Résumé
The drivers underlying the development of deep root systems, whether genetic or environmental, are poorly understood but evidence has accumulated that deep rooting could be a more widespread and important trait among plants than commonly anticipated from their share of root biomass. Study data on the drought resistance of Teak in northern Laos over a 2-year period. Measurement of effects on above-ground parts and specific study of changes in deep rooting (12M) in response to the effect of rain exclusion. Monitoring of climate data Monitoring aboveground growth and functional traits Assessment of carbon stocks in coarse and fine roots Monitoring of root demography
