Under drought stress, mycorrhizal O. europaea seedlings showed significantly higher photosynthetic and transpiration rates, stomatal conductance and foliar P concentration than its similarly-sized non-mycorrhizal counterpart. The intrinsic water use efficiency (photosynthetic rate to stomatal conductance ratio) was not change in O. europaea and decreased in R. lycioides seedlings due to mycorrhizal colonization under both well-watered and drought-stress conditions.
