Fig. 1. Relationship between new root weight (g) (NRW) and total seedling weight (g) (TW) in Quercus ilex for the different Inoculum level used. Different letters by the regression lines indicate significantly different slopes. C (control): solid diamond; D1 (dose 1): solid circle; D2 (dose 2): hollow diamond; and D3 (dose 3): hollow circle.

Fig. 2. Relationship between new root weight (g) (NRW) and total seedling weight (g) (TW) in Quercus suber for the different Inoculum level used. Different letters by the regression lines indicate significantly different slopes. C (Control): solid diamond; D1 (dose 1): solid circle; D2 (dose 2): hollow diamond; and D3 (dose 3): hollow circle.
