Abstract:
The flower bud morpho-differentiation under shade of Euphorbia pulcherrima was studied with the cultivars of ‘Gold medal’.The results showed that flower bud differentiation began at 24 days after shading，the process of flower bud differentiation lasted for about 38 days，it could be divided into four stages，i.e.Undifferentiation phase，apical elongation phase，inflorescence and small floral primordium differentiation phase，flower organ differentiation phase，bract number of the plant and flower bud differentiation process was significantly related.
