In conclusion, this study has shown a clear distinction between the respective anisohydric and isohydric drought responses of C.
Based on these preliminary results, common ash and silver poplar would be classified as isohydric species; as "drought avoiders of the saving type", whereas common beech and Downey oak as anisohydric species; as "drought avoiders of the spending type" [7].
Isohydric plants have a high degree of stomatal control enabling them to maintain high leaf water potentials during the day for extended periods of drought, thus preventing cavitation.
--Cooling of the system and isohydric crystallization of LiCl[O.sub.4]*3[H.sub.2]0 are performed in the crystallizer.
These findings could be related to the fact that maize is an isohydric species that tends to maintain a quite constant day-time leaf water status by varying stomatal conductance (Tardieu, 1996).
Such behavior in response to early stages of soil water depletion has been described as isohydric, a behavior shared by cowpea [Vigna unguiculata (L.) Walp], maize (Zea mays L.), and several other crop plants (Tardieu and Simonneau, 1998).
