Abstract:

The floral bud differentiation processes on apical meristem of flue-cured tobacco induced with low temperature were observed by stereomicroscope. The results showed that this method was simpler and faster than that of scanning electron microscope and paraffin section. It revealed that the stereomicroscope is more superior in showing the spatial characteristics of meristem than that of the scanning electronic microscope method, and the image is more complete. It also validated the uniqueness of the inflorescence initiation of flue-cured tobacco lateral shoot which was observed by scanning electron microscope, and this uniqueness could not be captured or found by paraffin section.
