Abstract
The experiment was conducted
at the nursery of Hill Agricultural Research Station, Khagrachari from August
2009 to February 2010 to find out the effect
of rootstock and grafting method on the success and growth of sweet orange
(Malta). The experiment
consisted of two factors with four
rootstocks (Rangpur lime, Rough lemon,
Kalamanchi and Pummelo) and three
grafting method (Cleft,
Veneer and Splice grafting). The highest
percentage of graft success (86.3%) was found in Rangpur lime (R1),
while the lowest (81.9%) in Kalamanchi (R3). The highest
percentage of graft survivability (77.3%) was recorded in Rough lemon (R2)
and Pummelo (R4) while the lowest (75.1%) in Kalamannchi (R3).
The highest percentage of graft success (91.1%) was found in Cleft grafting (G1)
and the lowest (76.7%) in Splice grafting (G3). The highest
percentage of graft survivability (83.0%) was found in Cleft grafting (G1)
and the lowest (68.8%) in Splice grafting (G3). The highest
percentage of graft success (94.2%) was observed in Rough lemon in Cleft
grafting (R2G1), whereas
the lowest (74.2%) was recorded in Rough lemon in Splice grafting (R2G3). The highest percentage of graft survivability (87%)
was observed in Pummelo in Cleft grafting (R4G1), whereas the lowest (66.0%) was recorded in Rough
lemon in Splice grafting (R2G3).
