Average concentration of total Na and soluble Cl– in the whole plant and values of Na absorption (AF) and retention (RF) factors for the six different plant combinations: non-grafted pumpkin (P), self-grafted pumpkin (P/P), melon grafted on pumpkin rootstock (M/P), non-grafted melon (M), self-grafted melon (M/M), and pumpkin grafted on melon rootstock (P/M)
