摘要

/ha. The plot TC (50 olive trees) was not amended and served as a control. After one year of OMW application, at harvest, olive fruits were collected and pomological characteristics were determined. Olive oil was extracted and biochemical parameters were studied. Statistical analyses showed that short-term field application of OMW affected negatively carpometric characteristics of olive fruits and oil content. Oil produced from TM had a decreased pigment content and oxidative stability. Moreover, the level of MUFA, particularly oleic acid, as well as C18:1/C18:2 and MUFA/PUFA ratios were negatively influenced by OMW amendment which affects negatively olive oil quality and nutritional value. These findings must be taken into consideration when developing strategies for oil quality enhancement, especially in an exporting country like Tunisia.
