This investigation was conducted on fruitful trees of sweet orange ″Citrus sinensis L.″ belonging to Hamlin cultivar budded on three citrus rootstocks sour orange, rough lemon and Balady lime to investigate the citrus rootstocks combined with geographical direction (north and south) on: a) fruit quality; b) creasing incidence and c) nutritional status (leaf and fruit rind mineral composition). Obtained results revealed that highest creasing % of Hamlin fruits was associated with the Balady lime rootstock, while the reverse was detected with rough lemon. On the other hand, the northern side of tree periphery gave the highest creasing% compared with south side. As for the effect of fruit status from which fruit peel and adjacent leaves, results revealed that peel of the normal fruits and leaves nearer to them characterized by their significant higher Ca, Mn and Zn contents over the creased fruits. The reverse was true with N, P, K and Mg, whereas rind of creased fruits and adjacent leaves exceeded statistically the analogous ones of normal fruits. Moreover, Fe and Cu had no firm trend in this respect. |
