One of important problem airid and semi-aird regions, existence abiotic stress espically drought and salt stress.  Drought and salt stress have ngative effect on growth and devloment of plant. Drought stress when happen that water recived plant was fewer of water loss. Salt stress also in addition of toxicity to plant, result drought stress in plant. In this study was performed in order to effect drought and salt stress on germination, growth parameter and antioxidant activity enzyme on medical chamomile plant. This study was two sperate experiment in the format completely random design with three repeat were conducted in Labe University of Mohaghegh Ardabili on 2016. Treatments drought stress include 0, -2,-6,-8,-10 and -12 bar and salt stress include 0, 3, 6, 9 and 12 dsm and ten various ecotypes of chamomile. Result induced, salt and drought stress had effect on germination index and result decrase germination percentage, germination rate and germination uniformity, in addition reduced length radical and Plumule on various ecotypes of chamomile. Ecotypes of chamomile could to 12 dsm salt had germination, whiles have done to -4 bar germination.under drought stress.  Protein content and antioxidant catalase peroxidase and polyphenol oxidase had increase significant over control. According to the results, the ecotype of the most resistant ecotype and the ecotype of Kerman were the most sensitive ecotype for salinity and drought stress.
