Characterisation of Breadfruit (Artocarpus altilis) Plants Growing on Lakoocha (A. lakoocha) Rootstocks

Breadfruit (Artocarpus altilis) is a traditional fruit tree of 15–30 m tall in Oceania. The species staple crop for food security the tropics. Tree loss from tropical windstorms, together with transition toward high-density planting has driven an interest dwarf phenotype species. Information on dwarfing rootstocks breadfruit currently limited. aim this study was to assess performance growth lakoocha lakoocha) as rootstocks. We compared trees those self-graft and non-graft within 21 months after grafting. These led discovery rootstock-induced trait scions displayed reduction height, stem thickness, internode length, fewer branches leaves, resulting about 32% standard height at end suggest have potential control vigor. Non-structural carbohydrate analysis showed composite exhibited lower hexose concentration both scion stems roots, but higher sucrose level stems, starch roots. significance these parameters rootstock discussed.
