Abstract:: Using Euphorbia pulcherrima Willd ‘Gold Medal’ as the material，the effects of PP₃₃₃ and shading on the growth and flowering of Euphorbia pulcherrima Willd were studied.The results showed that compared with water treatment，foliar spraying PP₃₃₃ had obvious influence on the plant height，canopysize，the branches and the leaves of Euphorbia pulcherrima Willd，plant height and internode were more shorter，leaves color were more deeper，the ornamental vaule were better too.The most suitable concentration of PP₃₃₃ ranged from 15 to 30 mg/L.Flower coloring and flowering phase were two months earlier under shading treatmax than natural illumination.
