Abstract: The potted Bougainvillea glabra ‘Sanderiana’ was used as the test variety. Under natural growth conditions, the orthogonal experiment design was used to analyze the influence of different concentrations of paclobutrazol, COMP, and A-MICSUR amalgam on the regulation of the florescence of B. glabra ‘Sanderiana’. The results showed that paclobutrazol had the greatest effect on growth of Bougainvillea branches, which manifest in inhibiting the elongation of branches internodes and promoting the increase in the number of blossom buds; A-MICSUR had the greatest effect on the regulation and control of Bougainvillea florescence, which manifest in promoting blossom and improving quality; The 3 medicaments had different effects on the enzyme activity of Bougainvillea. The regulation of the florescence of B. glabra ‘Sanderiana’ was mainly based on effect of the timing florescence. The optimal combination of medicaments was paclobutrazol 1.2 g·L-1 + COMPO 1.5 g·L-1 + A-MICSUR 0.5 mL·L-1, and combined with appropriate plant water management.
