| Abstract | ||
| This study was carried out in the experimental orchard of Horticultural Research Institute, Agriculture Research Center, Giza Governorate, Egypt through 2017 and 2018 seasons. The main aim was to find out the most reliable carob (Ceratonia siliqua L.) grafting technique (cleft with apical and axillary buds, saddle with apical and axillary buds, cleft with axillary buds and saddle with axillary buds) and the suitable grafting date (15th February, 15th March or 15th April). Results showed that cleft with axillary buds grafting proved to be the best technique regarding modified success percentage, leaves number, scion and rootstock diameters. Cleft with apical and axillary buds grafting technique recorded the highest modified survival percentage and vegetative growth length values. February was the best grafting date concerning vegetative growth length, leaves and sprouted shoots numbers. Modified survival percentage and grafting union diameter were improved in March. Using saddle with axillary buds grafting in February and March produced the maximum sprouted shoots number, whereas using it in March recorded higher grafting union diameter value. Vegetative growth length and modified survival percentage were improved using cleft with apical and axillary buds grafting technique in February and March, respectively. Both cleft with axillary buds and with apical and axillary buds grafting techniques were the best regarding grafting union examination. It can be recommended that, carob can be vegetatively propagated by using either cleft with axillary buds or with apical and axillary buds grafting techniques. Also, grafting carob can be done in February or March. | ||
