Plant Physiology textbooks and water relations books, like those by Paul
Kramer, are good sources of information on cavitation and drought. Are you
interested just in drought resistance, or also in mechanisms of drought
avoidance?  Increasing CO2 would probably act more to help plants avoid
drought by reducing the size of stomatal openings and thereby reducing
transpiration.
