Abstract:
Perennial wall-rocket (Diplotaxis tenuifolia) belongs to the Brassicaceae family. It has spread worldwide due to its functional properties, and has long been known in folk medicine of native populations in areas of the Mediterranean and western Asia. In the past, Diplotaxis tenuifolia was a herbaceous plant harvested and consumed as a spontaneous herb, but today it is an important leafy vegetable in ready-to-use salads, with an increasing impact in the national and international vegetable retail markets. The leaves of perennial wall-rocket have valuable nutritional properties because of the amounts of antioxidant compounds they contain, in particular glucosinolates, vitamin C, as well as flavonoids, which make their consumption beneficial for preventing some types of cancer and cardiovascular disease. In the current review, major pre-harvest factors of Diplotaxis tenuifolia production, such as cropping systems, fertilization, as well as water management and irrigation, are addressed with respect to crop productivity and leaf quality.
