ABSTRACT: To achieve high crop yieldin agriculture,
the production of plantlets of superior quality is one of thebasic
prerequisites. For conilon coffee, the current recommendation in theproduction
of clonal plantlets through vegetative propagation is to usediagonal cuttings,
in bevel form. However, there are indications that othertypes of cutting have
been successfully used to produce plantlets. In thiscontext, this experiment
was conducted with the objective of studying thedevelopment of plantlets of
conilon coffee obtained by different types ofcuttings. The experiment was
conducted in a greenhouse. The cuttings wereobtained from the middle portion of
orthotropic stems of standardized plants.The experiment followed a split plot
in time design, with three types ofcuttings (bevel, sharp bevel and straight)
and two times of evaluation, withfour repetitions. At 30 and 120 days after
planting, plantlets were collectedand evaluated. The results show the increase
occurred in the variables due tothe straight cut when compared to the others,
except for stem diameter.Emphasizing in this context, the straight cut promoted
an increase in seedlingheight, production of biomass and in the Dickson’s
quality index when comparedto cuttings in bevel and sharp bevel.
