摘　　要：探讨了阴性植物和阳性植物对环境的适应机制。光的吸收能力和对活性氧的清除能力两者共同决定了活性氧的积累程度,从而决定了植物对环境的适应能力。阴性植物不耐强光是由光强和温度两个生态因子共同作用的结果,单一因素通常不会导致活性氧的过度积累而对植物造成伤害。阳性植物不仅对光的需求量较高,而且具有较高的抗氧化能力。光照强度对药材质量和产量有密切关系,在生产中确定适宜的光照是优质高产的关键。This article discussed adaptation mechanism of shade plants and sun plants to the environment. The absorptive capacity of the light and the scavenging capacity of reactive oxygen species （ROS） determine the accumulation of ROS, and further determine adaptability of plants to environment. The shade plants are intolerant to hard light due to the combination of light-intensity and temperature of two ecological factors. Usually, neither of two factors lead to excessive accumulation of ROS, and do damage to plants. Sun plants have a higher demand for light and antioxidant capacity. Light-intensity has a close relationship to the quality and yield of Chinese medicinal materials. The suitable light-intensity is the key to improve quality and output in production.
