Rooting and growth of cacao tree cuttings (clones Cepec 42, tsh 516 and tsh 1188) treated with indolbutyric acid (iba)

Herbaceous cuttings of plagiotropic branches of cacao tree (clones CEPEC 42, TSH 516 and TSH 1188) were treated with 0 or 6,000mg.kg-1 of indolbutyric acid (IBA) and placed in small pots of 288cm³ containing a mixture of Plantmax® + triturated coconut fiber (1:1), enriched with Osmocote® (19-06-20) and PG mix® (14-16-18). The pots were kept in a chamber equipped with an intermittent misting system. The evaluation was carried out 78 days after striking, and it was verified an increasing of 87% of the cutting rooted for all clones tested, regardless of the IBA treatment. The IBA treatment increased the survival and rooting indices of all clones, as well as the numbers of roots (clones TSH 516 and TSH 1188), root dry weight (clones CEPEC 42 and TSH 516) and shoot dry weight (clones TSH 516 and TSH 1188).
