| 摘 要： | 光合作用是植物进行空气营养的一种方式，是绿色植物组织的基本功能，但是环境中的各种因素都会影响该过程。通过荧光光谱测定燕麦（Avenna sativa L，cv Prevision）植株的离体完整叶片的吸收光谱和作用光谱来探究影响光合作用的各种物理和化学因素，如高光强、高温、除草剂3，4-二氯苯-1，1-二甲基脲（DCMU）等。该实验方法适合植物生理学或生化专业的学生进行课外拓展研究。

| Abstract: | Photosynthesis,which is the basic function of green plants,is a way for plants to obtain nutrition from the air.However,it can be affected by kinds of environmental factors,such as high temperature,high light intensity and the herbicide 3-(3,4-dichlorophenyl)-1,1-dimethylurea(DCMU).A method to inquire the stress infections of the factors above was provided by testing the absorption and action spectrum of intact oat leaves during the process of photosynthesis.This method can be applied to the college student... |
