Experiments were designed to assess the capacity of an in vitro cultured CAM plant to control water loss and to examine the response of their stomata to various factors. Detached leaves of micropropagated Agave tequilana plants lost water at similar rates as did field-grown plantlets when dehydrated in air. This was consistent with the fact that stomata from micropropagated plants show similar morphology than field-grown plantlets. In addition, stomata from micropropagated plants responded to various factors in a manner similar to those from field-grown plantlets. It appears that in vitro culture does not affect the capacity of leaves to control water loss nor does it alters the nocturnal stomatal opening of this CAM plant.
