Drought tolerance processes in soybeans
- 1 Institut National de la Recherche Agronomique, Station d'Amélioration des Plantes de Montpellier, Montpellier Cedex, France
Fifteen soybean cultivars were evaluated in two water supply conditions, inducing or not a drought stress. Main canopy traits were measured several times during the reproductive period and, at maturity date, the yield components were estimated. Using principal components analysis, the main physiological functions involved in soybean drought tolerance are described: leaf cells enlargement and assimilates transport. These processes could be a good basis on which to define new selection criteria for soybean drought tolerance.
