The effects of different shading treatments (full light, shading treatments degree of 30%, 60%, and 90%) on the growth, net photosynthetic rate, and net transpiration rate of three Hippeastrumcultivars were studied. The results showed that the leaf length, leaf width, leaf area and scape height of the three Hippeastrum cultivars were increased obviously, as the deep of shade treatment. But there was no significant difference in the size and color of the corolla. The three Hippeastrumm cultivars had the highest average daily net photosynthetic rate under 30% shading, and the net transpiration rate were biggest in full light. Conclusion: The three Hippeastrum cultivars were suitable for planting under the 30% shading.
