of paper procedure) and submerged in ５ mlof NaCl . Solutions of NaCl were used at concentrations of ０ ( control ) , １００ , ２００ , ３００ , and ４００ mM . Experiments wereperformed in a completely randomized design with ４ replicates . Germination counts were made daily and were considered tohave germinated when the radicle emerged . At the end of the germination period , the germination percentage , germinationvelocity , length of the stem and root and seed vigor were calculated .Results and discussion Table １ shows the results of NaCl salt effects on germination percentage , germination velocity , length ofstem and root and seed vigor . As it is shown in the table , all of understudy characteristics decrease with increase of salinitylevels .Table 1 Di f f erent NaCl salt concentration on early developmental stage in Cichorium intybus .SourceofVariation Germinationpercentage Germinationvelocity Seed vigor Length of stem( cm) Length of radicle ( cm)０ ( mM ) ９７a ２３ 8.４a ８５ M.８４a １ 3.５２a ７ H.３a１００ =９６a ２２ 8.５a ６６ M.９６b １ 3.２２b ５ H.８b２００ =８８b １７ 8.９５b ２６c ０ 3.６２c ２ H.３c３００ =４６c ３  .６４c ２ .３４d ０ 3.３２d ０ H.１８d４００ =１０d ０  .０９d ０d ０e ０dMeans within a column that have a different small letter are significantly different from each other .In this study , ex tension of NaCl resulted in unsuitable condition for seed germination of medicinal plant . Decrease ofgermination associated with salt concentration increase could be related to accumulation of different ions around seeds whichsubsequently leads to less water absorption by seeds . Water , as well as temperature is of high importance in seed germination .Grieve and Suarez (１９９７) suggest that high levels of soil salinity can significantly inhibit seed germination and seedling grow th ,due to the combined effects of high osmotic potential and specific ion toxicity .ReferencesGrieve C .M , Suarez D .L .
