Soluble solid content (SSC), dry matter (Dm) and sodium content in ungrafted melon cv. Paloma (M) or grafted onto the resistant rootstock C. metuliferus BGV11135 (GM) cultivated in soil infested with increasing Meloidogyne incognita densities at transplanting (Pi) in a plastic greenhouse during 3 years (2015–2017).

Data are mean ± standard error of 5 replicates. Data in the same column and cropping season followed by the same letter did not differ (P < 0.05) according to the non-parametric Mann–Whitney or Kruskal–Wallis test. Data within the same row per quality parameter followed by * indicate differences between germplasm according to the non-parametric Mann–Whitney test (P < 0.05). n.a: Range of Pi not represented in the treatment; ^†: Pi = 0 included nematode densities below the plant tolerance according to the Seinhorst damage function model.
