Abstract

Soilless cultivation systems (SCS) are increasingly used toproduce high quality baby-leaf arugula, appreciated by consumers for itspungent taste, due to the content of glucosinolate (GLS). Given all ofthe health benefits attributed to GLSs, there is great interest inunderstanding whether and how soilless growing systems may affect the GLSprofile of arugula. For this purpose, a study was conducted to comparethe GLS profile of Diplotaxis erucoides, D. tenuifolia, and Eruca sativagrown side-by-side under protected environment in a conventional soilsystem(CSS) and in a SCS. Genotype and growing-system resulted in asignificant effect on GLS content, while the resulting qualitative GLSprofile was species-specific. Despite the growing-system, six differentGLSs were identified from plants of D. tenuifolia and E. sativa, whileonly sinigrin was detected in plants of D. erucoides. Total GLS contentwas on average 9.85, 8.23, and 7.96 mg g-1 of dry weight in D. erucoides,D. tenuifolia, and E. sativa, grown in CSS, respectively. The same threespecies grown in SCS synthesised 36%, 51%, and 41% more GLSs than plantsgrown in CSS, respectively. Soilless cultivation may be adopted toincrease the GLS content and enhance the nutritional quality of Brassicasleafy vegetables.
