| 摘 要： | 从遮荫对草本植物的生长环境、生理生化特性、形态解剖结构、营养分配及产量影响方面进行了综述.遮荫可明显改变草本植物的生长环境,进而对其生理生化特性及产量产生较大的影响.草本植物为适应荫蔽的环境,导致在光合作用单位、电子传递、光合色素含量、内源激素及酶活性、植株形态解剖结构、营养物质的吸收及分配等方面产生变化,以保证在遮荫下仍能充分利用光能,维持生长所需的能量平衡,进行正常的生命活动.

| Abstract: | This paper summarized shading effects on growth environment,physiological and biochemical characteristics,morphological and anatomical structure,nutrient allocation and yield of herbage plants.Shading could change plant growth surroundings and remarkably affected physiological and biochemical characteristics and yield.As a result of adapting shaded environment,large variations took place in photosynthetic unit size,electron transmission,pigment content,endogenous hormones and enzyme activities,morphological and anatomical structure,nutrient absorption and distribution to ensure fully utilizing light energy at shading conditions,and to maintain its energy equilibrium and normal life activities. |
