COMPATIBILITY OF GRAFTING IN THREE CLONES OF GUANABANA (Annona muricata L.)

Abstract

Objective: The goal for this research was to select and evaluate the grafting compatibility of three guanabana clonesb(Annona muricata L.).
Desing/methodology/approximation: Scions with an average of 10 vegetative buds, 15 cm of length and 0.5 cm of diameter were grafted, by the method of cleft graft in rootstocks of 9 months of age with a height between 30 cm and 50 cm and a diameter between 0.4 cm and 0.5 cm. A completely randomized design was used, with three treatments (Clone 8, Clone 9 and Clone 10), with four repetitions and eight experimental units per repetition making a total of thirtytwo plants per treatment.
Results: At 27 days after grafting, Clone 10 (T1) and Clone 8 (T2) showed a 96.8% against 90.6% Clone 9 (T3), although there were no significant statistical differences among the three grafted clones.
Study limitations/implications: The results indicating that the genetic factor (clone) does not affect the grafting of this species and that from an anatomical point of view, that there is vegetative compatibility and cellular recognition of the vascular tissues between the rootstock and scion, with the grafting method used in this work.
Conclusions: This defines, that there was not an effect of the inert clone on the successful grafting (95% average) using the cleft graft method.
