The plants cultivated in flowerpots or in breeding grounds or conservatories, are in artificial conditions and little comparable with respect to a condition of field. Dimensions of the flowerpot must be based on the space requirements, considering the architecture and the speed of grout of the roots, as well as its phonological development. The traditional flowerpots do not allow physiological evaluations by the root in situ, an alternative is the use of rhizotron, which, by a side allows to evaluate dynamics and radical grout in situ and by another one diminishes the flowerpot effect. In the present work a model of rhizotron with dimensions sets out 42 X 30 X 10,5 cm with curve-slide sidewalls which allow to place it in three different positions with a depth corresponding to each one from the indicated dimensions. The design allows simultaneously to open to the face corresponding to the superior part or point where the plants plows placed and to lateral one through which the taking of ground samples or root or the registry of variable like pH or soil humidity among others. We propose this device for their use in investigation and teaching.Keyworks: grout root, root circling, shoot/root rate, root system configuration, pot dimension.
