Lycopene and flesh colour differences in grafted and non-grafted watermelon

Open access

Abstract

The experiment was carried out in three regions in Hungary (Jászszentandrás, Cece, Újkígyós) in 2013 to determine the fruit quality of grafted watermelon (Citrullus lanatus Thunb.). The “RX 467” seedless watermelon variety was grafted on two commercial rootstocks “FR STRONG” [Lagenaria siceraria (Mol.) Standl.] and “RS 841” (Cucurbita maxima Duchesne × Cucurbita moschata Duchesne). The lycopene and flesh colours are important quality characteristics even of the selfrooted and grafted watermelon. Some differences can be attributed to different environments, technological methods and to the type of rootstockscion combination. Lycopene is a strong antioxidant; therefore, we considered to examine the content change. Regardless of growing location, the lycopene concentration and the chroma (C*) showed the best result in the case of interspecific rootstock. The result also showed that in two regions (Jászszentandrás, Cece) we can find negative correlation between the lycopene concentration and the L* value of the flesh colour.
