Effects of water stress on physiological characteristics of different Illicium lanceolatum ecotypes under low light intensity

Low availability of soil moisture is considered a major limiting factor for plant growth and crop yield worldwide, and it turns to be a more serious problem under the context of global change. A weak light stress, resulting from significantly lower light intensity than light saturation point of plant in long time, will affect the morphogenesis and physiological and biochemical processes of plant. The Chinese anise (Illicium lanceolatum), a traditional medicinal plant in China, has high content of shikimic acids which have effects of antiphlogosis and analgesis, and can reduce platelet aggregation and suppress vascular and cerebral thrombosis.
