Salinity in rose production

The rose is one of the most important ornamental plants in the world. However, the cultivation systems used for roses often impose salt stress. Saline conditions occur naturally in some regions or by human activity in others with use of low quality water or excessive fertilizer application. In general, roses are considered sensitive to salinity. However, tolerance levels can be different among roses species and cultivars. Therefore, studies are needed that take into account characteristics of each species and how the exposure to salinity occurs. Management of water and nutrients can be important tools for mitigating the effects of high salt concentrations. Also, advances in biotechnology can be used for a better understanding of the physiological responses to salinity and to develop more salt tolerant rose cultivars. Thus, this paper aims to review the progress made and future prospects of salinity tolerance in commercial rose production.
