Citrus is a fruit species commercially in the tropical and subtropical regions of the world. Growth and development of plants are affected by environmental factors such as salinity and drought. Global climate change will increase water stress risk in the near future. One of the purposes of plant biotechnology is the development of plants tolerant to drought. Among environmental stresses, drought stress is one of the factors that negatively affect plant growth and yield. The response of plants to drought stress is quite complex and is the process of many genetic expressions. In this study, Troyer citrange and C-35 citrange from the significant citrus rootstocks were used. After seeds of plant materials were germinated drought stress was applied in in vitro condition. The response of the plants to drought and performance of micropropagation has been determined. It was determined that both rootstocks continued their life and proliferation in increasing PEG doses, however their performance found to be declining. © 2018, Centenary University.
