Abstract:
This work is a bibliographic presentation of an important and fundamental device for research
on the plants roots field, which is a Rhizotron. We present all the types of rhizotrons used in the study
of the growth and roots development of by addressing the structure and uses, and potential
applications.
We found several types of rhizotrons proposed by several researchers, where the type vary
according to uses. Some of them are used for pedagogic purposes, others are for purely research
purposes. The development of digital devices played a major role in this field by providing highresolution
images that can be used in image-processing programs. This software are constantly
evolving to show more data about roots.
Finally, we discussed the methods which are used in root measurements, which give an idea of
the ways and methods of growth and development of roots .
