ABSTRACT: the rooting potential was determined from the propagation by cuttings of an old specimen, preserved in a Galician garden (Spain), and three commercial Camellia japonica cultivars, with the aim to use this cloning technique to propagate this old cultivar and the commercial cultivars in Galician nurseries. Treatments used were liquid or talc formulations, with different concentrations of indol butyric acid, and its potassium salt (AIBK), or combinations of indol butyric acid and naphtalenacetic acid. Half of the rooted cuttings were injured in the base. Only the cultivar 'Patricia Ann' showed a good rooting potential, since 75% of the controls rooted, whereas the other three cultivars showed very low rooting rates (0-15 %). Best rooting rates and visual rooting index were obtained with combinations of indol butyric acid and naphtalenacetic acid in talc, both in injured and non injured plants. Key words: macropropagation, rooting auxins, injury, solvent, hormone concentration. |
