| Abstract | ||||
| This research was carried out during 2009 and 2010 growing seasons on Om-El fahm almond transplants at the South of Tahrir Research station Aly; Mubarak farm, to study the effect of grafting dates (Mid- July, Mid- August and Mid- September) and on different rootstocks (Bitter almond, Okinawa peach and Nemagaurd peach ) on the growth aspects; scion survival percentage (final take) scion length ,scion girth, root length, No. of main roots/ plant, top dry weight, root dry weight and budding dry weight and leaf mineral nutrient concentrations . The obtained results clarified that grafting survival percentages, scion lengths, stem girth (10 cm above union zone), top dry weight and buded dry weight significantly increased when it grafted on July followed by August and then September through the two growing seasons. On contrast stem girth (10cm below union zone), total root length, No-of main roots/ plant and root dry weight significantly increased when it grafted on September followed by August and then July during two growing seasons. Using of bitter almond as a rootstock for Om-El fahm cultivar almond significantly increased grafting survival percentages compared with the other two studied rootstocks through the study.. On the other hand, using Nemagaurd peach rootstock recorded significantly the highest values of the other growth parameters followed by Okinawa peach and finely Bitter almond through both growing seasons. Data also showed that grafting of Om-El fahm almond generally had the highest significant value of mineral leaf nutrient elements when it grafted in July during the two growing seasons. Using Nemagaurd peach as a rootstock for Om-El fahm almond significantly increased leaf nitrogen content compared with the other two studied rootstocks throughout the two growing seasons. On the other hand, grafting of Om-El fahm almond on bitter almond rootstock generally had a high significant values of leaf P, K, Ca and Mg mineral concentration nutrient elements compared to the other studied rootstocks during the two growing seasons. As a conclusion; from the data conclude that the best time for grafting of Om-Elfahm almond cultivar were mid-July. The best rootstocks for Om-El fahm almond cultivar were Nemaguard peach to obtain vigours vegetative growth and bitter almond for heightest survival percentage. | ||||
