Nurlaeni Y, Surya MI. 2015. Response of Camelia japonica shoot cuttings on organic Plant Growth Regulator. Pros Sem Nas Masy Biodiv Indon 1: 1211-1215. Camelia japonica L. is a herbaceous plant which has the potential as ornamental and medicinal plants. Application of plant growth regulators (PGR) is an effort to increase the quality of seedling through vegetative propagation. However, a good quality of organic PGR relatively has not been developed yet. This study aimed to examine the provision of organic plant growth regulator on the growth of Camelia japonica shoot cuttings. The experiment was arranged in a completely randomized design with 5 replications. The factors were various concentration of organic PGR such as 0%, 5%, 25%, 50%, 100%. Rootone-F with a dose 2 g/mL was used for comparison. The observed growth parameters were the percentage of live cuttings, root number, root length, stem diameter, callus diameter, number of flowers, wet weight of plant and dry weight of plant. The results showed that there is no significant difference between organic and synthetic PGR. The difference is only visible on plant fresh weight parameters, with the highest value in the treatment of 25% organic PGR. It indicates that the organic PGR has the same ability with synthetic PGR to stimulate the growth of Camelia japonica shoot cuttings.
