Types of conduction of yellow passion fruit and its influences on productive characteristics

Abstract

Passion fruit has continuous and indeterminate growth, requiring conduction for better distribution
of branches in the support structures. The objective of this work was to evaluate to biometry and productivity of yellow passion fruit (Passiflora edulis Sims) grafted with different types of conduction of the secondary branches. The experiment was installed and conducted in Pracinha, SP, Brazil, from May 2016 to April 2017, adopting the experimental design in randomized blocks with four reatments and six replicates. The treatments consisted of the
following types of secondary branch conduction: T1 – main branch pruning leading a side secondary branch; T2
– main branch pruning leading two side secondary branches; T3 – fold the main branch leading a side secondary
branch; T4 – fold the main branch leading two side branches. The length of secondary branches, number of tertiary branches, length, diameter and mass of fruits, number of fruits per plant and yield (kg.ha-1) were evaluated. There were no significant differences for number of tertiary branches, length, diameter and mass of fruits. It was observed that the number of fruits per plant and the yellow passion fruit productivity are influenced by the type of conduction
of the secondary branches that does not alter the physical characteristics of the fruits. Fold the main branch leading two side branches favor the development and production of the yellow passion fruit.
