Figure 1.
PGS (A), PH (B), and RSD (C) of 'Keitt', 'Palmer', 'Kent', and 'Tommy Atkins' mango seedlings grafted onto 'Espada', 'Capucho', and 'Coquinho', at 227 DAG. Bars with the same letters do not differ by Tukey’s at 5% error probability. Bars with capital letters compare data between the rootstock within each scion and bars with lowercase letters compare data between the scion within each rootstock. DAG, days after grafting; PGS, percentage of graft success; PH, plant height; RSD, rootstock stem diameter.

Chlorophyll a(A), b(B), and total(C) indexes and TSC (D) in leaves of 'Keitt', 'Palmer', 'Kent', and 'Tommy Atkins' mango scions grafted onto 'Espada', 'Capucho', and 'Coquinho' rootstocks at 227 DAG. Bars with the same letters do not differ from each other by Tukey’s test at 5% error probability. Bars with capital letters compare data between the rootstock within each scion and bars with lowercase letters compare data between the scion within each rootstock. DAG, days after grafting; TSC, total soluble carbohydrates.

Bars with the same letters do not differ from each other by Tukey’s test at 5% error probability. Bars with capital letters compare data between the rootstock within each scion and bars with lowercase letters compare data between the scion within each rootstock. DAG, days after grafting.
