ABSTRACT: The influence
of two grafting techniques on the success of stenting (simultaneous cutting and
grafting) and some ensuing growth parameters of stentlings were studied
under glasshouse conditions. The Avalanch and Peach Avalanch glasshouse rose
varieties were utilized as scion and grafted on R. manetti as
rootstock. Two grafting techniques namely, splice and omega grafting
methods were practiced and graft combinations were inserted in cocopeat-perlit (1:2)
medium under mist system. The number of roots, longest root size, shoots and leaf
numbers and successful grafting percentage were evaluated after grafting. In Avalanch/R. manetti and Peach Avalanch/R. manetti combinations, higher percentage
of successful grafting was observed in the stentlings propagated via
omega grafting technique. Furthermore Avalanch/R. manetti stentlings
prepared by omega grafting were found to produce more number of
roots, shoots and leaves and longest root size as compared to those propagated
through splice grafting method. In case of Peach Avalanch/R. manetti combinations
propagated via omega grafting more number of shoots was observed as compared
to those propagated by splice method. However, these were not significantly
different with respect to their leaf numbers. The results showed the
superiority of omega grafting procedure.
