It was learned on April 20 that " an efficient and high-definition fluorescence microscopy method for observing the growth of plant pollen tubes in pistils " completed by researchers such as Xu Yuanqing and Luo Zhonglai of the South China Botanical Garden of the Chinese Academy of Sciences was authorized by the national invention patent
The fluorescence microscopy method of the invention greatly weakens the phenomenon of the luminescence of the pistil itself, and reduces the interference to the observation of pollen tubes when the magnification is large, so that it is easy to obtain a high-definition image of the growth of the pollen tube under high magnification.
