Abstract: An investigation was conducted to study the effect of growth regulators and environment on biochemical changes and rooting of cutting of cuttings in cocoa. In this present investigation also C:N ratio was higher in long cuttings in both plagiotropic shoots (10.15) and orthotropic shoots (9.73) which have proven to record high percentage of sprouting and rooting than two node cuttings. Cuttings treated with IBA 10000 ppm registered high phenol content in plagiotropic (1.93 mg/g) as well as orthotropic shoots (1.76 mg/g) than other treatment. The peroxidase content was slightly higher in IBA 7500 ppm treated cuttings in both plagiotropic (1.15 change in the OD 430 nm / min / g) and orthotropic shoots (0.58 change in the OD 430 nm / min / g). Thus, the best treatment combination was found to be that of plagiotropic long cuttings treated with IBA 7500 ppm. But some more limiting factors need to be assessed for getting higher success percentage and make this a method for mass multiplication of cocoa through cuttings as a feasible venture.
