In citrus growing, rootstocks that regulate scion growth have important roles. But it is not clear how the rootstocks regulate scion vigor. In this study, we selected three citrus rootstock cultivars, flying dragon (Poncirus trifoliata var. monstrosa) as a dwarfing rootstocks and swingle citrumelo (P.trifoliata X Citrus paradisi) as a vigorous with trfoliate orang (P.trifoliata) as a control. Tender buds from new shoot of Lemon 'Eureka' were cleft grafted on etiolated rootstocd seedlings. Eighteen months after grfting, dry matter of each part of young trees was measured. The order of top weight was the best on swingle citrumelo and worst on flying dragon. But the difference among rootstocks was not detected in the underground part. Endogenous indole acetic acid (IAA) and abscisic acid (ABA) in the new shoot was measured. IAA levels on swingle citrumelo was the highest and lowest on flying dragon. There were no distinct differences in ABA levels.
