| Nutrient resorption is a process of nutrient remobilization from senesced organs to living tissues inside a plant. Since the Northern Territory (NT) has relatively poor soil conditions and a limited supply of plant nutrients, it is crucial to determine suitable scions for efficient macronutrient resorption in the Kensington Pride (KP) mango rootstock. The scions used in this study were NMBP 1201 (T1), NMBP 1243 (T2), NMBP 4069 (T3), B74 (T4), and KP (T5). The experiment occurred in a randomized, complete block design with five treatments and five replicates. The results showed that grafting the B74 scion onto the KP rootstock resulted in trees with reduced canopy area (65.76 ± 4.39b) and volume (48.43 ± 4.92b), indicating its suitability for narrow-planting distance to produce more mangoes in a smaller area. Grafting the B74 scion onto the KP resulted in a larger leaf area (6.52 ± 1.36), ultimately increasing nutrient resorption efficiency, which is beneficial in nutrient-deficient soils like in the NT. NMBP 4069 scions grafted onto the KP rootstock had a larger canopy area (87.47 ± 5.37a) and canopy volume (72.23 ± 6.21a). These trees need more space to grow and have lower nutrient resorption efficiency, owing to their smaller leaf area. The scions NMBP 1201 and NMBP 1243 displayed comparable growth metrics and nutrient resorption efficiency when grafted onto the KP. Scions of the B74 can be highly suitable to withstand diverse environmental conditions, optimize nutrient use, and increase fruit yield on a commercial level. | ||
