Propagation of Mango by cleft-grafting
Barakat M. Yousif , Osman M. Elaminand , Mohamed E. Elkashif
Abstract:
Experiments were conducted at the Faculty of Agricultural Sciences,
University of Gezira, Wad Medani, Sudan during the period December
2001-December 2002, to investigate the use of cleft grafting technique
for mango propagation, where the scion is detached from the parent tree.
The treatments were rootstock diameters of 1.5, 1.5 to 0.5 and 0.5 cm;
scion hardening methods in which the leaves were either removed or
trimmed to half leaves; scion lengths of 8-9 or 15-16 cm; glasshouse and
nursery shed conditions and two cultivars, namely Galbeltor and
Abusamaka. The most viable scions with the highest number of successful
grafts were obtained when scions in which all the leaves were removed
were grafted on rootstocks of 0.5 cm in diameter. There were no
significant differences between the two mango cultivars, but Galbeltor
tended to have higher values. Longer scions resulted in significantly
higher percentage of successful grafts than shorter ones. Grafted
seedlings kept under glasshouse conditions resulted in 100% successful
grafts as compared to those kept in the nursery shed due to the high
relative humidity levels maintained in the glasshouse.
