  abstract = {{U}nderstanding better the interactions between root systems in associated crops is significant for basic knowledge in plant science and to help designing cropping systems. {C}urrent research on inter-specific root interactions concentrates on static descriptions of the horizontal extension of root systems or on the dynamics of provoked root encounters. {T}his study considers detailed observations of the dynamics of inter-specific root interactions, in the vertical plane, at both the whole root system and the individual root levels. {C}orn and young rubber trees were grown in association in artificial conditions that excluded the possibility of competition for resources, using rhizoboxes, i.e. thin containers with a transparent wall. {T}he paper presents novel approaches, such as the study of root system growth trajectories, to document root system development in terms of overall growth rate, colonization of soil space and individual root growth patterns. {I}t was found that (i) corn roots developed towards rubber roots until a contact was established, (ii) rubber roots expanded faster and more vertically in association with corn, (iii) the expansion rates of both root systems varied concomitantly and (iv) inter-specific root encounters resulted in reduced elongation rates in both species. {I}mplications of these results for corn/rubber inter-cropping are discussed. {T}his work advocates in favour of a better understanding of under-ground facilitative effects between species. {I}f understood enough to be manipulated, such knowledge might become a powerful tool for the design of more sustainable and efficient cropping systems.},
