Abstract: Using plant growth regulator triacontanol (TA) as raw material, five experimental groups were built for the control study of the effects on the growth of kelp seedlings’ algae soaked in different concentrations of TA. The study showed that kelp seedlings soaked in TA with the concentration of 0.8 ppm yielded the best result, the production was increased by 20.5%, followed by kelp seedlings soaked in TA with the concentration of 1.0 ppm and 1.5ppm, with the production being increased by 16.3% and 13.1% respectively. It also showed significant effect of TA on the kelp seedlings’ growth rate, algae color, width and disease resistance.
