Abstract

The rooting response of Theobroma cacao L. stem cuttings to auxin treatments of 0, 25, 100 and 1,000 ppm concentrations of napthalene acetic acid (NAA) and indolebutyric acid (IBA) were determined.

Cuttings were obtained from mature orthotropic branches of 'Trinitario' cacao. The cuttings were soaked in solution form of the growth regulators with various concentrations for 30 minutes, prior to planting in sand rooting medium under continuous mist during daytime.

Rooting response of cacao stem cuttings was most favorable when treated with 100 ppm concentration of NAA and IBA Eight weeks after treatment, the number of cuttings that rooted was higher, the count of roots per cutting was higher, roots were longer, the percentage rooting was higher, and the percentage deterioration was lowest
