In situ Phenotyping of Grapevine Root System Architecture by 2D or 3D Imaging: Advantages and Limits of Three Cultivation Methods
2021
International audience; The root system plays an essential role in the development and physiology of the plant, as well as in its response to various stresses. However, it is often insufficiently studied, mainly because it is difficult to visualize. For grapevine, a plant of major economic interest, there is a growing need to study the root system, in particular to assess its resistance to biotic and abiotic stresses, understand the decline that may affect it, and identify new ecofriendly production systems. In this context, we have evaluated and compared three distinct growing methods (hydroponics, plane, and cylindric rhizotrons) in order to describe relevant architectural root traits of …

Pea (Pisum sativum L.) is the most cultivated seed legume in the world after common bean. But it issubject to a disease against which there is no effective treatment, root rot caused by Aphanomyceseuteiches. The only sustainable solution to control A. euteiches is genetic control. Previous studies haveidentified a positive correlation between the root area or biomass of lines and their level of resistance toroot rot caused by A. euteiches. The aim of the internship, which was part of the research project"Diversification and Combination of Aphanomyces Resistance QTLs in Protein Pea (DORA)", was toidentify whether changes in the components of the root system architecture of pea are induced by…
