Abstract

  This investigation was conducted in 2019. The present study was carried out in a field at the citrus experimental station in Ciano, the General Corps of Scientific Agricultural Researches. The fruit maturity development of orange trees (Washington Navel 141) budded on seven citrus rootstocks (Sour orange, Citrumelo 4475, Citrumelo 1452, Troyer Citrange, Carrizo Citrange, Macrophylla, and Cleopatra Mandarin) and farmed in 1989 have been studied. The results showed a significant increase in fruit fresh weight in trees grafted on Citrumelo 1452 by (107.93%) compared to the increase in fruit fresh weight in trees grafted on Sour orange by (58.65%). Fruit peel thickness significantly increased by (6.68%) in trees grafted on Troyer Citrange compared to those grafted on Sour orange, Citrumelo 4475, and Macrophylla whose fruit peel thickness decreased by (22.65, 13.55 and 11.46%, respectively). The largest significant increase in total soluble solids (%) was in trees grafted on Macrophylla by (57.29%), while total acids (%) significantly decreased by (74.25%) in trees grafted on Cleopatra Mandarin.

Keywords: Navel, Maturity, Fruit, Cleopatra, Citrumelo.
