| 摘 要： | 以朱顶红的3个品种为研究对象，研究了不同遮光处理（全光，遮阴度为30%、60%、90%）对其生长量及净光合速率日变化、净蒸腾速率日变化的影响。结果表明：3个朱顶红品种的叶长、叶宽、叶面积、花葶高度均随着遮阴处理程度的加大而显著增加，而花冠大小及花色无明显差别；3个朱顶红品种在30%的遮光下全天的日平均净光合速率最高，全光下日平均净蒸腾速率最高。结论：3个朱顶红品种更适宜在30%的遮光环境下栽植。

| Abstract: | 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. |
