El olivo (Olea europaea L.) y el estrés salinoimportancia de los reguladores del crecimiento

Abstract

Salinity is one of the most important abiotic stresses, causing decrease on plant growth and productivity. Olive is considered as having medium tolerance to salts and this is dependent on cultivar. Thus, selection and use of tolerant cultivars would be a useful means to face salinity problems in the olive culture. In the present work, the mechanism of salt tolerance in six olive cultivars (Casta Cabra, Cornicabra, Frantoio, Ocal, Picual, and Picudo) were studied, particularly in the cultivar Picual. Further, changes caused by NaCl on several growth parameters, gas exchange, chemical composition, and oxidative-stress symptoms have been measured. Also, in this work, the role of some phytohormones in alleviating salinity stress in cultivar Picual has been studied
