Figures & Tables

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.

Illustration of 'Keitt' (A), 'Palmer' (B), 'Kent' (C), and 'Tommy Atkins' (D) mango scions grafted onto 'Espada', 'Capucho', and 'Coquinho' rootstocks at 227 DAG. DAG, days after grafting.

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.

Starch content in the fresh mass of 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.

Net photosynthesis (A), stomatal conductance (B), internal CO2 concentration (C), and transpiration rate (D) of 'Keitt', 'Palmer', 'Kent', and 'Tommy Atkins' mango scions grafted onto 'Espada'. 'Capucho' and 'Coquinho', 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.

Instantaneous carboxylation efficiency (CEi) 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.

Summary of analysis of variance (‘F’ value) for net photosynthesis (A), stomatal conductance (gs), internal CO2 concentration (Ci), transpiration rate (E), WUEi, and instantaneous carboxylation efficiency (CEi) as a function of different rootstocks (R) and scion cultivars (S) of mango during its scion phase_
