| Abstract | ||||
| Four experiments were carried out during 2000/2001 and 2001/2002 seasons 10 study the suitable horticultural procedures for three local polyembryony mango cultivars (Hindy Sinnara, While Sukkary and Zebda) were tested for compatible grafts with scions of Fagri Kalan,Ewais and Alphonso mango cultivars. The results revealed that earlier elimination of sex embryos just after germination enhanced production of nucellar seedlings. Husked seeds gave the highest number of germinated embryos per seed and fast germination followed by cracked seed coal treatment Also,Zebda seeds had the highest number of vegetative embryos and more vigorous seedlings followed by White Sukkary then Hindy Sinnara. White Sukkary and Zebda seedlings were more tolerant to frequency of irrigation intervals than Hindy Sinnara seedlings. With regard to the percentage of graft success and scion growth criteria,it is beUer to graft Ewais and Fagri Kalan on Zebda seedlinqs.whtle Alphonso scion on White Sukkary is recommended. Histological study at the graft union zone of incompatible grafts(Ewais on Hindy Sinnara and Alphonso on Zebda) revealed presence of necrotic layer on both sides of union zone.scattered callus and numerous free of callus positions that lead to weak or fail connection between two graft parteners. Meanwhile,lighl microscopic examination at the grafting zone of analogous compatible grafts Ewais and Alphonso on White Sukkary revealed a condensed and uniformly callus tissue,smallest necrotic spots and initiation of new vascular elements, hence scion continued survival and had good growth. | ||||
