研究发现施氮后不同基因型油菜叶片LMA变化主要由栅栏组织厚度和叶肉细胞密度主导，栅栏组织厚度增加同步促进CO2叶肉导度和LMA，协同光合速率和LMA变化；细胞密度增加了细胞壁与Rubisco对氮的竞争，降低光合速率、促进LMA。氮肥施用缓解了细胞壁与 ...

This film explores the complexity of vocal cord vibrations, which occur too rapidly for the naked eye or standard cameras to perceive. By using ultra-high-speed photography at approximately 5,000 ...
